Crack-resistant concrete water-reducing and waterproof compacting agent and production method thereof

Abstract

The invention discloses an anti-crack concrete water-reducing and waterproof compacting agent and a production method thereof, which comprises the following raw materials in parts by weight, wherein, 45-48 parts of high-performance polycarboxylate water-reducer; 15-48 parts of ferric chloride 22 parts; 5-12 parts of sodium gluconate; 2-6 parts of sucrose; 10-15 parts of water; 0.1-2.0 air-entraining agent; Cracking, high water-reducing rate, waterproof, compact effect, effectively prevent water molecules from penetrating, significantly improve strength, impermeability level reaches 12, can make concrete particles bond more tightly and form packages to achieve impermeability at the same time It can reduce shrinkage by more than 30%, especially in harsh environments, and can reduce shrinkage, which is extremely effective in controlling cracking.

Description

technical field

[0001] The invention relates to an anti-crack concrete water-reducing and waterproof compacting agent which can be widely used in basements, swimming pools, canals, tunnels, cable trench projects, building structures and civil structures of high-rise buildings for waterproofing and anti-seepage. After using this product, there is no need to do other waterproofing procedures. Concrete is cast in one shot. Background technique

[0002] At present, there are many types of waterproof products in our country. There are inorganic salt water repellents and organic water repellents. Inorganic salt waterproofing agents may not only corrode steel bars, but also have poor waterproof effect in the later stage; organic waterproofing agents have adverse effects on concrete strength due to their air-entraining effect. In engineering applications, most waterproofing agents will increase shrinkage, and excessive shrinkage is one of the main reasons for concrete cracking. ...
