Concrete admixtures, it refers to the material added to improve concrete performance before or during the mixing of mixed concrete. The amount of concrete admixture is generally not more than 5% of the cement quality.
Superplastic also know as high rang water reducer,obviously see it high efficiency water reduce,meanwhile improve the cement fluidity,the most important is environmental friendly.
In the early 19th century, dispersive admixtures were used. However, in the 1960s, sulphonated melamine formaldehydes and analogous naphthalene derivatives were introduced. Nowadays, new admixtures based on polycarboxylate ethers are being developed. Polycarboxylate ethers possess structural characteristics that provide more fluid concrete, which is more resistant to segregation and exudation as compared to that prepared with the previously known superplasticizers. Polycarboxylate ethers have been commonly utilized to enhance the flow ability of cementitious materials. Moreover, polycarboxylate ether is one of the most effective types of plasticizers, water reducer, and disperser which promotes excellent flow ability, high strength, workability, and pump ability, and efficient dispersion for gypsum, cement, and ceramic materials.
Polycarboxylate superplasticizer has excellent performance such as high water-reducing rate, small slump loss and no pollution. It is an important component of high-strength and high-flow concrete and high-volume fly ash concrete.
Polycarboxylic acid-based high-performance water-reducing agent (liquid) is the third-generation high-performance water-reducing agent developed after the general water-reducing agent represented by wood calcium and the superplasticizer represented by naphthalene series. The most advanced water-reducing agent with the highest cutting edge, the highest technological content, the best application prospect, and the best overall performance. PCE polycarboxylic high-performance water-reducing agent represents the most technologically advanced superplasticizer in the world today. Comparing with the performance of similar products at home and abroad, PCE polycarboxylate-based high performance water-reducer has reached the international advanced level in terms of technical performance and cost performance.
