摘　　要：与天然砂相比．聚羧酸减水剂在机制砂商品泥凝土的应用中表现出了更高的敏感性对此，本文采用测试混凝上拌合物工作性能的方法．评价聚羧酸减水剂的敏感性，同时提出通过复配不同性能特点的聚羧酸产品来达到降低其在机制砂商品混凝土中应用的敏感性，提高聚羧酸综合性能的措施。The carboxylate-based superplasticizer exhibited a higher sensibility when it was applied in the manufactured sand concrete compared with natural sand. The sensibility of superplasticizer was evaluated by testing the workability of concrete mixture. The sensibility of superplasticizer could be decreased by the compound of different carboxylate-based products.
