Rajendra Rajdev, Shalini Yadav, Rakesh Sakale

Abstract

This paper presents a comparison between two different procedures for the use of Fly ash (FA) in cement industry. The first which is very often used is by adding FA to clinker as in the manufacture of Portland Pozzolana Cement (PPC).The second which is recent trend is to process FA & by blending it with Ordinary Portland cement (OPC).Strength parameters are compared of both the types of cement. For the same target strength of the cubes OPC blended with Processed FA (PFA) proved to be more economical than PPC. Keywords : Fly Ash ,Blending, Ordinary Portland Cement, Portland pozzolana Cement, Processed Fly Ash.
