Poorly specified reentrant corners in partitions, precast users, and slabs, inappropriate reinforcement assortment and/or detailing, and restraint of users at risk of volume adjustments because of temperature fluctuations and humidity, deficiency of sufficient contraction joints, and inappropriate design and style of foundations, causing differential movement in the composition are all layout and detailing mistakes that can lead to unacceptable cracking.
Based upon these, Kjellsen and Jennings also proposed the identical definition of micro-cracks, which was regarded as fair physical interpretations of micro-cracks.
