  • IB 1002 Autogenous Healing of Concrete Pipe

    Evidence of autogenous healing is a whitish substance forming along the crackline. Simply stated, autogenous healing is the ability of concrete to heal itself. In the presence of moisture, concrete extrudes calcium hydroxide which, upon exposure to the atmosphere, is converted to calcium carbonate (limestone) which seals the crack.
