摘　　要：根据分子结构设计思想 ,通过改变原材料克分子比和加料方法、溶液浓度和酸碱度等工艺参数 ,进行合成氨基磺酸系减水剂的工艺试验 ,结果表明 ,氨基磺酸系减水剂的综合性能可以达到最佳 ,即同时具有高效减水、增强作用和控制混凝土坍落度损失的功能 。Based on the molecule structure design theory,the experiment of synthesing Amino Sulfonic Acid based Water Reducer is done by modifying technology parameters,such as the molecule ratio,aqua concentration and acidic alkalinity etc..the results indicate that,the synthetic properties,namely,functions like the highly water ruducing and strength enhancing and contolling the slump loss of concrete,can all attain to thier optimum,so the Amino Sulfonic Acid based Water Reducer is an ideal high performance water reducer.
