The choice of concrete polycarboxylate superplasticizer should depend on the construction performance of concrete and the type of water-reducing agent needed.
Naphthalene series superplasticizer is sufficient for ordinary concrete and early strength.
High strength water reducer can be high efficiency water reducer and high performance water reducer.
Analysis of the advantages of polycarboxylate superplasticizer Various superplasticizers have their own characteristics and cannot be exchanged with each other.
If the use of high efficiency superplasticizer as high-performance superplasticizer, the use of standard superplasticizer as early strength superplasticizer, it is inappropriate and uneconomical.
According to the water reducing agent manufacturer's technical level, convenience and economy, choose water reducing agent brand.
Most water reducers are compound water reducers, both liquid and powder.
Mixing stations are well equipped, lack of professionals and are uncertain about dosage, which seems to save money.
In fact, the harm and economic loss caused by improper use is even greater.
According to the compatibility of cement and water reducer, determine the brand of water reducer.
The incompatibility between concrete water reducer and cement will affect the quality of concrete and normal production.
Therefore, water reducer should be tested before use, and should not be used before there is no problem.
Concrete shall be suitable and the material shall be evenly and accurately poured during production and construction.
The dosage and composition of water reducing agent should be adjusted in time according to the situation.
polycarboxylate superplasticizer has become an indispensable part of modern concrete, which makes concrete have good working performance, volume stability and high durability.
Polycarboxylic acid water reducer is a leap and a challenge.
Therefore, the user of water reducing agent should choose the most economical and effective water reducing agent according to the performance requirements of concrete.
