Increasing the Compressive Strength of Concrete Using PPC

Abstract Cement factories in Indonesia rarely produce OPC due to the high cost of production and less environmentally friendly, so they prefer PPC or PCC. located areas that are rich natural pozzolan will producing PPC. In general, there is an assumption increasing compressive strength concrete using slow at early age. Based on these assumptions, it necessary conduct research The specimen used was a cylinder, with 3 specimens for each variation. test carried out ages of: 3, 7, 14, 21, 28 days. From results obtained, has increased age concrete. comparable OPC. unit weight almost same all
