Problems solved by technology

The amount of polymer (solid content) generally accounts for 5 to 15% of the weight of cement, and the cost of each mortar or concrete will increase by hundreds of yuan or even thousands of yuan; at the same time, due to the insufficient hydrophilicity of the polymer, bleeding is easy to occur , it is often necessary to add a water-retaining agent, so that the cost of the mortar is higher, making it difficult for the polymer mortar to be accepted by the general construction market
(2) Fiber-reinforced mortar, fiber is used in cement mortar and concrete. Due to its good chemical stability, it can effectively control the cracks caused by shrinkage of mortar and concrete, improve their crack resistance and impermeability, and improve frost resistance. ability; at the same time, it has the advantages of simple mixing process, low price, and convenient construction, but due to its high price, it is currently difficult to promote in the market

Abstract

The present invention relates to an impermeable moisture-proof pre-stirring mortar and a production method thereof, wherein the raw materials comprise, by weight, 40-55 parts of an aggregate, 40-50 parts of superfine 52.5 portland cement, 3-5 parts of high activity permeable crystallization master batch, 5-15 parts of nanometer calcium carbonate, 0.2-0.8 part of a water reducing agent, 0.5-2 parts of a coagulation promoting enhancer, 1-3 parts of redispersible latex powder, 0.1-0.4 part of cellulose ether, 0.02-0.05 part of an anti-foaming agent, 0.2-0.5 part of polypropylene fibers, and 0.1-0.3 part of zinc stearate. According to the present invention, the slurry obtained by stirring the impermeable moisture-proof pre-stirring mortar according to a proper water to material ratio has advantages of cracking resistance, penetrating crystallization, moisture resistance, impermeability and excellent hydrophobicity, and can be used in the fields of building basements, pools, toilets, inner and outer walls, and the like.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to an impermeable and moisture-proof ready-mixed mortar suitable for the fields of building basements, pools, toilets, interior and exterior walls, and a production method thereof. Background technique [0002] Mortar is one of the most widely used and widely used building materials in construction projects. It is widely used in building masonry and plastering projects. In my country's current construction projects, more than 60% of buildings are still using bricks, blocks and other wall materials, and the construction mortar used in masonry and plastering construction is still mainly cement mortar or mixed mortar. [0003] Mortar cracks and water seepage are very common phenomena in construction engineering. The occurrence and expansion of cracks will cause leakage of building walls and shedding of stucco layers, which will lead to carbonation and erosion of inner co...
