Abstract:

The study aims to determine the characteristics and compressive strength of Portland Composite Cement with limestone as an additive. The method of analysis chemically used was X-Ray Fluorescence (XRF) and mechanically through the physical test compressive strength. The results of the research indicated that the Portland Composite Cement containing components CaO and SO3 is high (70.96% and 4.81%). Besides, Al2O3 was not found in the cement. Whereas the results of the compressive strength test descending for 3 days (33,86%), 7 days (45,60 %), 28 days (21,10%) from SNI minimum standard.
