Project description

Providing lime mortars with an early strength is usually done through expensive and/or toxic chemicals. Here we propose obtaining rapid hardening of lime mortars through bacterial CO2 production and calcium carbonate precipitation. Also, the autogenous self-healing capacity of lime mortars will be studied and bacteria will be added into lime mortar, to induce CaCO3 precipitation in occurring microcracks.
