PCE polycarboxylate water-reducing agent is a new type of high-efficiency concrete water-reducing agent developed in the 1980s. It was first developed in Japan and can significantly improve the durability and fluidity of concrete. It is currently recognized as the most promising application in the world. Good water reducer with the best comprehensive performance. A polymer concrete water reducing agent produced by free radical polymerization through polymer structure design. This product has wide applicability to cement, fly ash and mineral powder, and has good water reducing rate and plastic retention performance,Features.
The water reducing mechanism of polycarboxylate superplasticizer mainly includes electrostatic repulsion and steric hindrance. When the polycarboxylate superplasticizer is added to the cement slurry, the flocculation structure of the cement slurry is destroyed, and the water wrapped in the flocculation structure is released into free water, thereby increasing the working performance of the concrete mixture.
Polycarboxylate superplasticizers are mainly available in powder and liquid forms.
The use of water reducer in concrete is as follows:
1. Low dosage and high water reduction rate, the recommended dosage is 0.2%-0.5% of the concrete cementitious material;
2. It can be used in conjunction with slow-release polycarboxylate slump-preserving mother liquor;
3. It can be used in combination with retarder, air-entraining agent and other raw materials;
4. When the user uses or replaces the concrete material for the first time, it is necessary to test the best compound formula according to other materials of the concrete;
5. This product cannot be used together with naphthalene-based water-reducing agent, and cannot share storage tanks with naphthalene-based products.
At present, there are many superplasticizer sales companies on the market, most of which are distributors, not manufacturers. If you buy a water reducer directly from the manufacturer, you will at least have the following benefits:
1. Factory prices are often more favorable than dealers.
2. A stable product supply can be obtained.
3. Different batches of products can also ensure the consistency of quality.
Hebei YIDA is a professional manufacturer of polycarboxylate superplasticizers with 16 years of industry experience. At the same time, two water reducers, mother liquor and powder, are produced. Set technology development, production, sales, international trade as one. It is a first-class industrial new material enterprise in China. The annual output of polycarboxylate superplasticizer is 60,000 tons, supplying more than 150 customers in more than 40 countries around the world.
