Epoxy resins are widely used in structural repairing and strengthening work, but most of them typically require primer works and are vulnerable to water. To overcome such limits, a non-shrinkage chemical grout (NCG) has been developed in this research, which provides a strong chemical bond strength utilizing Silanol/Si-OH. The material characteristics of the NCG were investigated from experiments and the applications of non-shrinkage chemical grout were also provided. The experimental investigation indicates that NCG has much improved performance compared to a typical epoxy product, which implies that the NCG can be widely used for repairing and strengthening work.
