In this paper, phosphogypsum-based polymer foam lightweight soil was prepared by taking phosphogypsum as fine aggregate and adding coagulant and prefabricated foam. The changes in the properties of the material were studied deeply in terms of flow rate, setting time, mechanical properties, water absorption and softening coefficient, combined with XRD and SEM for microscopic testing. The results show that mortar test blocks with excellent performance can be prepared under the conditions of sand-to-ash ratio 0.6, water-to-material ratio 0.5 and quicklime 4%. The initial and final setting times are 210 and 260 minutes, the compressive strength of the specimen can reach 2.8 MPa after 3 days, and 11.9 MPa after 28 days. Foam lightweight soil with different wet density can be prepared by adjusting the amount of prefabricated foam, providing a new way for phosphogypsum resource application. [ABSTRACT FROM AUTHOR]

Photovoltaic silver paste is an indispensable core component in solar cells, which directly limited the performance of solar cells by its quality. The series of properties improvement including conductivity, flexural resistance, adhesion and welding tension become an important development direction in the future. In this stage, the raw materials silver powder should demonstrate better dispersion and particle size uniformity, as well as the resin should possess better adhesion to provide good skeleton support. The core of excellent silver paste lies in the selection and allocation of formula raw materials. In recent years, the silver paste recipe exhibited short development cycle and renewal rate, which puts forward higher requirements for research. Therefore, this paper summarizes three main factors affecting the performance of silver paste, including: 1) the effect of silver powder on the performance; 2) influence of resin bonding relative properties; 3) the effect of solvent on the performance of silver paste. Meanwhile, the key technology of photovoltaic silver paste is expounded to provide some guidance for developing and optimizing the recipe of photovoltaic silver paste. [ABSTRACT FROM AUTHOR]

Silver-based electrical contact material is core component to ensure low-voltage apparatus efficient and safe operation. The performance specifications directly affect the safety and reliability of electrical equipment. On account of environment protection, traditional silver cadmium oxide electrical contact material containing cadmium, a heavy metal toxic element, is being phased out of existence. With the updating and upgrading of low voltage electrical equipment, higher performance requirements are proposed for silver-based electrical contact materials. In this paper, the failure mechanism of silver based electrical contact materials and the classification of common silver based electrical contact materials are discussed. At the same time, the existing problems, composition design and process optimization of various silver based electrical contact materials are comprehensively summarized. In combination with the research and development needs of various low-voltage apparatus efficients, suggestions for the development of silver based electrical contact materials in the future are given, which provides reference for the research and development of silver based electrical contact materials.

Geopolymer not only possesses the combined excellent properties of organic polymer materials, ceramic materials and cement materials, but also has many advantages such as low production energy consumption and carbon emissions, wide raw material source, and excessive consumption of solid wastes. Therefore, it has rapidly become a research hotspot in the field of inorganic cementitious material in recent years. After introducing the calcium component into geopolymer system, the interaction processes among the main gel phases may become more complicated. Moreover, microstructure and the main performance of geopolymer may be greatly affected. In this paper, we systematically review the research developments in Ca_containing geopolymer, with a particular summary and analysis on the way of introducing calcium component during geopolymer preparing process, as well as the influence rule and action mechanism of calcium component on microstructure and performance (including setting time, compressive strength, solidification/stabilization of heavy metals, resistance to chemical attack, al kali - aggregate reaction, thermal stability, and resistance to efflorescence) of geopolymer. Tt would provide technical reference for performance control and application study of C

Chloride penetration is the main reason for corrosion of steel bars in reinforced concrete in marine environment, salt lake area and saline soil area. Therefore, the measurement of chloride distribution in reinforced concrete structures timely and accurately is of great significance for durability assessment, maintenance and repair of reinforced concrete structures under severe environment. In this paper, a solid-state Mn/MnO2 reference electrode with dense structure and stable performance, which can be embedded in concrete, was prepared by pressed powder method. Results showed that loading pressure is an important parameter that affects the strength and density of Mn/MnO2 electrode prepared. During the preparation of Mn/MnO2 electrode, it is necessary to control the loading pressure. The suggested pressure loading pressure is 96 MPa. And the Mn/MnO2 electrode must be activated before use. After activated, the response time of the Mn/MnO2 electrode is less than 60 second. Also, the Mn/MnO2 electrode has stable performance, good reproducibility and good resistance of polarization. The potential value of the Mn/MnO2 electrode increases linearly with the increase of temperature between 5 °C and 65 °C. Besides, the pH value between 8 and 13 has nearly no effect on the potential value of the Mn/MnO2 electrode. So, if the Mn/MnO2 electrode prepared in this paper is used as reference electrode of chloride sensor, the temperature of concrete at the location of chloride sensor is also needed to record simultaneously. And the potential value of the Mn/MnO electrode must be corrected by temperature. [ABSTRACT FROM AUTHOR]

This paper aimed to conduct systematic bibliometric and visual analysis of graphene oxide（GO） status, and to explore the development status, research hotspots and frontier trends. CNKI database was used as the data source to retrieve the literature related to GO, and the bibliometric method was used for statistical analysis. A total of 2728 articles were included in this study, and the relevant studies showed a trend of “rising-slow decline”. The institutions with relatively high literature output are science and engineering colleges, indicating that the degree of specialization and intensification in this research field is relatively high. The keywords formed five categories, which were clustered by basic research on GO, preparation and reduction of GO, photocatalytic performance, electrochemical performance and mechanical properties, and made full use of GO characteristic analysis to describe the research hotspots in this field. The frontiers of GO research include： finding more ways to synthesize polymers and GO to improve the electrochemical performance of composites, GO composites adsorbing pollutants for sewage treatment, and using electrochemical reduction to prepare graphene using GO. GO has been widely used and has excellent performance in recent years, which is worthy of further exploration by relevant researchers to expand its application in the field of environment and chemistry [ABSTRACT FROM AUTHOR]

The expansion, compressive strength and pore structure of concrete containing MEA were investigated in this paper. Furthermore, the hydration degree of MEA with different activities were quantitatively analyzed by QXRD. The results showed that in natural condition, the deformation of concrete containing MEA was evidently lager than reference, and the higher the activity, the lager the deformation. The shrinkage deformation of reference concrete at 180d was -157 µε, while the expansion deformation of concrete containing 6% MEA-120s,MEA-210s and MEA-260s were 193 µε,98 µε and 93 µε, respectively. Compared with reference, the compressive strength of concrete containing 6% MEA-120s was increased by 6%, and the total porosity of concrete containing 6% MEA-120s, MEA-210s and MEA-260s at 60d were reduced by 20%, 10% and 8%. MEA could efficiently improve the pore structure of concrete, decrease the total porosity, and thus enhance the compressive strength. In natural curing condition, the temperature and relative humidity had a significant effect on the hydration of MEA, the hydration degree of MEA-120s, MEA-210s and MEA-260s at 180d were 78%, 66% and 52%.
