(i) Concrete is used in a variety of applications from high-rise constructions to road pavements, bridges and floor slabs. Engineers will specify the strength of concrete mixes needed for each specific application. Compressive stress testing is carried out on test samples from concrete batches for purposes of quality control. In the space provided, sketch and label the fracture pattern of the concrete test piece after a compressive test. rustgaib edt nog henbo quinteto odsledal bu gain 500 Calentate the ritional t die beh demos of bebe si gnioroinien fest 2 olid Tuledno bohoqquz od to dinaste sliznat sbig of hobson axed Isola GAOI (ii) nd

Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.
