Alkali-activated mortars and concretes have been gaining increased attention due to their potential for providing a more sustainable alternative to traditional ordinary Portland cement mixtures. In addition, the inclusion of high volumes of recycled materials in these traditional mortars and concretes has been shown to be particularly challenging. The compositions of the mixtures present in this paper were designed to make use of a hybrid alkali-activation model, as they were mostly composed of class F fly ash and calcium-rich precursors, namely, ordinary Portland cement and calcium hydroxide. Moreover, the viability of the addition of fine milled glass wastes and fine limestone powder, as a source of soluble silicates and as a filler, respectively, was also investigated. The optimization criterium for the design of fly ash-based alkali-activated mortar compositions was the maximization of both the compressive strength and environmental performance of the mortars. With this objective, two stages of optimization were conceived: one in which the inclusion of secondary precursors in ambient-cured mortar samples was implemented and, simultaneously, in which the compositions were tested for the determination of short-term compressive strength and another phase containing a deeper study on the effects of the addition of glass wastes on the compressive strength of mortar samples cured for 24 h at 80 °C and tested up to 28 days of curing. Furthermore, in both stages, the effects (on the compressive strength) of the inclusion of construction and demolition recycled aggregates were also investigated. The results show that a heat-cured fly ash-based mortar containing a 1% glass powder content (in relation to the binder weight) and a 10% replacement of natural aggregate for CDRA may display as much as a 28-day compressive strength of 31.4 MPa., This research was funded by FCT-Fundacao para a Ciencia e Tecnologia, grant number SFRH/BD/111813/2015.

A healthy built environment is an issue of crucial importance, especially in the context of the dramatic Covid-19 outbreak. Also, according to The Serum Institute, the world largest vaccine manufacturer, there will not be enough doses to inoculate the entire world until 2024. That fact is independent discovery of the alarming consequences of the post-Covid syndrome (“long Covid”). As it is briefly discussed in this chapter, the necessary interactions between the many researchers of the different areas of the world whose work has connections to the built environment-namely, civil engineers, architects, microbiologists, and epidemiologists-are rare, thus hampering the efforts needed to tackle the pandemics. The objective of this multiauthored text to is provide the necessary background to learn about virus, bacteria, and fungi in the built environment and methods to eradicate or reduce their numbers., (undefined)

In recent years, people have started cutting down on plastic consumption, as they have realized the effects plastic can have on the environment and our oceans. For example, in a recent report, published in SCIENCE magazine, researchers claim that by 2050, we will have produced more than 26 billion tons of plastic waste and that almost half of that will be dumped in landfills and the environment. A high-level scientific review that appeared in Plastic Oceans also states that eight million tons of plastic is dumped in our oceans every year. Ben Webster, the Oceans Correspondent for The Times also alleges in a recent published article that the frozen Arctic Ocean contains up to 12,000 tiny pieces of plastic per liter of sea ice, showing that even the most remote parts of the planet are highly polluted with plastic waste and in a recent study published in the Guardian, a team of Australian scientists insist that up to 90% of seabirds have plastic waste particles in their guts, which they have mistakenly mistook for fish eggs. Given the Plastic Pollution Crisis and its environmental impact, plastic is finally receiving the attention it deserves with much greater emphasis on recycling, reuse, and reduction. In recent years researchers working in the field of civil engineering have been engaged in investigations about the reuse of waste plastic in construction materials. For the first time, in one comprehensive volume, Use of Recycled Plastics in Eco-Efficient Concrete presents a state-of-the art review on the application and use of recycled plastics in concrete construction. Divided over three parts, Part 1 begins by looking at the processing of plastic waste, including different separation techniques. Part 2 focuses on the production and performance of concrete with different types of recycled plastic as an aggregate or binder replacement. Part 3 looks at the manufacturing, properties, and durability of concrete with recycled plastic fibers., info:eu-repo/semantics/publishedVersion

