Cement Industry is the third largest CO2 contributor after transportation and electricity which also donates 10% of the World Total CO2 Emission. Excessive CO2 concentration within the atmosphere could trig the global warming phenomenon which ended by unstable climate condition and increasing of the sea level. One solution to overcome this phenomenon is by decreasing the use of cement with pozzolan addition.<p> <br /> <br /> <br /> <br /> <br /> The objective of this research is to observe the possibility of using steel slag as partial cement substitution in concrete structure. Steel slag is treated as a cement partial substitution material with substitution in 5%, 10%, and 15%.<p> <br /> <br /> <br /> <br /> <br /> The testing result shows that 56 days concrete with 10% steel slag partial substitution in cement, give the highest compressive strength 37, 98 MPa compare to normal concrete 37,6 MPa. The Analysis of XRD result verify that the ratio of CSH compound present in normal concrete against 10% steel slag cement concrete is 1:1,34. Steel slag cement concrete demonstrate better workability however it exhibit slow setting time and slow strength development in the early age.
