*Senior Teacher,
Investigation of some characteristic values of concrete in reinforced concrete elements is necessary. This survey makes it possible to assess the actual work of concrete in the design of reinforced concrete. It is recommended to measure the width of crack opening in reinforced concrete elements in the places of maximum opening and at the level of stretched reinforcement. The length of the cracks is measured using a millimeter ruler, and the width of the opening is measured with a template thickness gauge, graduated loupes with 4x magnification or measuring microscopes with 24 x magnifications.
