Sodium Gluconate, used as a cement admixture, adding a certain amount of Sodium Gluconate will increase the plasticity and strength of the concrete, as retardation, namely to postpone the concrete setting time of the initial and final, such as adding 0.15% Sodium Gluconate It may bring more than 10 times of curing time for fresh concrete, which can maintain the plasticity of concrete, according to the need, a few hours to a few days and without affecting its fastness.

Main performance:


Sodium Gluconate can be used as water reducing agent and retarder in the building industry. Sodium gluconate is also an efficient set retarder and a good plasticiser & water reducer for concrete, cement, mortar and gypsum. Excellent chelating agent, highly efficient set retarder, efficient plasticiser / water reducer, Bitterness inhibitor, Non toxic, easily biodegradable (98% after 2 days)
