摘要: With the increasing use of self-compacting concrete (SCC) its durability has come into focus. Concerning microstructure concrete, porosity in interfacial transition zone (ITZ) is regarded as a key feature for permeability and durability. Generally, combination cement mineral admixtures used production SCC. In present study, ITZ four SCC mixtures produced with ordinary Portland cement, limestone slag combined fly ash analyzed. Additionally, chloride migration coefficient determined. width are similar. The substantial differences coefficients show that binder type stronger influence on than pore volume ITZ.
