Effect of different high alumina cements on the properties of self flow castable with distribution coefficient 0.21.

Abstract

The aim of this project is to study the effect of varying concentration of binding phase on the properties of high alumina self flow castable with distribution coefficient q fixed at 0.21 according to dinger-funk’s continuous particle size distribution model. The binders used were
CA-14 cement and polycem-75 cement. The XRD analysis of the two types of cement binder used is done. The varying binder concentration used in the four batches were 4% CA-14 cement, 4% polycem-75 cement,6% CA-14 cement and 6% polycem 75 cement respectively .The batches are prepared according to the conventional processing techniques and water is added till the self flowable characteristics is obtained .The batches were then dried at 1100C for 36 hours
and fired at 10000C and 16000C . The final products were then characterized for bulk density, volume shrinkage and cold crushing strength.
