Abstract

The use of fine aggregate as a concrete mixture in the construction of the building certainly can’t be separated from the availability of sand material in the mine. One of them is in Lembang Marinding, Mengkendek Subdistrict, North Toraja District there are materials that can be used as fine aggregate in concrete mixture. This study was conducted to determine the feasibility of sand from Lembang Marinding as a mixture of concrete. This research method is done with experimental in laboratory, that is a research which try to get physical properties of material to be used in concrete mixture with quality f’c 25 MPa. In this research make 2 concrete mixture were mixture I (using river sand) and mixture II (using mountain sand). To get the result done a series of test to concrete cube test object based on Standard National of Indonesia to get the compressive strength of concrete made with mountain sand, river sand and portland composite cement in early age of 3 and 7 days. This shows that the use of natural sand from Lembang Marinding is feasible to be used as fine aggregate in concrete mixture, the result of the average compressive strength of concrete produced mixture I at the age of 3 and 7 days were 13.36 and 16.60 MPa. Compressive strength of concrete produced mixture II at the age 3 and 7 days were 16.31 and 18.67 MPa. The results of the inspection of mountain sand in Lembang Marinding are suitable for use as fine aggregate in concrete mixtures.
