Abstract

The current Portland Fly Ash cement is widely used in both construction and oil well cementing process. This paper will focus on cement for oil well cementing process only. Volcanic tuff, which is consolidated volcanic ash largely made up of silicon dioxide and calcium oxide, can be used as a substitute for Portland cement, or as a supplement to it. The materials which make up fly ash are pozzolanic, meaning that they can be used to bind or cement materials together. It will increase the long term compressive strength, reduce fluid loss, good resistance to sulphate attack , less C02 emission ,less permeable and more environmental friendly compare to coal fly ash. This project is about doing research using tuff in La win, Perak to generate Portland Flyash cement. Lawin Tuffis a type of volcanic rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption. The current fly ash use in Portland cement is from industrial burning of coal and it contains heavy metals and radioactive mineral. Thus, this project is hoped to use natural fly ash from tuff to generate Portland Fly Ash cement that can be used in oil well cementing. Several tests are carried out to determine the best proportion of tuff used to mix with Portland cement and generate best results.
