    Prediction of FRCM–Concrete Bond Strength with

    1 day ago Fibre-reinforced cement mortar (FRCM) has been widely utilised for the repair and restoration of building structures. The bond strength between FRCM and concrete typically takes precedence over the mechanical parameters. However, the bond behaviour of the FRCM–concrete interface is complex. Due to several failure modes, the prediction of bond

    The concept of reinforcing materials weak in tension is delight-fully simple. Asbestos fibres are known to have been used almost 4,500 years ago to strengthen clay post. The use of continuous reinforcement is as old as reinforced concrete; the use of short, discrete reinforcing elements is relatively new, although the significance of the fibre geometry and the need to improve the
