Analisa Karakteristik Beton Non Struktural Menggunakan Cangkang Sawit Sebagai Agregat Kasar

Abstract

On-structural concrete consists of sand, coarse aggregate (palm shell / crushed stone), portland cement adhesive materials and water. Palm shells are treated as coarse aggregate in the concrete mix non-structural as palm shells loud enough to rupture the field are pretty much expected to be able to replace the coarse aggregate properties. Productivity palm shells are quite large in Riau Province with the extent of oil palm plantations.Primary data collection that consists of data analysis grain palm shells, sand grains of the data analysis, the data characteristics and non-structural concrete compressive strength. The materials used are cement Padang kind of PCC, sand from the lake bingkuang Kampar and palm shells of PTPN V Raja Beach Kampar. Samples of concrete for compressive strength test 48 unit cube size of 15 cm x 15 cm x 15 cm.Grain fineness modulus value of palm shell was 6.80, the apparent specific gravity of 1.14 g / cm3, density SSD 1.12 gr / cm3 and a bulk density of 0.96 g / cm3 and palm shell solid volume weight 0.588 kg / liter. Conditions palm shells are used fairly clean with mud levels only 0.15%. Characteristics of concrete mix fas shows that at 0.40, the optimum value of compressive strength is 4,721 MPa which occurred in the percentage of palm shells 60, 25%, on fas 0.45, the highest optimum compressive strength value was 5.213 MPa which occurred in the percentage of palm shell 51 , 83% at 0.50 fas, optimum compressive strength value was 4.507 MPa which occurred in the percentage of 50% palm shells, the fas 0.55, optimum compressive strength value was 4.799 MPa which occurred in the percentage of 54.167% palm shells and there ± 80 % test sample value of its slump entering the boundaries slump concrete mix
