High-performance aerated concrete plastering mortar

Abstract

The invention relates to the field of building materials, in particular to high-performance aerated concrete plastering mortar which is characterized by comprising the following materials in parts by weight: 250-350 parts of cement, 80-120 parts of floating beads, 40-80 parts of reinforced material, 70-90 parts of composite heat insulation aggregate, 1-2 parts of short fiber, 0.2-1.5 parts of water reducing agent, 0.5-2.0 parts of thickening agent, 5-10 parts of redispersable powder and 300-400 parts of slag sand. Compared with the prior art, the invention can effectively save the use of materials such as cement and the like, simultaneously enables the mortar to have excellent water conserving performance, crack resistance, water resistance, fire resistance and the like and excellent bonding force and anti-sagging performance, prevents the phenomena of hollowing and cracking from occurring, meets all performance requirements of a plastering layer, and has the obvious advantages of energy saving, environmental protection, simple construction, high strength, low cost, good product quality and the like.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a high-performance aerated concrete plastering mortar. Background technique: [0002] As we all know, building energy efficiency is one of the ultimate goals of the basic national policy to realize the sustainable development of resources in China. According to statistics, the energy consumption per unit building area in China is as high as 3 times that of developed countries with similar climatic conditions. 95% of the buildings in China are high-energy buildings. Reducing the heat transfer coefficient of the building envelope is a major measure and effective means for building energy saving. As a new wall material, aerated concrete is a kind of siliceous material. (Sand, floating beads and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with a gas generating agent (aluminum powder), through the ingredients, mixing, pouring...

Problems solved by technology

Since the external wall thermal insulation system is a thermal insulation system installed on the surface of the building's external wall, its environmental conditions are relatively complex, and the weather resistance conditions are relatively high. However, in the application process of new wall materials and external thermal insulation technology Due to the lack of special masonry and plastering mortar for aerated concrete, construction units often use ordinary cement mortar for masonry and plastering, which has caused many engineering buildings to have problems such as wall cracking, hollowing, and leakage, which have seriously affected The effective development of building energy saving has brought inconvenience to people's production and life, so there is an urgent need for a mixed plastering mortar with good energy saving effect, simple construction and superior quality
