Mortar for building and plastering PTB aerated concrete blocks and using method thereof

Abstract

The invention provides mortar for building and plastering PTB aerated concrete blocks, which belongs to the technical field of building materials. Raw materials of the mortar are PTB aqueous solution and PTB powder, wherein the PTB aqueous solution is prepared by diluting PTB emulsion (COMPAKTUNA PRO) and water in a certain proportion; and the PTB powder comprises waste PTB aerated concrete blocks. The PTB aqueous solution and the PTB powder are stirred uniformly to form the mortar for building and plastering the PTB aerated concrete blocks. The mortar has good cohesiveness, water resistance, water retention and deformation capacity, comprehensively uses the waste aerated concrete blocks, has significant environmental protection benefit, is suitable for large-scale popularization and application, and has significant economic benefit.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically relates to a PTB aerated concrete block masonry and plastering mortar and a use method thereof. Background technique [0002] The autoclaved products of aerated concrete are made of calcareous materials and siliceous materials (fly ash, slag, sand, etc.) It is a man-made new wall material made under high temperature and high pressure conditions by a certain production process. Due to the objective factors such as large drying shrinkage rate, poor moisture conductivity, long dehumidification time, and elastic modulus smaller than ordinary masonry mortar and plastering mortar, aerated concrete blocks are prone to wall cracks. Many experts at home and abroad have done a lot of research on it, but the problem of cracks in the walls of aerated concrete blocks has not been effectively solved. And many aerated concrete block manufacturers produce a lot of aerated concr...

Due to the objective factors such as large drying shrinkage rate, poor moisture conductivity, long dehumidification time, and elastic modulus smaller than ordinary masonry mortar and plastering mortar, aerated concrete blocks are prone to wall cracks

Many experts at home and abroad have conducted a lot of research on it, but the problem of cracks in the walls of aerated concrete blocks has not been effectively solved

And many aerated concrete block manufacturers produce a lot of aerated concrete block waste (including unqualified aerated concrete blocks, aerated concrete block scraps, etc.) in the production process, causing environmental pollution and waste of resources
