In tis paper, the effects of the compound use of monocalcium aluminate expansive agent (AEA) andFDN water reducer on their expansion energy and fluidness are studied on the basis of the experiments on the mortarwith AEA and FDN water reducer.

• 本文以铝酸钙膨胀剂与FDN减水剂的砂浆试验为基础，研究了铝酸钙膨胀剂与减水剂复合使用时对膨胀能、流动度的影响。
