Admixtures composition and mortar and concrete composition for revealing high early strength including the same

摘要

The present invention relates to a) admixture, and b) the admixture composition comprising sodium sulfate and frustrating steel mortar, concrete compositions containing them. Frustrating steel mortar, concrete admixture composition comprising the composition according to the invention, and it is possible to shorten the initial cure time while maintaining the physical properties of the mortar or concrete at. And also to facilitate the mixing of the blast furnace slag to be added or fly ash and cement, early strength does not fall easily. In addition, is expected to be sufficient to complement the disadvantages of the concrete or mortar can be improved by lowering the physical properties of the water content of the concrete or mortar, including conventional blast furnace slag or fly ash.
