Cement-base infiltration crystallization type water-proof precast product and preparing method thereof

Abstract

The invention relates to the field of architectural materials, aiming to provide a cement group infiltration crystalline waterproof precast member and a process for preparation. The precast member comprises infiltration crystalline material, foaming agent, cement, sand and water, the weight proportioning of each component is that infiltration crystalline material takes 2-90 portions, the foaming agent takes 0-15 portions, cement takes 0-40 portions, sand takes 0-60 portions and water takes 10-40 portions. The precast member is formed by model and produced into various shaped stereo geometry products of waterproof sheet, waterproof ring, waterproof sleeve, waterproof pipe pile and triangle water stop band and the like. The scope of application is wide, construction is convenient and cost is low, which can be used for permanent protection.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a cement-based permeable crystalline waterproof prefabricated part and a preparation method thereof. Background technique [0002] In construction engineering, most buildings are made of concrete or mortar materials. Concrete and mortar are porous substances, and the structures formed are also porous and easy to crack, and are often prone to water seepage or water leakage. Traditional building waterproofing measures generally use waterproof paint or waterproofing agent on the surface of concrete, but these measures are intrinsically waterproof, and the resulting waterproof layer has the disadvantage of poor durability, and the general life span is only 3-5 years. time, and the waterproof chemical materials used are likely to cause environmental pollution, so they are generally not applicable in some important construction projects; although there is a permeable crystalline water...

AI Technical Summary

Problems solved by technology

[0003] 1. The adhesive between the product and the pipe is prone to degumming or aging after a long time, so that leakage occurs here

[0004] 2. The product is pre-buried during concrete pouring. When the pipe hole needs to be relocated in the future, it can only be completely dismantled. The damage surface is large and the construction difficulty is also increased.

[0006] 4. Once the product leaks, it is not easy to repair

[0007] 5. Ordinary concrete, metal components, and PVC plastic parts are items of different properties, so the product life is different from concrete materials, and the durability is poor, and permanent protection cannot be achieved. After a long time, they are easily separated from each other and cause leakage.

[0008] 6. It cannot self-repair various cracks inside the concrete, cannot form an effective anti-seepage structure, and cannot achieve the ideal anti-seepage effect

[0009] 7. The comprehensive cost is high, and the iron-red oxidized water will affect the wall and pollute the environment
