AUTOGENOUS SETTING OF NON-HYDRAULIC LIME MORTARS BY MEANS OF MICROBIAL CARBONATE PRODUCTION

摘要

The present invention relates to the usage of micro-organisms to accelerate carbonation and to increase the compressive strength of non-hydraulic lime mortars. The micro-organisms of the present invention metabolize nutrients within the mortars in order to produce CO2 which results in accelerated CaCO3 formation and hence increased strength of the mortar. The invention further encompasses non-hydraulic lime mortars comprising micro-organisms and relates to a process to fabricate such lime mortars.
