Problems solved by technology

With the rapid development of my country's economic construction, the demand for building mortar is increasing. At present, the main problems faced by the preparation of building mortar are: the production of building mortar consumes a large amount of cement and lime, and high-strength grades are often used in projects. When cement is used to prepare low-strength mortar, in order to improve the workability of construction, cement is often added in excess, resulting in waste of cement
The disorderly and large-scale mining of sand has destroyed the natural landscape and ecological environment, and also affected the safety of river embankments.

Abstract

The invention discloses a method for preparing special mortar for wall materials by using wastes. Firstly, each raw material is weighed according to parts by weight; solid construction wastes are crushed, and pentaerythritol, barium stearate, shell powder and limestone are added for heat preservation. Stir to get mixed material A; then mix slag powder, attapulgite, Portland cement, add water and stir, add sodium tripolyphosphate, ethyl naphthol to get mixed material B; mix graphite powder, magnesium sulfate heptahydrate, polytetrafluoroethylene Vinyl fiber, calcium phosphate, aluminum dihydrogen phosphate, and butyltin trioctoate are uniformly mixed to obtain mixed material C; mixed material A, mixed material B, mixed material C and simethicone are mixed and poured or sprayed into the mold. The invention has less material loss and waste, high bonding strength, low dry shrinkage, good freeze resistance durability, low thermal conductivity, good heat preservation, good workability, environmental protection and non-toxicity, and a large number of industrial waste and construction waste are used. , the development of circular economy.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing special mortar for wall materials using waste. Background technique [0002] Mortar is a kind of pre-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is mainly used for building exterior wall insulation, and has the advantages of convenient construction and good durability. Traditional construction mortars are formulated from cementitious materials (cement and lime) and natural sand. With the rapid development of my country's economic construction, the demand for building mortar is increasing. At present, the main problems faced by the preparation of building mortar are: the production of building mortar consumes a large amount of cement and lime, and high-strength grades are often used in projects. When cement is prepared with l...
