Waterproof concrete compacting agent and preparation method thereof

Abstract

The invention discloses a waterproof concrete compacting agent and a preparation method thereof. The compacting agent consists of the following raw material components in percentage by weight: 10 to 13 percent of potassium hydroxide, 0.5 to 1 percent of volcanic ash, 0.5 to 1 percent of potassium oleate, 10 to 12 percent of sulfur, 0.5 to 1 percent of glycerol, 3 to 5 percent of triethanolamine, 0.5 to 1 percent of citric acid, 0.5 to 1.5 percent of ferric oxide, 0.5 to 1 percent of sodium fluosilicate, and the balance of water. Chemical crystal or colloid generated by chemical reaction of components in the compacting agent and silicon, calcium, sodium, magnesium and the like in cement can effectively prevent permeation of water molecules and effectively control cracking. The compacting agent contains extremely low harmful substances, particularly has extremely low chlorine ion content and ammonia content, reduces damage to steel bars and concrete, and is beneficial to environmental protection.

Description

Technical field: [0001] The invention relates to a building material additive, in particular to a concrete waterproof compacting agent widely used in basements, swimming pools, canals, tunnels, cable trench projects and building structures for waterproofing and anti-seepage and a preparation method thereof. Background technique: [0002] At present, there are many types of waterproofing agent products in our country, which are mainly used to improve the impermeability and crack resistance of concrete and reduce shrinkage. However, these products contain more chloride components because chloride ions are harmful to concrete. Use It is easy to corrode the steel bars later, and the waterproof effect is not good in the later stage, or because the waterproofing agent will increase shrinkage after use, causing concrete cracking, or the waterproofing agent is a powder product, and it needs to be mixed in more during use. Therefore, due to various objective factors, the current wate...

[0002] At present, there are many types of waterproofing agent products in our country, which are mainly used to improve the impermeability and crack resistance of concrete and reduce shrinkage. However, these products contain more chloride components because chloride ions are harmful to concrete. Use It is easy to corrode the steel bars later, and the waterproof effect is not good in the later stage, or because the waterproofing agent will increase shrinkage after use, causing concrete cracking, or the waterproofing agent is a powder product, and it needs to be mixed in more during use. Therefore, due to various objective factors, the waterproofing agent products in the current market often have many adverse reactions in the actual use of the project, and cannot achieve the ideal effect of using the waterproofing agent.
