EXPERIMENTAL STUDY ON SHEAR STRENGTH OF HIGH-VOLUME FLY ASH CONCRETE VERSUS CONVENTIONAL CONCRETE

Abstract eng:
An experimental investigation was conducted to study the shear strength of full-scale beams constructed with both high-volume fly ash concrete (HVFAC) – concrete with at least 50% of the cement replaced with fly ash – and conventional concrete (CC). This experimental program consisted of 16 beams (12 without shear reinforcing and four with shear reinforcing in the form of stirrups). Additionally, three different longitudinal reinforcement ratios were evaluated within the test matrix. The beams were tested under a simply supported four-point loading condition. The experimental shear strengths of the beams were compared with the shear provisions of both U.S. and international design codes (U.S. [ACI-318 and AASHTO LRFD], Australia, Canada, Europe, and Japan). Furthermore, statistical data analyses (both parametric and non-parametric) were performed to evaluate whether or not there is any statistically significant difference between the shear strength of the HVFAC and the CC beams. Results of these statistical tests show that the shear capacity of the HVFAC is greater than the CC for the beams tested in this investigation.
