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 Reducers on Durability of Cement Mortars

Abstract:

Effects of five kinds of water reducing agents, calcium lignosulfonate(CLS), modified calcium lignosulfonate(GCL1 6A), amino sulfonic based superplasticizer(ASP), sulfonated naphthalene formaldehyde(FDN） and sulfonated melamine urea formaldehyde resin(SMUF), on the durability of cement mortars were studied including impermeability, carbonization depth and shrinkage. The research results indicate 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.

Key words: water reducer cement mortar durability
