| Abstract: | Through compressive strength test,flexural strength test,cement setting time test,and mixed technology test of cement slurry and cement mortar.The modifying effect of mechanism and property of polyacryamide modifying cement slurry and cement mortar are studied.Relevant test and analysis show that polyacryamide can obviously affect mixing technology and setting time of cement slurry.Moreover,polyacryamide can not only effectively enhance flexural strength and compressive strength,but also decrease the ratio of compressive strength to flexural strength. |

| Keywords: | Polyacryamide Setting time Flexural strength Compressive strength Ratio of compressive strength to flexural strength |
