BTC功能型外加剂做为一种复合型混凝土添加剂，能与聚羧酸减水剂产生“配伍效应”，其在混凝土体系中分散效果明显好于单掺混凝土减水剂。针对机制砂混凝土体系，BTC功能型外加剂的掺入能有效提高混凝土流动性及和易性，同时在不降低混凝土强度的前提下有效降低单位立方米混凝土胶凝材料用量。通过本技术手段可有效利用机制砂作为混凝土细骨料，并降低混凝土单位立方米成本。

BTC functional additive has a compatibility effect on polycarboxylate superplasticizer as a composite concrete additive. Its dispersion effect is much better than the water reducing agent only mixed in the concrete system. In view of the mechanism of sand con-crete system,BTC functional additive can improve the liquidity and workability of the concrete who can also reduce the unilateral con-crete gelled material consumption without reducing the strength of concrete. So the mechanism of this technology can use sand as fine aggregate concrete effectively,and reduce the cost of concrete unilaterally.
