Abstract:
This presentation is part on an extensive research program into the effect of several parameters on the shear behaviour of beams made with recycled concrete aggregates. Eight beams were designed to fail in shear. Three values of shear span to depth ratio were considered: 2.5, 3.5, and 4. Two replacement ratios of coarse aggregates were studied: 50% and 100%. Beams made with natural aggregates were also cast to serve as control beams. Mix design and the longitudinal reinforcement ratio of 1.04% were kept the same for all test beams. Deflections, concrete compressive strains, steel strains, crack patterns, ultimate shear capacity; and failure modes were all observed and analyzed and the relevant conclusions were drawn. ACI Code provisions for shear strength prediction were evaluated against test data.
