After rapid return of the bulged contents (7-8 days) in phase I, local compression and dressing changes are continued to promote the autogenous healing and growth of the defect.
In addition, the abdominal wall will have no incision after autogenous healing of the defect, and the umbilical region appears natural (Figure 2B).
Natural Healing and Autonomic Healing are classified as Autogenous Healing. However, Autonomic Healing can be classified as an active method because of the use of additional materials.

However, this autogenous healing
is limited to small cracks (<200 [micro]m) and requires the presence of water.
During most tours of concrete pipe plants, viewing stations are set up to allow participants to observe reinforcement cage production, cage delivery, pipe removal from the floor, rounding ring removal, the pipe production machine, pipe production cycle, removal of the pipe to kiln cars, tip out, deburring, stenciling, quality control, yarding, a three-edge bearing (3EB) test, and autogenous healing.
At a recent plant tour in Maryland, four units of pipe were intentionally cracked (to 0.01 and ultimate) a month earlier at the autogenous healing display.
of concrete in the drinking water industry.
These fine cracks can heal under favorable moisture conditions, to which Turner (1973) referred as autogenous healing. Several mechanisms of self-healing are proposed (Neville, 1995), i.e., hydration of the hitherto unhydrated cement, formation of insoluble calcium carbonate, and mechanical blocking by very fine material suspended in the water.
