Abstract:

In this research study, the fatigue durability of concrete was reviewed, a reproducible flexural fatigue test was developed, and the flexural fatigue durability of selected unreinforced concrete structural lightweight concretes was determined. Also, relationships between flexural fatigue durability and freeze-thaw durability of selected concretes were established. Fatigue tests were conducted on unreinforced concrete prism specimens of three lightweight concretes and one regular weight concrete. Two of the lightweight concretes and the regular weight concrete were tested in a moist condition, and one lightweight concrete was tested in a dry condition. In the fatigue tests, all specimens were subjected to repeated sinusoidal stress cycles at the rate of 697 cpm. The fatigue stress levels were determined as a percentage of moduli of rupture (center point loading) of identical prism specimens. All concretes were cured for a minimum period of 28 days prior to testing.
