This research is one of the efforts to reduce the impact of CO2 emissions by cement factory, by making blended cement by mixing Sidoarjo Mud (Lusi) with portland cement. Lusi contains the components of SiO2, Fe2O3, Al2O3, CaO and other components very potential to be utilized as an additive to the cement for the manufacture of concrete and building. The Lusi utilization begins by drying the material in the Oven at 100°C for 1-2 hours and refining to 120 mesh. Furthermore, the calcination process in the furnace at a temperature of 700 derajat C, 800 derajat C, 900 derajat C, for 1 hour. Calcined ligands are mixed with 10-60% cement (w/w) to cement blended (cement podzoland). The final cement mixture analyzed the chemical composition and the physical properties test comprising the compressive strength test and the setting time, the cement mixed component analysis with XRD showed calcined Lusi could be added 10-60% in the portland cement, the highest compressive strength achieved from 10 %, 18 kgf/cm2 and 101,97 kgf/cm2 for 3 days and 7 days. While the XRD analysis showed that C2S, C3S, C3A, and C4AF components averaged 79.28% contained in blended cement.
