ADMIXTURE FOR IMPROVING WATER-TIGHTNESS AND DURABILITY OF CONCRETE AND MORTAR

摘要

PURPOSE:To provide an admixture for concrete and mortar capable of promoting the hydration reaction of cement in concrete or mortar, imparting water- retainability to improve the water-tightness of concrete and mortar even in the case of concreting in site impossible to perform sufficient curing of concrete after placing, forming an insoluble and corrosion-proofing substance to inhibit the permeation of corrosive substances such as carbon dioxide gas and acidic rain and improving the durability of concrete and mortar. CONSTITUTION:The admixture is a composition composed of calcium nitrite, copper lactate, glycerol, sodium lactate and di-n-butoxybistitanium.
