Application

Sodium gluconate is used to added to concrete to delay the setting for cement and concrete,especially in summer,sodium gluconate added to concrete and cement can abviously reduce slump loss and extend the workability of the fresh concrete,and the adding doesn’t influence the final concrete strength.

The adding rate is about 0.03%-0.07%,when applied to concrete,recommend to do a test to determine the proper adding rate.
