Embodiment 1

[0021] (1) Raw material and weight:

[0022] 45 parts by weight of high-performance polycarboxylate superplasticizer with a polyester solid content of 40%; 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; parts; the air-entraining agent sodium abietate is 0.5 parts by weight.

[0023] (2) Production

[0024] Put ferric chloride into water first, dissolve it completely in water while stirring, let it cool naturally, add sodium gluconate and sucrose, then add high-performance polycarboxylate water reducer, and finally add air-entraining agent and defoamer. According to the above sequence, the raw materials are measured and put into the container, mixed and stirred until they are completely dissolved, then put into the finished product packaging tank, inspected and packaged, and the product is obtained.

Embodiment 2

[0026] (1) Raw material and weight:

[0027] 48 parts by weight of high-performance polycarboxylate superplasticizer with a polyester solid content of 40%; 18 parts by weight of ferric chloride; 10 parts by weight of sodium gluconate; 2 parts by weight of sucrose; 13 parts by weight of water; parts by weight; the air-entraining agent sodium rosinate is 2 parts by weight.

[0028] (2) Production

[0029] First put ferric chloride into water, under stirring, completely dissolve it in water, let it cool naturally, add sodium gluconate and sucrose, then add high-performance polycarboxylate water reducer, and finally add defoamer and air-entraining agents. According to the above sequence, the raw materials are measured and put into the container, mixed and stirred until they are completely dissolved, then put into the finished product packaging tank, inspected and packaged, and the product is obtained.

Embodiment 3

[0031] (1) Raw material and weight:

[0032] 47 parts by weight of high-performance polycarboxylate superplasticizer with polyether type solid content of 40%; 14 parts by weight of ferric chloride, 11 parts by weight of sodium gluconate; 6 parts by weight of sucrose; 15 parts by weight of water; parts by weight; air-entraining agent sodium rosinate is 0.5 parts by weight.

[0033] (2) Production

[0034]Put the ferric chloride into the water firstly, and dissolve it completely in the water while stirring, let it cool down naturally, add sodium gluconate and sucrose, then add high-performance polycarboxylate water reducer, and finally add air-entraining agent and defoamers. According to the above sequence, the raw materials are measured and put into the container, mixed and stirred until they are completely dissolved, then put into the finished product packaging tank, inspected and packaged, and the product is obtained.

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. ...
