Concrete retarder, also called concrete set retarder or set retarding admixture, is very suitable for concrete mixing. In general, Adding retarding admixtures to commercial concrete is to extend the hardening time of cement mortar, so that the fresh concrete can maintain plasticity for a long time, thereby adjusting the setting time of the fresh concrete. Besides, most concrete set retarders can be also acted as water reducers.
Setting Retarder Used In Concrete
Concrete setting retarder is often used in hot weather to counter the rapid setting caused by high temperatures. For large jobs, or in hot weather, specify concrete with retarder to allow more time for placing and finishing. As the most professional manufacturer and exporter in China, we have many years’ experience in researching and producing various types of concrete retarding admixtures, including sodium gluconate, sodium lignosulfonate.

Sodium Gluconate As Concrete Retarder
When adding fixed amount of sodium gluconate in cement, it can make the concrete strong and random, and at the same time, it also delays concrete initial and final setting time. So sodium gluconate can be used as concrete setting retarder and water reducing admixture in the construction & building industry.
Sodium Lignosulfonate As Concrete Set Retarder
Sodium lignosulfonate can be used as ideal concrete set retarder and pumping agent in construction industry. What’s more, it also acts as common water reducing admixtures. Of course, it can be compounded with snf superplasticizer.
