Wet-mixed masonry coating plaster

Abstract

The invention discloses thin mortar joint masonry thin layer plastering special for buildings and in particular relates to wet-mixed masonry coating plaster prepared by taking acetylene sludge and pulverized coal ash as main raw materials. The wet-mixed masonry coating plaster is composed of the following raw materials in percentage: acetylene sludge, pulverized coal ash, complex liquid, a deodorant, polycarboxylate superplasticizer and staple fibers. The wet-mixed masonry coating plaster disclosed by the invention refers to thin mortar joint masonry plaster for aerated concrete blocks and foamed concrete blocks and thin foam ash plaster for buildings. According to the wet-mixed masonry coating plaster, industrial wastes acetylene sludge and pulverized coal ash are changed into valuable materials, the wet-mixed masonry coating plaster is low in manufacturing cost and can be popularized in a large area, the mechanical property is matched with that of the aerated concrete blocks, the thermal insulation properties are excellent, the wall surface does not need to be watered during construction, only capping mass on the old wall surface needs to be removed, and the masonry coating thickness is 3-5mm. Compared with the traditional mortar with the masonry coating thickness of 2cm, the wet-mixed masonry coating plaster disclosed by the invention is high in working efficiency, rapid in construction and capable of saving materials, can achieve excellent gas permeability and is a revolutionary transformed environment-friendly material.

Description

technical field [0001] The invention relates to building materials, and is a thin plaster for thin mortar seam masonry special for buildings, in particular to a wet-mixed plastering paste prepared from calcium carbide slag and fly ash slag as main raw materials. Background technique [0002] With the continuous advancement of building a conservation-oriented society, it is very important to promote the development, demonstration and promotion of resource-saving technologies. In terms of construction, most of the masonry mortars we use in aerated concrete blocks and foam concrete blocks still use traditional Cement mortar and dry-mixed dry-mixed mortar, but they have not been widely used due to high cost.

[0002] With the continuous advancement of building a conservation-oriented society, it is very important to promote the development, demonstration and promotion of resource-saving technologies. In terms of construction, most of the masonry mortars we use in aerated concrete blocks and foam concrete blocks still use traditional Cement mortar and dry-mixed dry-mixed mortar, but they have not been widely used due to high cost. The thermal conductivity of traditional cement mortar and dry-mixed dry-mixed mortar is much higher than that of aerated concrete blocks and foam concrete blocks. The thermal bridge and cold bridge increase energy consumption, and the self-insulation effect cannot be completely completed, and the traditional cement mortar and dry-mixed dry powder mortar are used for plastering the wall surface and need to be hung with nets and not breathable. The mortar coating is thick during construction, and the construction period is long. Long, inconsistent with my country's basic national policy of building a conservation-minded society and sustainable development
