CONCRETE ADMIXTURE, MORTAR ADMIXTURE AND BLENDED CEMENT

摘要

PROBLEM TO BE SOLVED: To obtain an admixture for improving the tensile strength of concrete and mortar.;SOLUTION: A concrete admixture or a mortar admixture is prepared by mixing a silicate with an acid in the presence of water and then solidifying the mixture. In such a case, it is preferable that the silicate is sodium silicate and the acid is a carboxylic acid. Since the concrete or the mortar composed of the admixture, cement, an aggregate and water has high tensile strength, it can advantageously be used in various kinds of concrete structures, concrete products or mortar products.;COPYRIGHT: (C)2004,JPO
