Embodiment 1

[0020] (1) Raw materials and weight:

[0021] 53 kg of polyether type high-performance polycarboxylic acid water reducing agent with 40% solid content; 15 kg of ferric chloride, 5 kg of sodium gluconate; 3 kg of sucrose; 15 kg of water.

[0022] (Two) production

[0023] Put the ferric chloride into the water first, dissolve it completely in the water under stirring, let it cool naturally, add sodium gluconate and sucrose, and then add the high-performance polycarboxylic acid water reducing agent. 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, and the packaging is inspected to obtain the product.

Embodiment 2

[0026] 52 kg of polyester type high-performance polycarboxylic acid water reducing agent with 40% solid content; 16 kg of ferric chloride; 5 kg of sodium gluconate; 3 kg of sucrose; 15 kg of water.

[0027] (Two) production

[0028] Put the ferric chloride into the water first, dissolve it completely in the water under stirring, let it cool naturally, add sodium gluconate and sucrose, and then add the high-performance polycarboxylic acid water reducing agent. 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, and the packaging is inspected to obtain the product.

Embodiment 3

[0030] (1) Raw materials and weight:

[0031] 54 kg of polyether type high-performance polycarboxylic acid water reducing agent with 40% solid content; 19 kg of ferric chloride, 9 kg of sodium gluconate; 5 kg of sucrose; 15 kg of water.

[0032] (Two) production

[0033] Put the ferric chloride into the water first, dissolve it completely in the water under stirring, let it cool naturally, add sodium gluconate and sucrose, and then add the high-performance polycarboxylic acid water reducing agent. 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, and the packaging is inspected to obtain the product.

Abstract

The invention discloses a concrete contraction-reducing, anti-cracking, water reducing and proofing compacting agent and a preparation method thereof. The concrete contraction-reducing, anti-cracking, water reducing and proofing compacting agent is prepared from the raw materials in parts by weight: 52-55 parts of high-performance polycarboxylic type water reducer with the solid content of 40 percent, 15-20 parts of ferric chloride, 5-10 parts of sodium gluconate, 2-7 parts of sucrose and 10-15 parts of water. With the adoption of the concrete contraction-reducing, anti-cracking, water reducing and proofing compacting agent, the impermeability, the contraction reduction, the crack resistance, the water reducing ratio and the compacting effect can be greatly improved, permeation of water molecules is effectively prevented, the strength is greatly strengthened; and as the anti-permeability level reaches level 12, concrete particles can be adhered together very tightly and also form a coating, so that impermeability is reached, contraction can be reduced by above 30 percent, and especially in the severe environment, the contraction can be reduced, and the effect of effectively controlling cracking is outstanding.

Description

Technical field [0001] The invention relates to a concrete shrink-reducing, crack-reducing, water-reducing and waterproofing compaction agent which can be widely used in basements, swimming pools, water channels, tunnels, cable trenches of high-rise buildings and for waterproofing 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 an adverse 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 co...
