CONCRETE ADMIXTURE FOR MINIMIZATION OF HEXAVALENT CHROMIUM IN CONCRETE AND CONSTRUCTION METHOD USING THE SAME

摘要

The present invention relates to a concrete admixture which is added to a final cement product by substituting a certain portion, and to a concrete construction method using the same. More specifically, the present invention aims to provide the concrete admixture capable of reducing precipitation of water-soluble and acid-soluble hexavalent chromium ions using active loess activated to increase activity of a pozzolan reaction; and the concrete construction method using the same. For such, the concrete admixture is inserted into concrete to reduce precipitation of hexavalent chromium, and is a loess-based material activated to increase the pozzolan reaction. According to the concrete construction method, the cement, the loess-based admixture, an aggregate material, and water are mixed to be applied in the construction.
