Chemical Additives. These are used to: Reduce the construction cost; Overcome emergencies at concrete operations. …For FRP to develop and transfer the design stresses at the bond line, the concrete substrate should possess sufficient strength to transfer these stresses. And, in order for the concrete to provide the minimum bond strength of 200 psi (1.4 MPa) specified by ACI 440.2R, the compressive strength of concrete f'c must be more than 2500 psi (17 ...
