Abstract
This research determines the comparison between the flexural behavior of Normal Concrete (NC) beams and High-Volume Fly Ash Self Compacting Concrete (HVFA-SCC) beams. The research data was obtained from full-scale beam tests using four-point loading. Tests were carried out on 6 NC and 6 HVFA-SCC beam specimens with dimensions of 150 mm × 250 mm × 2000 mm. The test specimens varied with main reinforcement of 12 mm, 16 mm, and 19 mm diameter. The results of the studies show that the crack patterns of the NC and HVFA-SCC beams are almost identical to those of the flexural failure mode, while the HVFA-SCC beam has greater ductility than the NC beam. The nominal flexural strength (Mn) of HVFA-SCC beams can be calculated using the Mn formula in ACI 318-19.
