Problems solved by technology

[0002] The aerated concrete blocks and autoclaved fly ash bricks that are often used in the construction industry are still built and plastered with traditional cement mortar because there is no special mortar with low price and superior performance, which leads to cracking of the wall and plastering. The cracking or even falling off of the hollow layer occurs from time to time, which seriously affects the promotion of new wall materials and the quality of construction projects

Abstract

Disclosed is a dedicated mortar for steaming and pressing fly ash brick and aerated concrete building block which comprises gypsum 30-40%, comprising silicate cement 15-25%, coal ash 45-55%, water-retaining and thickening agent 0.1-0.4%, redispersable rubber powder 2-4%, crack resistant fiber 0.1-15%, wherein the content of the coal ash exciting agent is 2-4% of the total coal ash amount.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a special mortar. Background technique [0002] The aerated concrete blocks and autoclaved fly ash bricks that are often used in the construction industry are still built and plastered with traditional cement mortar because there is no special mortar with low price and superior performance, which leads to cracking of the wall and plastering. The phenomenon of cracking or even falling off of the hollow layer occurs from time to time, which seriously affects the promotion of new wall materials and the quality of construction projects. Contents of the invention [0003] The purpose of this invention is to provide a new type of special mortar for autoclaved fly ash bricks and aerated concrete blocks, thereby reducing costs, making the material of the adhesive mortar similar to that of aerated fly ash blocks, synchronizing shrinkage...
