Abstract Indonesia oil sand silt was used as calcareous raw material to produce portland cement clinker. Effects on clinker burning and cement properties have been studied and compared with limestone. Results showed that, Indonesia oil sand silt as calcareous material, could meet the requirements of cement raw meal preparation. However, the raw meal burnability was poorer and the content of fCaO in clinker was higher than that using limestone as calcareous raw material. With the increase of burning temperature, the content of fCaO in clinker became close, and the clinker mineral formation was good, the initial and final setting time was relatively long, however, the interval between the cement initial and final setting time was short. When the proportion for the oil sand silt and limestone was each 50%, the raw meal burnability became better, the fCaO content in clinker was lower, the normal clinker mineral was formed, and the cement final setting time was shortened. The clinker strength of each age was improved, especially for 100% oil sand silt as calcareous raw material, followed by 50% oil sand silt and 50% oil limestone. The oil sand silt can partially or wholly replace the limestone to produce cement.
