Study of Atmospheric Corrosion of Reinforcement Steel in Havana, Cuba

The atmospheric corrosion of reinforcement steel phenomenon has been frequently investigated under accelerated exposure, throughout diagnostic studies on site and no so much study under natural environmental conditions using probes with different concrete qualities. An exposure site placed at 20 m f...
