The application of reinforced concrete in modern construction ranges from foundations, columns to various aperture beams, ceilings, roofings, dams and reservoirs. Depending on the type of impact, a reinforced concrete construction has to meet certain strength and quality requirements. The durability of a reinforced concrete construction is influenced to a great degree by the technological solutions selected, physical and chemical processes involved, as well as the ambient environment during the early hardening stage of concrete, any of the above mentioned can cause damage in concrete. Physical and chemical processes in concrete tend to occur at different stages of hardening, therefore, their effects on concrete differ. Quite often, follow- ing the removal of the formwork, cracks can be observed on the surface of a reinforced concrete construction which could have been caused by the above mentioned factors. Early damage in reinforced concrete constructions is detrimental in terms of their further exploitatin [1,2].
