Comparative Performances of Reinforced Beams Using Concrete Made from Crushed Sand and Fly Ash

The study deals with comparative performance of reinforced concrete beams using developed concrete made from crushed sand and fly ash, which were evaluated to be environmentally friendly. There are two main groups of developed concrete: the first is originated from matrix M1-T00 (using fine aggregate, no fly ash) having design compressive strength of 20 MPa; the second is originated from matrix M1-T00 (using fine aggregate, no fly ash) having design compressive strength of 30 MPa. Eight beams using eight concrete matrices were prepared with same dimensions of 150 × 150 × 900 mm (depth × width × span length) and same reinforcing bars and stirrups. All beams were examined using 3-point bending test. The bending resistances of investigated beams would be comparatively evaluated and discussed.
