| Summary: | Generally, the development of infrastructure, mainly in civil construction, has made the high strength concrete as its main parameter. One of the most important component in building construction is partition wall. The requirement that has to be fulfilled are good acoustic property and also high strength. Achieving good acoustic characteristic requires porous material because it can absorb sound wave rather than reflecting it. Because of the need to produce high strength-porous material for the partition wall application, research about the making of lightweight porous block concrete is needed.<p>In the making of porous concrete, gypsum waste from fertilizer industry, Schude Chemic. Inc, is used as a component. In this research, the concrete was made in three composition with three different gypsum percentage -10 %, 7.5 % and 5 %. These samples are then tested with compression testing and bending testing after autoclaving process. From the mechanical testing, we obtain optimum compressive strength from beton III (2.561 MPa) and optimum flexural strength from beton III (2.283 MPa). Porosity testing was conducted to know the concrete porosity percentage : 55.22 % (beton I), 50.30 % (beton II) dan 46.48 % (beton III). Another testing conducted was acoustic testing to identify the sound absorption coefficient of the porous concrete samples. The sound absorption coefficient of the samples is higher than the sound absorption coefficient of normal strength concrete. |
