Abstract
Typical C16/20 concrete class has been studied in an accelerated carbonation experiments carried out under high CO2 concentration. The 100x100x100 mm cube specimens, prepared with natural aggregates and recycled aggregates, were stored for 28 days in water and have been tested (physical-mechanical characteristics). After 60 days of accelerated carbonation conditions test, in a protected environment - 50% carbon dioxide concentration, temperature 25 ° C and humidity 75-80%, the specimens were cleaved to determine the carbonation depth by phenolphthalein test on the faces in the splitting zone, measuring the minimum and maximum carbon dioxide penetration values. Correlation was made between the compressive strengths obtained for the studied specimens and the carbonation depth after the accelerated carbonation experiments in the protected environment.
