The construction industry must achieve quality control and quality assurance up to the selected level. It is indisputable that construction work is of high quality. Any means must employ to achieve it. Due to construction defects, cracks are commonly observed in the structure.
Poor construction activities and lack of attention from contractors result in defective work, which increases construction costs. Engineers and owners bear the burden for this as well. These rectification works require additional time, which delays projects.
Types of Poor Construction Practices
Addition of Fresh Water on Construction Structure
A common construction error is adding water to concrete to make it more workable; this reduces concrete strength and increases shrinkage and settlement. A shrinkage crack and plastic settlement crack will eventually form. Compared to the latter, which is primarily diagonal, the former is isolated or individual.
Offset Strength Reduction by Increasing Unnecessary Amount of Cement
As a result of adding unnecessary cement to the concrete element, temperature differentials would also increase between the interior and exterior sections. Cement content increases thermal stress as well as drying shrinkage stress. Concrete cracks because of this.
