Different Types of Concrete Admixtures For Sale. Kingsun concrete admixtures mainly include Sodium Gluconate 98% min, Sodium Naphthalene Sulfonate(SNF/PNS/FND), Polycarboxylate Superplasticizer(PCE), Sodium Lignosulfonate, Calcium Lignosulfonate. Retarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Retarders keep concrete workable during placement and delay the initial set of concrete.
