Abstract
In this paper,the influence of fly ash and fiber on the workability and mechanical properties of polymer modified mortar was studied.The results show that the consistency of polymer modified mortar increases,the water retention rate decreases,the compressive strength and the ratio of compressive-flexural strength decreases with the increase of fly ash content.the consistency of polymer modified mortar decreases,the water retention rate increases,the compressive strength and the ratio of compressive-flexural strength decreases with the increase of fiber content.When the content of fly ash is 15％and the content of fiber is 0.3％,the workability of polymer modified mortar is improved,the compressive strength at 7 d and 28 d decreases,and the ratio of compression-flexural strength decreases obviously.Although the fly ash and fiber can not improve the compressive strength,they have a good composite effect on the flexural strength of mortar.关键词
