Performance of crystalline forming additive materials in ...

This paper addresses the performance of crystalline forming additive materials in terms of morphology characterization and water Sorptivity. Three different water-cement ratios of concrete; namely, 0.6, 0.5 and 0.387 have been considered to cover the range of concrete mixtures from highly to low permeable concrete.
