✅Types of Concrete Defects - Causes, Prevention✅ 1. Cracking Various reasons for cracking are improper mix design, insufficient curing, omission of expansion and contraction joints, use of high slump concrete mix, unsuitable sub-grade etc. Prevention, use low water - cement ratio maximize the coarse aggregate in concrete mix, admixtures containing calcium chloride must be avoided. 2. Crazing Crazing also called as pattern cracking or map cracking is the formation of closely spaced shallow cracks in an uneven manner. Crazing occurs due to rapid hardening of top surface of concrete due to high temperatures or if the mix contains excess water content or due to insufficient curing Pattern cracking can be avoided by proper curing, by dampening the sub-grade to resist absorption of water from concrete, by providing protection to the surface from rapid temperature changes. 3. Blistering & Delamintaion Blistering is the formation of hollow bumps of different sizes on concre...
