A maturity approach to estimate compressive strength

2018-1-1  It was found that the compressive strength of the carbonated concrete blocks reached the highest level when the RH was at 49.7%. When the RH was at 99.7%, it decreased the compressive strength significantly. This is because the chemical reactions between CO 2 and the cement components are initiated with the dissolution of CO 2 in water.
