To augment using of recycled fine aggregate, it grasp properties of required fluidity, compressive strength and tensile strength of concrete that use recycled aggregate according to replacement ratio of recycled fine aggregate and. fine/total aggregate percentage(S/A). Result of this experiment is as following. 1)In same relative water absorption, slump was high in S/A 42%, and both 47% and 52% were similar. 2)Effect that S/A gets to workability of recycled aggregate concrete appeared notedly in above S/A 47%, and was similar with normal concrete in S/A 42%. 3)According as S/A increases, decrease width of change with time, and were obvious as replacement ratio of recycled aggregate increases. 4)As relative water absorption increases, compressive strength increased. 5)Although water absorption of specimen was not influenced by kind of recycled aggregate and the replacement ratio, as fine aggregate percentage is low, absorption of specimen is high. |
