Abstract

The invention relates to an anti-cracking anti-seepage dry-mixed plastering mortar dry-mixed material and plastering mortar, and belongs to the technical field of building materials. The dry-mixed material is prepared from the following raw materials, in parts by weight: 120-140 parts of cement, 33-83.5 parts of an admixture, 820-840 parts of medium sand, 35-45 parts of recycled powder, and 1-16.6 parts of an additive, wherein the admixture comprises at least two selected from the group consisting of fly ash, metakaolin, phosphorus slag, silica fume and magnesium slag, the recycled powder is dust particles recovered in the process of producing dry-mixed plastering mortar and comprises stone powder, cement and an admixture, and the additive comprises at least one selected from acrylic latex powder and lignin fiber and a plasticizer. The dry-mixed material and the plastering mortar provided by the invention have the effects of good bonding strength, cracking resistance and seepage resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, it relates to an anti-crack and anti-seepage dry-mixed plastering mortar dry mix and plastering mortar. Background technique [0002] Plastering mortar is a kind of building mortar that can be applied on the building surface to level or meet the requirements of decoration and decoration. Dry-mixed plastering mortar is based on cement as the main bonding base material, together with river sand, admixtures, and admixtures. After weighing the ingredients and mixing them evenly, you only need to add water on the construction site and stir them before using. With the advancement and development of grass-roots construction and urbanization, the demand for plastering mortar is also increasing. The annual use of mortar in the world has exceeded 200 million tons, but in the actual use of plastering mortar, there are still problems. Cracking, hollowing, peeling and other qual...
