Abstract

The invention belongs to the field of mortar and specifically discloses veneer mortar, a preparation method and a use method thereof. The mortar comprises the following raw materials in parts by weight: 140-170 parts of cement, 70-80 parts of superfine slag powder, 20-30 parts of coal ash, 40-50 parts of sulfur-fixing ash, 600-700 parts of quartz sand, 10-20 parts of emulsion powder, 0.1-0.3 partof water-retaining agent, 2-4 parts of a water reducer, 2-4 parts of a water repellent, 1-1.5 parts of a de-foaming agent and 3-5 parts of pigment. The preparation method for the veneer mortar comprises the following steps: accurately weighting the raw materials by weight ratio, putting the raw materials into a dry mixing device and then mechanically and uniformly stirring, thereby acquiring a required product. The veneer mortar provided by the invention has excellent overall performances and can solve the problems of resource shortage of traditional cement admixtures, such as superfine slag powder and coal ash, limited recycling ways and low use ratio of sulfur-fixing ash.

Description

technical field

[0001] The invention belongs to the field of mortar, and specifically discloses a facing mortar and a preparation method thereof. Background technique

[0002] Finishing mortar is a kind of inorganic mineral mortar, mainly composed of cementitious material, graded sand, filler, pigment and admixture, etc. It has rich shapes and wide range of color changes, and is widely used in interior and exterior wall decoration of buildings. . At present, in the preparation technology of facing mortar, industrial solid wastes such as slag powder and fly ash are often used as cement admixtures, compounded with ordinary Portland cement in a certain proportion and then used as cementitious materials. Compared with ordinary portland cement as cementitious material, the addition of slag powder and fly ash can replace part of ordinary portland cement, thereby reducing the amount of cement and reducing energy consumption and polluting waste gas emissions in the cement industry....
