Testing of concrete in structures after thirty years of operation
Conclusions The concrete, subjected for over 30 years to wet conditions, showed an increase in the ultimate compressive strength by a factor of 3.5 with respect to the strength at 28 days.The ratio of the ultimate tensile strength to the ultimate compressive strength after 32 years under wet conditions is equal to 7%.The open porosity of the concrete after 32 years under wet conditions is equal to 7–8%.
