A Logical Pozzolanic Index and Its Use in Concrete Proportioning

CODEN: JAIOAD

Abstract

A new approach to pozzolanic index is proposed. The proposed index (from 0 to 1) is based on the percentage of the pozzolan that reacts with lime. The index is logical in that it is a description of the level of reactivity of the pozzolan. The optimum pozzolan percentage for use with cement can be calculated using the index. An index can be estimated from pozzolanic reactions with lime or based on its contribution to the strength of concrete or mortar. A model for concrete strength incorporating the index is proposed that can be used to estimate concrete strength.
