When the same polycarboxylic acid sloughing agent is used but different cement is used, it is possible that this polycarboxylic acid sloughing agent has good compatibility with one kind of cement but poor compatibility with another cement, and when u Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer. Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the Common superplasticizers include lignosulfonates and their derivatives, advanced polyols and polyol complexes, hydroxy carboxylic acids and their salts, polyvinyl ethers and their derivatives, etc. Polycarboxylate superplasticizer is often used in concrete, which can reduce the water consumption of concrete while maintaining the same fluidity, thus improving the strength and durability of concrete. Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is Natural river sand has been exhausted after decades of large-scale mining, concrete production enterprises began to use machine-made sand as fine aggregate on a large scale. In order to improve the early strength of concrete, some manufacturers will add triethanolamine, calcium chloride and industrial salt to the superplasticizer, especially in winter or prefabricated component factories and cement products factories tha If the compatibility of polycarboxylate superplasticizer and cement is not good, the concrete mixture is prone to some problems, such as segregation, bleeding, greater slump loss, shorter setting time and so on, so that the concrete mixture can not b The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.
