Retarders

Concrete set retarders are a type of additive that can be used in concrete admixtures to delay the setting time of concrete. This can be particularly useful in applications where the concrete needs to be transported over a long distance or when weather conditions are unfavorable. Set retarders work by slowing down the chemical reactions that cause concrete to set, giving workers more time to work with the material. Concrete producers can achieve optimal strength, workability, and performance in their products by carefully selecting the appropriate type and dosage of set retarder for each application.

Concrete set retarders commonly used in concrete admixtures include Sodium Gluconate, Citric Acid, Tartaric Acid, and Lignin.

In general, the strength and durability of the concrete are achieved through a longer setting time of the concrete. Therefore, it is essential to carefully balance the need for a longer setting time with the desired strength and performance of the finished product.
