An aqueous chemical mixture to mitigate problems associated with water in concrete pavements

摘要

A method for preparing an aqueous mixture comprising at least 50% by weight of water for application to concrete floors for protection against problems associated with water, comprising: (1) forming a diluted mixture of at least one surfactant and emulsifier ; (2) gradually add sodium silicate to water in a reactor and mix; (3) gradually add the surfactant / emulsifier mixture to the sodium silicate mixture; (4) add tartaric acid to water in small portions at a time, while stirring continuously; (5) add sodium carbonate in small portions each time to the tartaric acid mixture; (6) gradually add the sodium surfactant / emulsifier / silicate mixture to the tartaric acid / sodium carbonate mixture; (7) Slowly introduce potassium methylsiliconate into the mixture of surfactant / emulsifier / sodium silicate / tartaric acid / sodium carbonate and mix; and (8) allow the material to stand for approximately one hour while it is covered before entering into containers; Therefore, a container maintained above 10 degrees C has a shelf life of at least six months.
