Pure-natural pollution-free dry-mixed floor mortar

Abstract

The invention relates to a pure-natural pollution-free dry-mixed floor mortar, which is prepared from the following raw materials in parts by weight: 200 to 250 parts of cement, 710 to 750 parts of yellow sand, 40 to 70 parts of pulverized fuel ash, 0.5 to 2 parts of additive, and 20 to 30 parts of natural thickening agent, wherein the additive is hydroxypropyl methyl cellulose; the natural thickening agent is a mixture prepared from the raw materials in parts by weight: 20 to 30 parts of glutinous rice flour, 15 to 35 parts of egg white powder, 25 to 30 parts of clay soil powder and 15 to 30 parts of straw meal. The pure-natural pollution-free dry-mixed floor mortar has the advantages that the natural thickening agent is adopted, so that on one hand, the overall viscosity of the mortar added with water can be improved, and a series of problems of shrinkage crack, water seepage, sand strip, peeling deformation, low strength level and the like of a surface layer of a floor at the later stage are prevented; on the other hand, the mortar is pollution-free to a human body, and the problem that straw stalks cannot be utilized can be effectively solved; the materials can be effectively smashed through a rotary cutter disc, and a filter effect of a filter box is effectively improved through horizontally swinging the filter box in a reciprocating way.

Description

technical field [0001] The invention relates to the technical field of dry-mixed mortar, in particular to a pure natural and pollution-free dry-mixed ground mortar. Background technique [0002] Dry-mixed mortar is usually called hydraulic cement mixed mortar, which refers to the physical mixing of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened in a certain proportion. It is a granular or powdery material that is transported to the construction site in bags or in bulk, and can be used directly after mixing with water. Also known as mortar dry powder, dry mix, dry mix powder, some construction adhesives also belong to this category. [0003] At present, the existing dry-mixed ground mortar has common problems such as ground sanding, ground hollowing, ground cracking and ground peeling, and due to the lack of thickening agent, the viscosity of the mortar is not high after b...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing dry-mixed ground mortar has common problems such as ground sanding, ground hollowing, ground cracking and ground peeling, and due to the lack of thickening agent, the viscosity of the mortar is not high after being mixed with water on site. The layer is prone to a series of problems such as shrinkage and cracking, water seepage, sand removal, peeling and deformation, and low strength level in the later stage, and the existing thickener contains toxic substances, which is not conducive to human health
