A Study on the Modified Cement-Based Crack Injection Materials

Human constructed harbours are large infrastructure projects that use cement to reinforce embankments and build protective walls. However, like all concrete building projects maintenance is required. Cracks form and if left unattended will grow, eventually leading to a dangerous situation where a structure's integrity is compromised. As a result, the concrete repair industry, particularly in relation to marine infrastructure, is a large one and various mixtures of cement and other materials are designed to fill these cracks. Researchers at the National Taiwan Ocean University in Taiwan are now investigating the best ways to design injectable materials to repair cement cracking in a marine setting in order to develop new cement recipes that will work in marine environments and protect vital harbours from deterioration.
