A plastering anti-cracking mortar dry powder based on autoclaved sand aerated concrete waste

Abstract

The invention relates to plastering anti-cracking mortar dry powder based on autoclaved sand aerated concrete waste. The plastering anti-cracking mortar dry powder comprises 40-65 parts of autoclaved sand aerated concrete waste, 35-60 parts of cement, 0.07-0.1 part of methyl cellulose, 0.1-0.25 part of glue powder, 0.03-0.1 part of anti-cracking fiber and 0.01-0.02 part of an additive. According to the plastering anti-cracking mortar dry powder, the autoclaved sand aerated concrete waste is firstly utilized to prepare the plastering anti-cracking mortar dry powder, the cost of the mortar dry powder is effectively reduced, and a developed product can be used as a self-heat insulation raw material of a wall body for locally matching with a building for use, so that resources are saved, the waste is turned into treasure and the development of energy-saving work of the building can be promoted; furthermore, a preparation method of the dry powder has the advantages of simplicity, no secondary pollution and a wide range of raw material sources, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a plastering anti-cracking mortar dry powder, in particular to a low-cost plastering anti-cracking mortar dry powder prepared by using autoclaved sand aerated concrete waste. Background technique [0002] Autoclaved sand aerated concrete is a new type of building wall material with wall self-insulation. Its technology began a hundred years ago. It mainly uses cement, lime, gypsum, aluminum powder and sand as raw materials. After raw material preparation, batching and pouring , Static curing to generate gas, green body cutting, autoclaved curing, finished product storage and other processes. The biggest advantage of autoclaved sand aerated concrete is that it saves land resources and does not need to waste a lot of arable land. The source of raw materials is very extensive; and it has very good machinability, heat insulation, heat preservation capabilities and processing characteristics, and can be sawed or sawed. With the cont...
