Its important characteristics and application effects are as follows: Sodium gluconate has a corrosion and scale inhibition effect, and is widely used as a water quality stabilizer. Sodium gluconate is used as a water reducer and retarder in concrete engineering. Sodium gluconate has strong scale inhibition ability and strong chelating ability towards calcium, magnesium, and iron salts; Sodium gluconate, as a corrosion and scale inhibitor for circulating cooling water, is also a major advantage in achieving environmental protection. Sodium gluconate has a wide range of applications, including pumped concrete, high flow concrete, large volume concrete, and high-performance concrete.
