Abstract:
This paper presents results from an experimental investigation in which the shear capacity of eight reinforced concrete beams affected by alkali silica reaction (ASR) were investigated under static and cyclic loading. The results of the ASR beams was compared to eight identical reinforced concrete beams that were not affected by alkali-silica reaction. Two concrete mixes were used, one mix allowed the alkali-silica reaction to develop and is referred to as Mix A. The second mix did not allow the ASR reaction to take place and is referred to as the control or sound Mix C. The results show that the ASR enhanced the shear capacity of reinforced concrete beams and ultimately lead to increases in their lifetimes.
