Different Types of Concrete Admixtures For Sale

    • Sodium Gluconate: Adding fixed amount of sodium gluconate in cement can make the concrete strong and random.
    • Water Reducing Admixtures: Water-reducing admixtures are mainly used to reduce the water-cementitious content of concrete, thus increasing strength. In some cases, they can be used to increase the workability or slump of the concrete providing for easier placement.
    • High Range Superplasticizers: Can greatly reduce the amount of water used for mixing under the condition that the concrete slump is basically the same. By the way, Kingsun concrete superplasticizer for sale mainly includes SNF and PCE.
    • Concrete Plasticizers: can be used for improving workability of concrete. The strength of concrete is a major function of water cement ratio. Concrete plasticizers are added in concrete in amount of 0.1 % to 0.4 % by weight of cement.
    • Concrete Retarders: They are used to delay the initial setting time of the concrete upto an hour. Retarders for concrete are generally used in the hot weather condition to counter the rapid hardening due to high temperature, thus allowing the time for mixing, transporting and placing. Of coourse, concrete retarder also acts as water reducing agent.
