摘 要: 研究了木素磺酸钙(CLS)、改性木素磺酸钙(GCL1-6A)、氨基磺酸甲醛缩合物(ASP)、萘磺酸甲醛缩合物(FDN)和磺化三聚氰胺脲醛树脂(SMUF)这5种常用减水剂对水泥砂浆抗渗性、抗碳化性和收缩性等耐久性指标的影响.结果表明:掺SMUF的水泥砂浆其长期性和耐久性最优,其次是掺GCL1-6A,FDN的水泥砂浆,而掺CLS的水泥砂浆最差. Effects of five kinds of water-reducing agents, calcium lignosulfonate(CLS), modified calcium lignosulfonate(GCL1-6A), amino-sulfonic based superplasticizer(ASP), sulfonated naphthalene formalde- hyde(FDN) and sulfonated melamine urea formaldehyde resin(SMUF), on the durability of cement mor- tars were studied including impermeability, carbonization depth and shrinkage. The research results indi- cate that durability of cement mortar mixed with SMUF is the most excellent~ durability of cement mortar mixed with GCL1-6A and FDN is next; that mixed with CLS is the weakest.
