COLD-RESISTANT ADMIXTURE FOR EARLY STRENGTH-TYPE CEMENT FOR USE IN WINTER TIME

摘要

The present invention relates to a cold-resistant admixture for early strength-type cement for use in winter time. Specifically, the cold-resistant admixture comprises: a first admixture to improve flowability and retention properties of cement; and a second admixture which is mixed with the first admixture prior to use to express and enhance early strength of cement, wherein the first admixture and the second admixture are combined with early strength-type cement and an anti-freezing agent prior to use. Accordingly, by combining a liquid admixture for improving flowability and retention properties of cement and a powder admixture for expressing and enhancing early strength of cement with early strength-type cement and an anti-freezing agent, the cold-resistant admixture of the present invention ensures early flowability and retention, and thus prevents slump loss and enhances early compressive strength.;COPYRIGHT KIPO 2018
