Abstract

Blended cement by definition is cement consisting of an intimate and uniform blend of Portland cement and pozzolanic material. Blended cement is produced by intergrinding Portland cement with the other materials. For a long time,petroleum and cement industries were conducting investigations and field studies to improve compressive strength, thickening time, fluid loss and also microstructure. So, the objective of this project is to create new blended cement that improves compressive strength, thickening time, and fluid loss. With this new blended cement, a lot of improvements towards environment, society, petroleum industry and also in terms of financial benefits. Materials that used in this project were oil-well cement class G, silica fume and fly ash class C. Five samples of model have been made for experimenting in order to compare with the conventional cement. The compositions were starting with constant 50% for cement class G and 0% for silica fume and 50% fly ash class F. All these experiments will be conducted in the cement lab and supervised by lab technicians. After gaining the results, better composition that leads for improvements than conventional cement will be chosen based on compressive strength testing, thickening time and fluid loss. The compressive strength was tested with compression machine. Based on this research, blended cement will be produce using HPHT curing chamber, stirred fluid loss tester and consistometer. The results showed blended cement (sample 4) with composition of 50% cement class G, 37.5% silica fume and 12.5% fly ash class F results in higher compressive strength, better thickening time and fluid loss compared to other. In addition, blended cement is proven cheaper in term of cost compared to conventional cement since the materials are available abundantly. In conclusion, this project can provide new information to improve the quality of blended cement
