Novel dry-blending plastering mortar

Abstract

The invention discloses novel dry-blending plastering mortar. The novel dry-blending plastering mortar is prepared from, by weight, 150 parts of cement, 8 parts of thickening powder, 82 parts of stonepowder and 790 parts of machine-made sand. The novel dry-blending plastering mortar is stable in fineness modulus, the cost is saved, the tailings resource is effectively utilized, and the hollowingphenomenon of a wall surface is reduced.

Description

Technical field: [0001] The invention relates to the field of mortar, in particular to a novel dry-mixed plastering mortar. Background technique: [0002] The existing plastering mortar usually uses natural sand and fly ash as aggregates, but the fineness modulus and gradation of natural sand fluctuate greatly, and the natural sand contains mud content, which affects the firmness, and the wet sand needs to be dried , the cost is high; and the plastering mortar used for natural sand has some hollowing and cracking phenomenon, and the drying temperature of natural sand is between 75-85 °C, the temperature of the mortar is high during the continuous shipment, and in the process of bulk truck feeding The higher the temperature, the greater the water demand for the mortar. Another point is that natural sand is prohibited from being mined due to rivers and rivers, resulting in a shortage of resources. Invention content: [0003] The technical problem to be solved by the present...
