This reply sets out to justify the derivation of the equation relating strength to porosity originally proposed in the first paper. The approximation used is reasonable and a more rigorous approach is not necessary. It is also shown that the Mackenzie equation for the bulk modulus requires no amendm
We thank J. Baron and M. Buil for their reference to our work and for the interesting comparison they have made with their experimental results.
In our experiments, mortar samples were exposed to a CO2-enriched atmosphere (CO2-series) and to a CO 2 + SO2-enriched atmosphere (SO2-series). Because of the gas concentrations (0.7 vol.-% CO2; 0.06 vol.-% CO2) used, the dominant process consists in the reaction of CO 2 with the alkaline components
