Concrete Admixtures Polycarboxylate Superplasticizer is a cement dispersant used in cement concrete. It has the characteristics of being non-toxic and nonirritating and belongs to the category of green and environmentally friendly polycarboxylate high-performance water-reducing a...……

Superplasticizer is a chemical agent. Changing the chemical action ability of concrete and water can reduce the surface tension of the saturated paste of concrete and maintain the dispersion state between particles in concrete.This can reduce concrete's viscosity and friction, in...……

 Polycarboxylate superplasticizer, also known as polycarboxylate superplasticizer or superplasticizer, is a high-performance concrete admixture. It belongs to the category of anionic surfactants and has a comb-shaped molecular structure. The main chain is a polycarboxylate polyme...……

Polycarboxylic acid superplasticizer has been widely used in many construction fields. Modern concrete has high requirements for additional functional additives, so polycarboxylic acid water-reducing agent in the concrete system, it should consider the following key technologies...……

Polycarboxylate superplasticizer (PCE) is a comb-like polymer with an anionic backbone and several non-ionic vertical chains, usually consisting of polyethylene glycol.……

polycarboxylic ether is a water-reducing agent used in cement. It is a chemical substance that consists of a monomer or polymer with side chains bonded via amide groups and is used as a cement dispers……

Polycarboxylate superplasticizer can adjust and change the molecular structure according to the requirements to achieve the purpose of changing the performance, rather than using a simple compound to modify, based on this understanding, it may inspire the improvement of our appli...……

Polycarboxylate superplasticizer as the latest generation of high performance superplasticizer, different from the traditional common superplasticizer, has strong dispersibility to concrete, high water reducing rate and small slump loss of concrete, which is a major breakthrough ...……

Especially in practical engineering, due to many kinds of cement, sand and mud content in concrete raw materials and so on, when polycarboxylic superplasticizer is directly applied to concrete, there are often some problems, such as poor adaptability to cement, poor working perfo...……

In fact, the same is true of other superplasticizer, the relationship between compressive strength ratio and water reducing rate is very complicated, on the one hand, the air entraining property of different superplasticizers is different, on the other hand, the active groups and...……
