摘要
本文论述了通过无机填料改善MMA基混凝土修补材料的收缩性能。试验结果表明,加入适当的无机填料对MMA基混凝土修补材料的收缩性能有一定的改善,但其粘度也会相应的增高,因此在保证工作性能的同时应控制无机填料的加入量。本文同时讨论了低收缩添加剂的应用机理。
This paper presents improvement on the shrinkage of the MMA based repair material for concrete by adding inorganic filler. Experiments carried out and the results show that the shrinkage of the MMA based repair material is improved by using appropriate inorganic filler, but its viscosity increases accordingly. Therefore, it should control the adding while get good workability. Reducing shrinkage mechanism of the LPA（Low Profile Additive）is discussed.
