Abstract: Early-age cracking of concrete may influence the long-term durability of a structure. Cracking occurs when the tensile stress in concrete exceeds its tensile strength. Early-age stress development in concrete is influenced ...

Abstract: To effectively manage their inventory, transportation authorities are switching to nondestructive testing methods, such as the impact-echo method, to facilitate locating subsurface defects in reinforced concrete bridge ...

Abstract: Early-age cracking in bridge decks is a severe problem that may reduce functional life of the structure. The effect of lightweight fine aggregate on the cracking tendency of bridge deck concrete was evaluated using ...

Abstract: The maturity method accounts for the effect of curing temperature on the strength development of well-cured and consolidated concrete. This paper describes an investigation of the accuracy of the maturity method to estimate ...

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: When conventional concrete is used in congested drilled shafts, coarse aggregates may bridge between reinforcing bars, which may lead to segregation of the concrete between the inside and outside of the reinforcing cage. ...

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 effects of fluctuating temperatures on the setting times of concrete mixtures made with different water-to-cement ratios, supplementary cementing materials (SCMs), and SCM dosages are evaluated in this paper. Initial ...
