Abstract

The invention discloses mechanized construction plastering mortar and a preparation method thereof. The plastering mortar is formed by mixing powder, aggregate and water, and a mass ratio of the powder, the aggregate and the water is (200-300):(700-800):(160-250); the powder is formed by mixing portland cement clinker, plaster, granulated blast-furnace slag, coal ash, limestone powder and a chemical addition agent, and a mass ratio of the portland cement clinker, the plaster, the granulated blast-furnace slag, the coal ash, the limestone powder and the chemical addition agent is (100-300): (50-100): (50-200): (100-400): (100-400): (2-5). According to the invention, after the detection in a factory according to a quality requirement and the measuring packing, the powder and the aggregate are respectively sent to a construction site or a dedicated distributing bin for burdening, and the mechanized construction is performed; compared with dry-mixed mortar, the aggregate is not required to be dried, so that the drying cost and a part of transportation cost of the aggregate are reduced, and the material cost is substantially lowered; and simultaneously the advantages that the dry-mixed mortar quality can be controlled and the construction site environment is good are maintained.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mechanical construction plastering mortar and a preparation method thereof. Background technique [0002] Architectural plastering mortar is mainly used for plastering indoor and outdoor walls of buildings, the purpose is to protect the base layer of the wall and increase the aesthetic effect. At present, there are two main types of building plastering mortar: the first type is dry-mixed mortar, that is, the aggregate (also called sand) is dried in the factory and mixed with cementitious materials (including cement, fly ash) and chemical admixtures After mixing in proportion, it is transported (filled or bagged) to the construction site, where it is directly mixed with water to form a plastering mortar; the second type transports cement (usually in bags) and wet sand to the construction site separately, and manually weighs the materials on the constructio...
