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.
To obtain the Normalised strength from the declared unit strength to BS EN 771-3 a correction for shape is needed, factors for which are given in the compressive strength test method (BS EN 772-1). The factors given in BS EN 772-1 generally require interpolation to establish the
