Strength Assessment in Portland Cement and Geopolymer Composites with Abrams’ Law as Basis

Abstract

In the recent past, there is growing interest to study the two modes of cementing of materials - i.e., conventional cement concrete and geopolymers in the same investigation to bring about their merits and demerits. As a complement to such studies, in this investigation, the analysis and assessment of strength development within the basic framework of Abrams’ Law are examined. It is interesting to note that the generalized Abrams’ Law holds valid both in the case of chemically bonded OPC and thermally bonded geopolymers in the analysis and assessment of strength development for the data generated by independent researchers. The pattern of strength development in conventional concrete and geo-polymers is the same. This is useful in re-proportioning cementitious composites irrespective of the binder.
