铝酸钙膨胀剂与减水剂相容性试验研究

Experimental Study on Compatibility of Monocalcium Aluminate Expansive Agent with 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。从微观层次上，探讨了它们之间相容性的作用机理。试验结果表明，相容性的好坏与其成分有一定的关系。

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. the affecting principles of the compatibility between them are discussed in microscopic dimension. The results of the experiments indicate that the compatibility has a certain relationship with theircomponents.
