Self-healing concrete can heal itself from cracks and other minor imperfections and thus to prolong the life of the materials and structures. The critical width for crack healing is about 0.2 mm for concretes observed and proved by many researchers. After several generations, the self-healing additives are now stronger and more effective. To apply these products to real concrete structures, the fatigue behavior of self-healing concrete needs more investigation. Shear, compressive fatigue tests were conducted to exam the structural performance of new type of self-healing concrete. |