European Union (EU) aims to achieve nearly zero-energy (public) building (NZEB) by the end of 2018. This very ambitious target would be more easily fulfilled if high- thermal performance materials like phase change materials (PCMs) are to be used. This paper reports experimental results on the mechanical properties of geopolymeric mortars containing PCMs at ambient temperature and after exposure to high temperature. The results show that the inclusion of PCMs is responsible for a reduction of the mechanical strength of the mortars. Several mixtures showed an increase in compressive strength after being exposed to high temperatures. Since PCMs are made of flammable materials, geopolymeric mortars are more advantageous than Portland cement-based mortars for PCM incorporation., info:eu-repo/semantics/publishedVersion

- Abstract
Cost-Effective Energy Efficient Building Retrofitting:Materials, Technologies, Optimization and Case Studies provides essential knowledge for civil engineers, architects, and other professionals working in the field of cost-effective energy efficient building retrofitting. The building sector is responsible for high energy consumption and its global demand is expected to grow as each day there are approximately 200,000 new inhabitants on planet Earth. The majority of electric energy will continue to be generated from the combustion of fossil fuels releasing not only carbon dioxide, but also methane and nitrous oxide. Energy efficiency measures are therefore crucial to reduce greenhouse gas emissions of the building sector. Energy efficient building retrofitting needs to not only be technically feasible, but also economically viable. New building materials and advanced technologies already exist, but the knowledge to integrate all active components is still scarce and far from being widespread among building industry stakeholders. - Emphasizes cost-effective methods for the refurbishment of existing buildings, presenting state-of-the-art technologies - Includes detailed case studies that explain various methods and Net Zero Energy - Explains optimal analysis and prioritization of cost effective strategies

This paper reports experimental results of 32 hybrid cement mixes regarding the joint effect of sodium hydroxide concentration, the use of a commercial superplasticizer and a biopolymer on the flow and compressive strength performance. The results show that the use of commercial admixtures led to a slightly increase in the flow of mortars with lower sodium hydroxide concentration. A mixture based on 80% fly ash, 10% calcium hydroxide and 10% waste glass showed the highest compressive strength. A compressive strength decrease was noticed concerning the use of the two admixtures that can due to the fact that those admixtures are not stable on high basic media., The authors would like to acknowledge the financial support of the Foundation for Science and Technology (FCT) in the frame of project IF/00706/2014-UM.2.15, info:eu-repo/semantics/publishedVersion

The use of bio-based admixtures on construction materials is a recent trend that is gaining momentum. However, to our knowledge, no studies have been reported concerning the use of biopolymers on hybrid cement based mortars. This paper reports experimental results regarding the study of the influence of mix design of 43 hybrid cement mortars containing two different biopolymers on its mechanical performance. The results show that the use of the biopolymer carrageenan is much more effective than the biopolymer xanthan concerning the increase in compressive strength. An optimum biopolymer content was found., {"references":["COM (2011) 571, \"Roadmap to a Resource Efficient Europe, European Commission, Brussels, 2011.","COM (2014) 398 final, \"Towards a circular economy: A zero waste programme for Europe,\" Communication from the Commission to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions.

Waste reuse is crucial in a context of circular economy and zero waste sustainable needs. Some wastes deserve further studies by the scientific community not only because they are generated in high amount but also because they have a low reuse rate. This paper reports results of 32 hybrid cement mortars based on fly ash and waste glass. They allow to explore the influence of mix design on the cost and on the embodied carbon of the hybrid cement mortars. The embodied carbon data for all constituents were taken from the database Ecoinvent. This study led to the development of a mixture with just 70 kg CO2e., {"references":["F. Pacheco-Torgal, J.

In the present study, six different models based on artificial neural networks have been developed to predict the compressive strength of different types of geopolymers. The differences between the models were in the number of neurons in hidden layers and in the method of finalizing the models. Seven independent input parameters that cover the curing time, Ca(OH)2 content, the amount of superplasticizer, NaOH concentration, mold type, geopolymer type and H2O/Na2O molar ratio were considered. For each set of these input variables, the compressive strength of geopolymers was obtained. A total number of 399 input-target pairs were collected from the literature, randomly divided into 279, 60 and 60 data and were trained, validated and tested, respectively. The best performance model was obtained through a network with two hidden layers and absolute fraction of variance of 0.9916, the absolute percentage error of 2.2102 and the root mean square error of 1.4867 in training phase. Additionally, the entire trained, validated and tested network showed a strong potential for predicting the compressive strength of geopolymers with a reasonable performance in the considered range.

