랜덤입사방법에 의한 포러스 콘크리트의 흡음특성에 관한 실험적 연구
The Study on Sound Absorbing Characteristics of Porous Concrete according to Reverberation Room Methods
초록
This research estimated the physical. mechanical characteristic and the character of sound absorption according to target void ratio of porous concrete and the mixing ratio of recycled aggregate for the valid utilization of recycled aggregate using waste concrete and sound reduction out of a road, a railway, a residential street, and a downtown area. As a result of the test, compressive strength tended to be a radical strength fall when target void ratio was
