In hot summer, it is a common problem that concrete sets too fast during construction. However, it is easy to prolong the setting time of concrete and make the construction more smooth by using suitable retarder. Below, let's learn more about the function and usage of the retarder.

Function of reducer

Retarder is a chemical substance that can delay the setting speed of concrete. It can react with cement in concrete to form gel substance, thus prolonging the setting time of concrete.

How to use the retarder

The use of retarder is very simple. In the process of concrete mixing, an appropriate amount of retarder is added to the concrete, and then the concrete is mixed. It should be noted that the dosage of retarder should be adjusted according to the specific situation to achieve the best effect.

Advantages of retarder

There are many advantages to using retarder. First of all, it can prolong the setting time of concrete and make the construction more smooth. Secondly, it can improve the fluidity of concrete and reduce the shrinkage and cracks of concrete. In addition, it can improve the strength and durability of concrete.

Precautions for retarder

When using the retarder, you should pay attention to the following points. First of all, the dosage of retarder should be appropriate, too much or too little will affect the performance of concrete. Secondly, the type of retarder should be selected according to the specific situation. Finally, the quality of retarder is also very important, so we should choose products with reliable quality.
