Abstract: This study addresses the use of a stress-to-strength ratio as a failure criterion for thermal cracking. Restrained cracking frame specimens and accompanying match-cured concrete cylinders were tested to determine the ratio ...

Abstract: ASTM C 33 limits the amount of aggregate smaller than

Abstract: The Arrhenius equation is often used to characterize the progress of portland cement hydration for predicting in-place concrete temperature, strength, and other properties. To apply the Arrhenius equation, an activation energy (

Abstract: The effect of C3A polymorphism, the calcium sulfate source, and the addition of limestone on the hydration kinetics and rheology of cement pastes and their interaction with a lignosulfonate-based admixture were analyzed. ...
