The paper presents the results of an experimental investigation that was carried out to evaluate the effectiveness of key performance characteristics of concrete made with OPC, inter-ground PPC and site mixed OPC and fly ash. A host of properties of concrete were studied.
Both drum mixer and pan mixer were used in the study.
The results of, the investigations indicate that the performance of concrete using inter-ground PPC is much better than those using OPC and site mixed fly ash plus OPC.
The inter-grinding of fly ash with clinker and gypsum maximizes the pozzolanic potential of fly ash with more consistent product with good control on variability, leading to a better performance of PPC concrete.
