Rocky sand crystal

Abstract

A rock sand crystal instead of lime or cement in mortar is prepared from emtrol sodium polyvinylsulfonate, sodium abietate, triisopropanol amine, polyacrylate, sodium sulfate and powdered coal ash.

Description

technical field [0001] The invention belongs to the field of building material admixtures, in particular to a rock sand crystal used for mixing mortar. Background technique [0002] In the history of Chinese architecture, the use of lime has a history of thousands of years. As the world's awareness of environmental protection increases, it is recognized that the use of lime destroys the ecological environment, and sintering of lime causes environmental pollution. In the 1990s, China began to study the admixture called "micro-membrane agent" to replace lime. After being used in construction mixed mortar to replace lime, the workability was improved and the use effect was ideal. However, as time went by, "micro-membrane" "Agent" can reduce the plastic strength of mortar. Practice has proved that "micro-membrane agent" is not the best white ash substitute product. In 2000, the use of "micro-membrane agent" has been stopped in this part of the area. And during this period, so...
