Abstract

An experimental investigation was conducted to study both mechanical properties and the flexural strength of full-scale reinforced concrete beams constructed with both high-volume fly ash concrete—concrete with 70% of the cement replaced with fly ash—and conventional concrete (CC). The beams were tested under a simply supported four-point loading condition. The experimental cracking, yielding, and ultimate moments as well as deflection on ultimate load of the beams were compared with both the ACI 318-11 and Eurocode 2-05 provisions. Furthermore, the experimental flexural strengths of the beams were compared with both the modified compression field theory method and a flexural test database of CC specimens. Results of this study showed that the high-volume fly ash concrete beams had comparable flexural strength compared with the CC beams.
