Abstract

The invention discloses an impervious concrete shrinkage-reducing, water-reducing and waterproofing compacting agent and a production method thereof, wherein the compacting agent contains the following raw materials in parts by weight: 48-54 parts of a high-performance polycarboxylate superplasticizer containing 40% of solids, 13-21 parts of ferric trichloride, 5-10 parts of sodium gluconate, 3-5 parts of glucose, 10-15 parts of water, and further comprises 0.05-0.5 part of a defoaming agent and 0.1-2.0 parts of an air entraining agent. The compacting agent disclosed by the invention can significantly improve anti-permeability, shrinkage reduction, water-reducing rate, waterproofing performance and compactness; the compacting agent can effectively prevent water molecules from permeating and remarkably enhance strength; anti-permeability level is 12th, so that concrete particles are closer to bind and coverage is formed to prevent permeability, and simultaneously shrinkage is reduced for more than 30%; especially under severe environments, shrinkage is reduced; and the compacting agent is remarkable for effectively controlling a cracking effect.

Description

technical field [0001] The invention relates to an anti-seepage concrete reducing water and water-proof 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...
