Abstract

The invention relates to plastering mortar and a preparation method thereof. The mortar is prepared from the following components in parts by weight: 170 to 290 parts of cement, 70 to 80 parts of flyash, 630 to 760 parts of dry sand, 0.8 to 1.5 parts of cellulose ether, 0.2 to 0.8 part of starch ether and 0.02 to 0.07 part of an air entraining agent, wherein the dry sand is machine-made sand withthe size of 40 to 140 meshes. According to the plastering mortar, the machine-made sand is used as a fine aggregate component of the thin-layer plastering mortar; the requirements of the mortar on natural sand are reduced on the basis of ensuring all properties of the plastering mortar and the pressure on environmental resources is alleviated.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a plastering mortar and a preparation method thereof. Background technique [0002] Plastering mortar is a decorative project that is applied on the walls, roofs, floors, columns and other surfaces of buildings and directly made into a finishing layer. It can not only protect the base layer, increase the appearance, but also provide special functions for the building. Thin-layer plastering mortar refers to the plastering mortar whose thickness of the mortar layer is not more than 5mm. Compared with ordinary plastering mortar, the construction is relatively simple, but the water retention rate of thin-layer plastering mortar is not less than 99%, and the viscosity is high. [0003] Dry-mixed mortar is a powder mixture made by uniformly mixing cementitious materials, fine aggregates, mineral admixtures, admixtures and other components in a certain proportion. It needs...
