Contributor Van Breugel, K. (promotor) Haas, E.M. (promotor) Ye, G. (promotor) Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2013-06-20 Abstract Concrete is one of the most important construction materials in the world. However, Portland cement which is one of the constituents of concrete is responsible for about 5-10% of global CO2 emission. From sustainability point of view, therefore, it is important to search for materials which can be used to reduce or to replace Portland cement in concrete. Among the mineral admixtures micronized sand with high purity SiO2 has been selected as cement replacement. Micronized sand is produced by grinding of quartz sand, which is the most abundant mineral in the earth’s crust. Therefore, the use of this material will not cause a depletion of resources. The objective of this research is to investigate the possibility of using micronized sand to partially replacement cement in concrete. The performance of cement-based material with micronized sand as partial replacement of cement was evaluated with respect to the microstructure, durability and sustainability both experimentally and by numerical simulations.
