The Crystalline Admixture Effect on Concrete and Cement Mortar Compressive Strength

Abstract:

There have been many experimental measurements of the waterproofing ability of concrete with a crystalline admixture. For the comprehensive evaluation of crystalline admixtures, it is necessary to consider their effect on the compressive strength of concrete f_ck, not only their waterproofing ability. The paper describes laboratory testing which subject was the selected crystalline admixtures effect on the compressive strength of concrete f_ck. The results have shown that the compressive strength f_ck,cube of concrete with a crystalline admixture (added in an amount of 2%) was almost identical to the specimens from concrete without admixture after 28 days. The compressive strength of the next specimens from cement mortar with a smaller amount of a crystalline admixture (1%) after the 28 days was higher than the strength of the specimens without admixtures.
