College of Engineering, University of Diyala
discussed a master dissertation on the shear behavior of reinforced concrete
beams reinforced by near-surface fixed bars with geopolymer adhesive by the
postgraduate student, Mr. Mohammed Ali Abdullah.
The dissertation aimed at studying the
practical and theoretical aspects of the shear behavior of reinforced concrete
beams reinforced by near-surface fixed bars with geopolymer adhesive as an
alternative to epoxy, which is cheaper, environmentally friendly, safe and
sustainable compared to epoxy.
The dissertation highlighted that the
maximum load-bearing capacity of concrete beams reinforced by near-surface
fixed bars with geopolymer and epoxy adhesive increased by up to (118 and 117%)
respectively when compared to the unreinforced model, thus geopolymer can be
used as an alternative to epoxy adhesive in strengthening the shear of concrete
beams by near-surface steel bars.
