Summary: Restraint to restrained shrinkage of concrete is arguably the most common cause of unsightly cracking impacting the serviceability of structures. In chloride environments, these cracks can lead to time-dependent steel reinforcement corrosion. Using crystalline admixtures as chloride transport-mitigating agent owning its hydrophilic nature, this project aims to develop an intrinsic self-healing concrete for rapid healing of retrained shrinkage induced cracks and preventing corrosion of reinforcing steel due to concrete cracking. The outcomes of this project will drive the advances in developing and applying crystalline admixture-based self-healing concrete to improve durability and serviceability of concrete infrastructures.
