Masonry mortar produced by construction solid waste

Abstract

The invention discloses a masonry mortar produced by construction solid waste. The masonry mortar comprises the following raw materials in parts by weight: 150-200 parts of cement, 900-1,200 parts of construction solid waste, 20-30 parts of glazed hollow beads, 30-40 parts of limestone, 10-20 parts of shell powder, 2-3 parts of magnesium sulfate heptahydrate, 5-10 parts of redispersible emulsion powder, 2-3 parts of polytetrafluoroethylene fibers, 0.8-1 part of Butyl tin tris-2-ethylexanoate, 2-3 parts of calcium phosphate, 4-6 parts of graphite powder, 1-2 parts of nano carbon powder, 1-2 parts of aluminium dihydric phosphate, 0.8-1 part of triethavolamine oleate soap and 2-4 parts of aluminum nitride powder. The masonry mortar provided by the invention is low in cost, can be used only by adding water and uniformly stirring according to the required amount during construction operation, is low in material consumption and waste, and has the advantages of high adhesion strength, low dry shrinkage rate, excellent anti-freezing durability, low thermal conductivity, good heat preservation performance, favorable workability, environmental friendliness and innocuity.

Description

technical field [0001] The invention mainly relates to a masonry mortar, in particular to a masonry mortar produced by using construction solid waste. Background technique [0002] The use of construction solid waste such as waste concrete blocks, standard bricks and (hollow) aerated concrete blocks has become a commonly used material for energy saving requirements. However, due to its large monomer size and relatively low strength, it is difficult to Due to improper operation, it is easy to produce blocks with missing edges and corners, and these blocks will not be used in the main project. The previous treatment was often transported back to the factory for refilling or thrown away as construction waste. These two methods will cause a large waste of resources. Therefore, according to the actual situation of the project, the project research group divides the application into the following types, and buys crushing equipment to crush and recycle construction waste: [0003...
