Manufacturing method of waterproofing agent for concrete with excellent waterproofing

摘要

The present invention relates to a method for producing a waterproof cement composition containing a natural zeolite, more specifically, 65-85 parts of Portland cement, 10-18 parts of cemented carbide, 1-2 parts of calcium chloride, sodium silicate 1 -4 parts, 2-8 parts of natural zeolite is added to 1-3 parts of sodium hydroxide, and then mixed and pulverized while drying with a warm air in a pot mill to obtain water absorption and adsorption characteristics It provides a waterproof cement composition having excellent waterproof properties by synergy such as strength improvement and watertightness improvement by the porous crystal structure, which is a physical property, and this composition is used by adding 100-200 parts by weight of water and kneading uniformly, It is particularly beneficial for the waterproofing of concrete block structures.
