Abstract: The influence of clinker replacement on temperature sensitivity of fly ash–blended cements was investigated at three realistic temperatures. Blends were prepared by replacing clinker with fly ash or quartz at two replacement ...

Abstract: Soluble alkalis play a vital role during early age hydration and strength development in cement. This study investigates the influence of alkali addition on the hydration, phase assemblage, and strength development in ...

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: A new micromechanical model is developed for the prediction of the elastic properties of composite materials with embedded spherical multicoated inhomogeneities of various sizes and types. The model is based on the n+1 ...

Abstract: Corrosion of steel in reinforced and prestressed concrete structures exposed to the marine tidal zone is a severe durability problem. This study used several indices related to moisture and chloride penetration into concrete ...

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 ...

Abstract: This paper presents a new approach to model the creep behavior of cement paste at early ages. The creep behavior is simulated by applying a time-varying generalized Maxwell model on the individual elements of a finite-element ...
