| Research Abstract |
Polymer cement mortar(PCM) is widely used for repair and strengthening of concrete, due to its high performance in workability, strength and durability. But, it would be uneconomical to use it in the usual environment, because the cost of PCM is about 10 times of ordinary Portland cement(OPC). In this study, as material for repair and strengthening of concrete, OPC based silica fume or fly ash modified test mortar without dry polymer powder was manufactured, and the property of test mortar was compared with PCM on the market. And the basic properties of mortar and concrete which modified super absorbent polymer(SAP) was also examined.
