Abstrakt:

The mechanical properties of concrete obtained from existing reinforced concrete buildings constructed many years ago were investigated. Concrete strength is used in seismic evaluations in Japan, however the concrete strengths obtained from the compressive tests were sometimes much lower than the specified concrete strength in the structural draft. It is investigated whether those properties of concrete were affected by deteriorations over long time periods, uncertainty of construction, or by other similar means. An improved method to estimate modulus of elasticity was also proposed and verified.
