| Abstract: | This article has compared the data from the autogenous shrinkage experiments on cement mortar the equal fineness and mixing amount of quadruplet cement clinker,and different mixture rate of class-HI fly ash and ultra fine fly ash. The experiments result indicated that class-Ⅲ fly ash is more advantageous than the ultra fine ash in reducing the autogenous shrinkage of cement mortar. |
