This project carried out on Portland cement using high calcium limestone, and other minor raw materials such as clay and iron ore. The raw materials were obtained from a local rock in Lenggong in Perak, Malaysia. Composition of raw materials and mineral phase were investigated or tested by XRF. Portland cement is primary construction materials widely used in oil and gas wells specially class G Portland cement. Portland cement at least to comply with the standards set by the American Petroleum Institute (API). Chemical compositions of limestone, clay, iron ore and raw materials were determined. Modulus of mixture of raw materials was fixed in IM is 1.7, SM is 2.4 and LSM is 9.4. Raw materials were crushed and ground to fine powder to form a mixture raw material and then put in furnace where it is heated and burning to form Portland cement clinker. From the expriremmtal results, the four main Portland cement are CS3, CS2, C3A and C4AF. iii
