Mar 12, 2019 When concrete is not cured properly, its durability, strength and abrasive resistance are affected. Due to inadequate curing, concrete develops plastic shrinkage cracks, thermal cracks, along with a considerable loss in the strength of the surface layer. When the surface of the concrete is not kept moist within the first 24 hours after the casting,
