| Abstract: | For improving the mortar property,the mortars mixed with polymer were studied,included the fresh mortar workability and the harden mortar mechanical property.The results indicated that the polymer could low the ratio of water to binder,alter the air content,improve flexural to compressive and bond strength.The optimum mortar could be used for strengthening and mending concrete structure. |
