Using Polycarboxylate superplasticizer dosage is relatively low, water reduction rate is high, and the nature of early strength and high strength. Using polycarboxylic acid superplasticizer in the range of low dosage, the strength growth needs to increase significantly with the dosage, if the optimal dosage is exceeded, the strength will not increase again.
When adding polycarboxylic acid superplastifier, the situation of collapse is relatively low, which remains unchanged at low positive temperature, and the degree of expansion is increased. If the temperature is greater than 20 degrees, the slump is slightly lost. With a slight loss of slump in the condition of high slump, there will be no segregation or bleeding, water reducing agent is mainly suitable for high grade concrete, and easy to mix.
The durability of polycarboxylate superplasticizer is better, and its filling and stability are better than that of ordinary superplasticizer. When it is mixed with different kinds of cement, the compatibility of other kinds of superplasticizer and cementitious materials can be solved. After using polycarboxylic acid superplasticizer, the product will have better stability, and there will be no precipitation at low temperature. It is a very green product, which can reduce the pollution to the environment.
