USE OF MERAUKE FINE AGGREGATE AND DIGOEL BOVEN COARSE AGGREGATE ON CONCRETE COMPRESSIVE STRENGTH

The increasing development needs in the construction sector indirectly require the availability of substantial material in the area. The use of concrete materials in Merauke Regency is currently increasing, so that the constituent materials used are expected to use from the surrounding environment to be used in concrete-making mixtures. The purpose of this study was to conduct an alternative study, namely the combination of local aggregate in Merauke Regency, with fine aggregates and coarse aggregate from Boven Digoel Regency. The method used in this study is experimental using SNI 03-2834-2000 (Procedures for Making Mixed Plans). Fine aggregates originating from Jagebob Raya Village, Merauke Regency and coarse aggregates from Boven Digoel Regency. From the results of laboratory tests conducted, the concrete compressive strength obtained at the age of 3 days, obtained a value of f'c = 14.27 MPa and for age 7 days the concrete compressive strength value is f'c = 15.85 MPa
