REDUCING THE USE OF CEMENT WITH MARBLE WASTE FOR SEASIDE CONCRETE CONSTRUCTION THROUGH THE GRAPHITE CARBON PARTICLES SYSTEM

Abstract

This research aims to save the environment by reducing the dredging of natural resources and air pollution in cement factories which produce a lot of CO2 emissions through the use of marble industrial waste. By reducing the amount of cement by 25% and replacing it with Carbon Graphite Particle Marble Powder for concrete construction work with a design quality of K-250 or fc' 20.75 MPa by using it in buildings by the sea under the influence of sea air, the concrete quality is obtained higher than the quality design concrete is 22.76 MPa > 20.75 MPa. The compressive strength testing process was carried out based on ASTM C 39/C 39M - 05. Meanwhile, for workability, based on the slump test results, a 12 cm slump value was obtained with the testing process referring to SNI 1972: 2008 and ASTM C143/C143M-12. Refining marble waste using a grinder with a capacity of 5.5 HP equipped with a 200-micron filter. The combustion process uses a high-pressure combustion engine with combustion capabilities of up to 20000 C. Carbon particles are obtained at temperatures between 8500 C and 9000 C for 120 minutes. Temperature measurement using an Infrared Thermometer with a capacity of up to 15000 C.
