Pengolahan Pasir Silika Lokal Skala Pilot Plant sebagai Pengganti Pasir Standar Ottawa untuk Pengujian Kuat Tekan Mortar Semen
Abstract
This research is the development of laboratory scale research on the use of local silica sand in Indonesia as a substitute for Ottawa standard sand for cement mortar testing. From several local silica sands in Indonesia, Sidrap sand originating from South Sulawesi was selected for further development on a pilot scale. Silica sand processing included the process of washing, drying, sieving or gradation in accordance with ASTM C778. The characterization of the processed silica sand included SiO2 content, sludge content, petrological analysis, roundness, and cement mortar compressive strength test at 3, 7 and 28 days and the results were compared to those of standard Ottawa sand.
