A kind of preparation method of high-efficiency plugging and waterproof mortar

Abstract

The invention provides a preparation method of high-efficiency plugging and waterproof mortar, which is characterized in that the raw materials are weighed according to the following mass percentages: 25-30% ordinary Portland cement, 5% solar silicon chip cutting waste, 3% banana fiber , 5% waterproof material, 30-35% quartz sand, 26-32% liquid material, and then stir evenly; the liquid material is uniformly mixed by 40 parts by weight of acrylic emulsion, 55 parts by weight of water, and 2 parts by weight of water reducer ; Hydrophobic flakes made of alloy compounds are used as waterproof materials to improve waterproof performance, and solar silicon wafer cutting waste is added to improve the compactness and strength of the mortar, and improve the anti-seepage and anti-leakage performance.

Description

technical field [0001] The invention relates to a preparation method of high-efficiency plugging and waterproof mortar, which belongs to the technical field of building materials. Background technique [0002] As the society has higher and higher requirements for the quality of construction projects, the building structure itself is developing in a complex direction such as large volume and large area, and because the underground environment where the buildings are located is getting worse and worse, large areas of saline-alkali land, coastal and offshore areas The development of the development, the groundwater and soil rich in acidic medium are highly corrosive to buildings, and the durability and safety of concrete structures have become the most important problems to be solved in the construction industry. To improve the quality of concrete structures, waterproofing materials are widely used. However, the quality of various rigid waterproof materials on the market is un...

AI Technical Summary

Problems solved by technology

These traditional reinforcement methods have disadvantages such as poor corrosion resistance, heavy component weight, great impact on the original structure, and difficult construction. Therefore, new materials and new processes are needed for reinforcement projects

[0004] Once there is leakage in the building structure, it will not only affect the normal use, but also shorten the service life of the building, so waterproof and plugging treatment is an effective solution

For example, the Chinese patent application number is 03111858.5, and the patent named "quick leak plugging agent" provides a fast leak plugging agent with high strength and short setting time. The leak plugging agent improves its early strength by changing the composition of the cement base material. and shorten the setting time, but did not improve the impermeability strength, and the use of chloride salt as a coagulant is not conducive to the protection of steel bars in concrete structures

The Chinese patent application No. 200410099364.6 provides a plugging and waterproofing material. The plugging and waterproofing material is a cementitious material system compounded with Portland cement and high alumina cement clinker, and is solved by adding bentonite. The problem of water seepage in cracks, because the whole system is affected by the fluctuation of the mineral composition of Portland cement and high alumina cement clinker, it is easy to lead to uncontrollable setting and hardening time, and the patent does not consider the problem of negative growth in the late strength of the compound cementitious material system

However, the use of high-volume bentonite may easily lead to a decrease in the strength of the waterproof material, thereby reducing the compactness of the waterproof material and ultimately affecting the impermeability.