- Abstract
This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. - Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders - Considers performance in adverse environmental conditions. - Offers equal emphasis on the science behind the technology and its use in civil engineering.

- Abstract
Climate change is one of the most important environmental problems faced by Planet Earth. The majority of CO2 emissions come from burning fossil fuels for energy production and improvements in energy efficiency shows the greatest potential for any single strategy to abate global greenhouse gas (GHG) emissions from the energy sector. Energy related emissions account for almost 80% of the EU's total greenhouse gas emissions. The building sector is the largest energy user responsible for about 40% of the EU's total final energy consumption. In Europe the number of installed air conditioning systems has increased 500% over the last 20 years, but in that same period energy cooling needs have increased more than 20 times. The increase in energy cooling needs relates to the current higher living and working standards. In urban environments with low outdoor air quality (the general case) this means that in summer-time one cannot count on natural ventilation to reduce cooling needs. Do not forget the synergistic effect between heat waves and air pollution which means that outdoor air quality is worse in the summer aggravating cooling needs. Over the next few years this phenomenon will become much worse because more people will live in cities, more than 2 billion by 2050 and global warming will aggravate cooling needs. - An overview of materials to lessen the impact of urban heat islands - Excellent coverage of building materials to reduce air condtioning needs - Innovative products discussed such as Thermo and Electrochromic materials

Several authors reported a severe reduction in undergraduate applications to civil engineering in different countries. This fact will lead to a severe shortage of civil engineers in the coming years. These professionals will be especially needed to tackle infrastructure construction and rehabilitation on a context of climate change and increased world population. Part of the explanation for the low attraction capability of civil engineering relates to the fact that this course is viewed as low tech. A scientific and technical upgrade of the civil engineering curriculum is, therefore, needed. Nano and biotech based materials and technologies for the built environment could refresh the attraction of this area. The environmental challenges faced by a Planet that has about 220,000 new inhabitants each day and that will have more than 9,7 billion people by 2050 and 11,2 billion by 2100 means that a strong eco-efficiency focus of the new curriculum is also needed. On this context a proposal on a new curriculum on Smart Eco-Efficient Built Environment is suggested that could provide the construction market with professionals with a set of new and enhanced holistic high tech skills., (undefined)

Carbonation is a major cause of concrete structures deterioration leading to expensive maintenance and conservation operations. The eco-efficient construction agenda favours the increase of the use of supplementary cementing materials (SCMs) to reduce Portland cement’s consumption and also the use of recycled aggregates concrete (RAC) in order to reduce the consumption of primary aggregates and to avoid landfill disposal of concrete waste. There is a wide range of literature published on the field of concrete carbonation related to the use of SCMs and/or RCA. However, the different conditions used by different authors limit comparison and in some cases contradictory findings are noticed. Besides, since most investigations are based on the use of the phenolphthalein indicator, which provides a poor estimate of the real concrete carbonation depth, there is a high probability that past researches could have underestimate the corrosion potential associated to concrete carbonation. This paper reviews current knowledge on concrete carbonation addressing carbonation depth’s measurement, the use of SCMs and or RAC.

This paper presents an experimental study to evaluate the influence of physical and geometrical properties of granite and limestone aggregates on the durability of a C20/25 strength class concrete. Different granite and limestone aggregates were collected from seven quarries. Physical, geometrical and mechanical properties of aggregates as well as the rock weathering state were quantify by several tests such as, abrasion, surface hardness, uniaxial compressive strength, ultrasonic pulse velocity, water absorption by capillarity, vacuum water absorption and oxygen permeability. Using aggregates from each quarry, several C20/25 strength class concrete mixes have been produced, with the same workability and volume proportions. Concrete specimens have been cured under water for 90 days; after that time concrete durability parameters were obtained through tests such as, vacuum water absorption, capillarity water absorption, water permeability and oxygen permeability. Relevant statistical correlations have been obtained between absorption and permeability test of rock material and rock deterioration state (weathering). Valid statistic correlation was also obtained between durability parameters as well as among aggregates geometrical properties and concrete durability parameters.

- Abstract
The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste
