Crazing Cracks are cracks on the surface in a hexagonal pattern. It occurs due to shrinkage, not enough curing, acidic water used, and weathering actions.
Measures taken to avoid crazing Cracks:
1)Do sufficient curing during construction.
2)Use sand with 75 mm size particles. Remove all particles greater than 75 mm in size by sieving.
3)Proper workability concrete used.
