Fatigue tests were conducted on two different light-weight aggregate concretes, one proportioned for a high strength and the other for a low strength. Specimens of approximately the same age were tested at stress levels of 40, 50, 60, 70, and 80 percent of the ultimate static compressive strength of the respective mixes. Within the limits of the investigation, the fatigue behavior of high strengthlightweight concrete was similar to that of low strength lightweight concrete. In addition, the fatigue behavior of the lightweight aggregate concrete appears to be similar to that found for a normal weight concrete in a previous study.
