The effects of sand concentration and porosity on the elastic properties of mortar and cement paste were studied. Acoustic wave measurements were performed on mortar specimens with 0 to 60 percent sand concentration, and on cement paste specimens with 28 to 53 percent porosity. The experimental resu
Effects of alumino-silicate clays on fracture properties of cement-based materials are reported in this paper. Two clays, illite and kaolinite, were used to replace 20% of Type I portland cement in different mixtures. Pores size distributions of hardened specimens were measured using mercury intrusi
