Embodiment 1

[0021] (1) Raw materials and weight:

[0022] 45 parts by weight of polyester type high-performance polycarboxylic acid water reducing agent with 40% solid content; parts by weight of ferric chloride; 5 parts by weight of sodium gluconate; 3 parts by weight of sucrose; 15 parts by weight of water; 0.1 parts by weight of defoamer silicone oil Parts; the air-entraining agent sodium rosin is 0.5 parts by weight.

[0023] (Two) production

[0024] First put the ferric chloride in the water, dissolve it completely in the water under stirring, let it cool naturally, add sodium gluconate and sucrose, then add high-performance polycarboxylic acid water reducing agent, and finally add air-entraining agent and Defoamer. According to the above sequence, the raw materials are metered into the container, mixed and stirred until all dissolved, and then entered into the finished product packaging tank, inspected and packaged, and the product is obtained.

Abstract

The invention discloses a crack-resistant water-reducing and waterproof compacting agent for concrete and a production method thereof. The crack-resistant water-reducing and waterproof compacting agent for concrete is prepared from the following raw materials in parts by weight: 45-48 parts of high-performance polycarboxylate water reducer, 15-22 parts of ferric trichloride, 5-12 parts of sodium gluconate, 2-6 parts of saccharose, 10-15 parts of water, 0.1-2.0 parts of air entraining agent and 0.05-0.5 part of defoamer. The compacting agent disclosed by the invention can remarkably improve the anti-permeability, reduction, crack resistance, water-reducing rate, waterproofness and compacting effect, effectively inhibit water molecular penetration and remarkably improve the strength. The anti-permeability level of concrete reaches level 12, so that concrete particles are compactly bonded to form a wrappage to prevent permeability, and meanwhile, over 30% of shrinkage can be reduced. Particularly in severe environments, shrinkage can be reduced, and thus the compacting agent is extremely remarkable for effectively controlling the cracking.

Description

Technical field [0001] The invention relates to an anti-cracking type concrete water-reducing and waterproofing compacting agent which can be widely used in basements, swimming pools, water channels, tunnels, cable trenches of high-rise buildings and for waterproof and seepage prevention of building structures and civil structures. After using this product, no other waterproofing process is needed. The concrete is poured in one step. Background technique [0002] There are many types of waterproof products in my 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 waterproofing effects in the later stage; organic waterproofing agents have a negative effect on the strength of concrete due to their air-entraining effect. In engineering applications, most waterproofing agents increase shrinkage, and excessive shrinkage is one of the main causes of concrete cracking....
