Abstract

Die Arbeit liefert einen Beitrag zum Verständnis der bei Carbonatisierung ablaufenden chemischen und physikalischen Prozesse. Der beschleunigende Einfluss eines erhöhten Gasdrucks auf die Carbonatisierung konnte nachgewiesen werden und ist ein sinnvolles Vorgehen, um unterschiedliche zementgebundene Materialien bzgl. ihres Carbonati¬sierungs¬widerstands effizient zu bewerten. Hierbei erweisen sich geringe Drücke bis 5 barg und relative Luftfeuchtigkeit von 50 - 65 % RH besonders effektiv., The main contributions of this thesis are an advanced understanding of carbonation and a new approach to test carbonation resistance of cementitious materials by applying increased gas pressure at relative humidities of 50 - 65 %.

Abstract

The expected lifespan of cement-based materials, particularly concrete, is at least 50 years. Changes in the pore structure of the material need to be considered due to external influences and associated transport processes. The expansion behaviour of concrete and mortar during freeze–thaw attacks, combined with de-icing salt agents, is crucial for both internal and external damage. It is essential to determine and simulate the expansion behaviour of these materials in the laboratory, as well as detect the slow, long-term expansion in real structures. This study measures the expansion of mortar samples during freeze–thaw loading using a high-resolution hand-held 3D laser scanner. The specimens are prepared with fully or partially saturated pore structures through water storage or drying. During freeze–thaw experiments, the specimens are exposed to pure water or a 3% sodium chloride solution (NaCl). Results show contraction during freezing and subsequent expansion during thawing. Both test solutions exhibit similar expansion behaviour, with differences primarily due to saturation levels. Further investigations are required to explore the changing expansion behaviour caused by increasing microcracking resulting from continuous freeze–thaw cycles. A numerical analysis using a 3D coupled hygro-thermo-mechanical (HTM) model is conducted to examine the freeze–thaw behaviour of the mortar. The model accurately represents the freezing deformation during the freeze–thaw cycle. [ABSTRACT FROM AUTHOR]

Abstract

Blended cements, where Portland cement clinker is partially replaced by supplementary cementitious materials (SCMs), provide the most feasible route for reducing carbon dioxide emissions associated with concrete production. However, lowering the clinker content can lead to an increasing risk of neutralisation of the concrete pore solution and potential reinforcement corrosion due to carbonation. carbonation of concrete with SCMs differs from carbonation of concrete solely based on Portland cement (PC). This is a consequence of the differences in the hydrate phase assemblage and pore solution chemistry, as well as the pore structure and transport properties, when varying the binder composition, age and curing conditions of the concretes. The carbonation mechanism and kinetics also depend on the saturation degree of the concrete and CO2 partial pressure which in turn depends on exposure conditions (e.g. relative humidity, volume, and duration of water in contact with the concrete surface and temperature conditions). This in turn influence the microstructural changes identified upon carbonation. This literature review, prepared by members of RILEM technical committee 281-CCC carbonation of concrete with supplementary cementitious materials, working groups 1 and 2, elucidates the effect of numerous SCM characteristics, exposure environments and curing conditions on the carbonation mechanism, kinetics and structural alterations in cementitious systems containing SCMs., Accepted author manuscript, Corrigenda DOI: 10.1617/s11527-020-01599-1 and DOI:10.1617/s11527-021-01658-1, Materials and Environment
