Abstract: Variations in the properties of fly ashes from various sources can lead to large variations in the performance of fly ash–blended cement systems. The current study combines analytical and numerical modeling approaches to ...

Abstract: Since fly ash is an industrial by-product, its properties are not controlled and, as such, are highly variable, leading to a high degree of variability in the performance of concrete. The feasibility of the blending of fly ...

Abstract: Fly ash (FA) increases the performance of cement concrete through pozzolanic reaction and microstructure development at later ages. FA is usually associated with lower early age compressive strength especially at higher ...
