简介：构造工程的地里的聚合物修正有历史将近90年。尽管那些修正被分类进物理修正，到某程度的机械性质，水抵抗，化学抵抗和耐久性被不同聚合物修正改进了。获得似水泥的材料的更好的性能，化学修正被测试了。在这研究，环氧基树脂与它的相应hardener在修改系统作为一个占优势的修饰词被设计了。氨基的sulfonate，添加剂，被用来改进系统可使用性。当它有特殊的功能的组，功能的silane被用来在环氧基树脂，水泥一半和氨基的sulfonate之中建立连接。红外，拉曼光谱学，DSC和NMR执行的调查表明化学连接在修改系统在所有部件之中被建立了。当曲折力量和紧张实质地被改进了，曲折测试结果介绍化学修正的好效果。
