Effect of alkali-silica reaction on bearing capacity of plain and reinforced concrete

This paper summarizes the results of an experimental investigation on the effect of alkali-silica reaction (ASR) on the bearing capacity of both small- and large-scale specimens of both plain and reinforced concrete Surface expansion and ultrasonic pulse velocity (UPV) were used to monitor the deterioration of the concrete specimens due to ASR. Empirical equations are proposed to predict the bearing capacity of ASR concrete subjected to symmetric and eccentric square, rectangular, or strip loadings. It can be concluded that the bearing capacity is more affected by ASR and change in loading geometry than by changes in any other variable.
