<p>1. Method for the carbonatising after-hardening of moulded bodies of hydrothermally hardened lime-silica masses by the action of CO2 -containing gas with a CO2 -content of at least 10% on the hardened moulded body, both the moulded body as well as the gas having an increased temperature, characterised in that the moulded bodies after leaving the hardening vessel are treated at a temperature of at least 100 degrees C with waste gases from pressure of less than 2 bar and the time of treatment is between 30 and 60 minutes.</p> |
