Abstract:In order to develop a chemical admixture which improves durability of concrete, we have experimentally made two types of hybrid admixtures combining a single-liquid type, high-range, water-reducing admixture with a shrinkage-reducing admixture, and examined their concrete properties, ranging from normal - to ultrahigh-strength.
Hybrid admixture, HSP1, for normal-strength concrete, showed reduced drying
shrinkage of approximately 15 % and HSP2, for high-strength concrete, showed an autogenous shrinkage reducing ability of approximately 20~35 %. Also, both showed sufficient resistance to frost damage and carbonation.
