Abstract: Since the ultimate porosity, and consequently the durability, of concrete is not only determined by the microstructural built-up, but also by the formation of (micro)cracks in the cement matrix caused by the differential shrinkage of the composing phases in the concrete matrix, a study of the microstructural built-up and the formation of (micro)cracks during hardening and curing is inevitable when dealing with durability of cementitious materials.
For this reason, the influence of mineral additions and chemical admixtures in SCC on microcracking and durability are studied in the Belgian research project G.0311.06, sponsored by the Research Programme of the Research Foundation - Flanders (FWO).
The research project is a cooperation between the Reyntjens Laboratory (K.U.Leuven), the Magnel Laboratory for Concrete Research (Ghent University) and the Royal Military Academy Brussels.
The main objectives of the ongoing research project are: (1) determination of the influence of the different parameters on the formation of microcracks; (2) determination of the influence of these parameters on the microstructural built-up and (3) formulation of porosity and flow models which simulate the durability behaviour of SCC. An overview of the research project is presented.
