How to prevent the deterioration of polycarboxylic acid superplasticizer in summer

Into the hot summer, affected by the high heat environment, polycarboxylic acid superplasticizer

is easy to deteriorate. Deterioration of polycarboxylic acid superplasticizer performance will

inevitably decline, will directly affect the use of concrete value, so it is very important to do 

a good job in summer polycarboxylic acid superplasticizer deterioration work.

How to prevent polycarboxylic acid superplasticizer deterioration in summer?

1. Appropriate amount of preservatives should be added in the mixing process.

In other words, in the production process of polycarboxylic acid superplasticizer, 

a part of preservatives can be mixed, so as to prevent the deterioration of polycarboxylic 

acid superplasticizer, but the cost increase is about 10-25 yuan.

2, choose sodium gluconate retarder.

At present, there are many suppliers of sodium gluconate retarder in the market. 

Manufacturers with strict production control system can control the residual 

amount of glucose and Aspergillus Niger in the production process to reduce 

the risk of deterioration of polycarboxylic acid water reducer.

3, reasonable storage of polycarboxylic acid water reducer.

Try to store polycarboxylic acid superplasticizer in a cool, ventilated, dry place, 

so as to prevent polycarboxylic acid superplasticizer black deterioration.

Of course, there are many reasons for the deterioration of polycarboxylic acid superplasticizer in summer. 

In order to prevent the deterioration of polycarboxylic acid from affecting the normal use of concrete,

the above three methods should be reasonably mastered.
