A concrete beam with internally unbonded FRP tendons exhibits greater deflections, fewer flexural cracks, and lower ultimate loads than a beam with fully-bonded FRP tendons, as shown in Fig. 2.6 (Saafi and Toutanji, 1998; Lees and Burgoyne, 1999; Toutanji and Saafi, 1999).Possible reasons for such a relatively low load-carrying capacity are attributed to the slippage of unbonded FRP …

While diamond grinding is effective at leveling an uneven surface, it is not an efficient method for flattening a non-flat surface. If your concrete area features a crack or damaged section that is creating a protrusion or tripping hazard, the amount of grinding necessary to flatten the area will cost more in equipment and material costs, and likely result in unevenness in other areas as a …

Stirrups or transverse reinforcement resist the shear stresses in the beam and hold the longitudinal reinforcement in place. Stirrups prevent the shear, flexural and torsional cracks which occur at 45 degrees to the main axis of the beam. Stirrups also add to the shear strength of concrete. They are closely placed near the supports of the beam ...
