Nano concrete additive and preparation method thereof
Calcium neutralized polycrystalline silicon solid waste is used as a raw material, and the nano calcium silicate concrete additive is obtained after deslagging by a sedimentation method, desalting by a washing method, drying and crushing. The concrete additive is an ideal additive for nanometer-micrometer micro-grading of concrete. The microcosmic compactness of the concrete can be effectively improved, and a concrete product with excellent mechanics and permeation resistance is obtained. And the nano filler can also be plastic, rubber and the like.
以钙中和多晶硅固废为原料，沉降法脱渣、洗涤法脱盐，干燥、破碎后得到纳米硅酸钙混凝土添加剂。该混凝土添加剂是混凝土纳米～微米微观级配之理想添加。可有效提高混凝土微观密实度，获得优异力学及抗渗透之混凝土制品。亦可为塑料、橡胶等纳米填料。
