Plasticizers are widely used polymer additives in industrial production to improve the performance of polymer materials, reduce production costs, and increase production efficiency. High-efficiency water-reducing agent refers to an additive that can reduce the amount of water used for mixing and improve the strength of concrete under the conditions of unchanged concrete workability and cement dosage; or save the amount of cement under the conditions of unchanged workability and strength. Add plasticizers to concrete additives. Generally, the higher the water content of concrete, the better its fluidity and processability. But when the concrete has enough water, the strength and water content of the concrete after setting are inversely proportional. Therefore, if the concrete has high strength, the amount of water in the concrete cannot be excessive, and the workability at this time will be deteriorated, so plasticizers are added. Difference between plasticizer and superplasticizer The characteristics of polycarboxylic acid high performance water reducer are low dosage, high water reduction and high reinforcement. Therefore, it is more suitable for the preparation of medium and high-strength concrete and high-flow concrete with higher water reduction requirements. In addition, the product has better slump retention performance, so it is better applied in high-strength liquid concrete and pumped concrete. Low-strength grade concrete is difficult to exert its advantages due to the use of less cementitious materials. Because the water consumption of low-strength concrete is too large, a small amount of polycarboxylic acid high-performance water-reducing agent can not inhibit the bleeding of concrete, and the quality of concrete is difficult to guarantee. http://www.dongkepce.com
