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 co ...
The use of cement and concrete, among the most widely used man-made materials, is under scrutiny. Owing to their large-scale use, production of cement and concrete results in substantial emission of greenhouse gases and places strain on the availability of ...
The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
By studying approximately a century of cement and concrete in Switzerland, this project examines the relations between institutions, discourse, and technology as they intersect in the material. The project is framed so that the establishment of organizatio ...
The development of Ultra-High Performance Concrete (UHPC) opened new research directions for enhancing the architectural design, sustainability and serviceability of concrete structures. However, the costs and resource intensiveness trigger the need for in ...
The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages.Alite is the main constituent of Portland Cement (PC), and is responsible ...
Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...
This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...
Alkali-silica reaction (ASR) is a concrete disease that leads to its degradation. ASR is the reaction between the amorphous silica (SiO2 ) and the alkali ions (Na + , K + ), leading to expansion of concrete in presence of Ca 2+ . In this study, it is assum ...
The design of RC members with nontraditional methods is demanding due to the large number of unknown variables inherent in the design process. The complexity of the RC beam design optimization problem has led to many oversimplified models, so that the curr ...
