How is concrete water-reducing agent not set to return a responsibility?

Concrete water-reducing agent is an indispensable new material in the construction of building engineering, 

which plays a very important role in improving the performance of concrete and enhancing the construction 

quality of building engineering. However, in the process of the use of concrete water reducing agent will also 

appear this or that problem, such as concrete water reducing agent does not condense, so what is this? 

Concrete water reducing agent does not condense how to solve?

The so-called concrete water reducing agent is not set after the use of water reducing agent, concrete for a long 

time or even a day and night is not set, and the surface of the pulp is yellowish brown, 

the main reasons for this phenomenon are as follows:

1. The dosage of water reducing agent is too large, it is likely to exceed the recommended dosage of 3-4 times

2. Excessive use of retarding agent.

The solution of concrete water reducing agent is not coagulative:

1, do not exceed the recommended dosage 2-3 times, the intensity of the year slightly decreased, 

but the long-term intensity reduction is less;

2, after the final setting, improve the curing temperature appropriately, strengthen watering curing;

3. Remove the formed part and re-pour.
