Abstract

The cement industry has remarked as an intensive consumer of energy. The amount of energy consumed in the cement manufacturing has a correlation to the increasing of CO2 emission. It is reported that the cement Industry has contributed to 5–7% of the total CO2 emission in the world. Thus, there is a need to make an innovation in order to overcome the environmental problem. One of effort can be made is by using chemical grinding aids (CGA) as an additive material in the cement production process. This study aimed to determine the optimal clinker factor of the cement production by the addition of chemical grinding aids (CGA). The experiments are conducted in PT Semen Padang consisting of four variable of the clinker factor without CGA and with CGA addition 300 ppm. The clinker factor varies from 78.3% to 72.9%. The results show that the optimal clinker factor is at 74.5% with the CGA addition 300 ppm. It can improve the cement fineness to 3848cm2/gr and decrease the sieving R45μ to 10%. In addition, the strength of the cement produced is higher than the standard. The findings show the chemical grinding aids (CGA) addition in the cement production process can reduce the clinker factor as well as reducing the CO2 emissions. It can aid the cement industry to achieve the higher performance in green manufacturing and so as to increase the competitiveness.
