Lime mortars containing ceramic material as pozzolan

Lime mortars have been indicated for restoration and conservation interventions in historic buildings, however, the slow hardening of these mortars does not favor their use and dissemination in construction areas. The inclusion of pozzolans improves these properties, and although the results achieved are not close to those found in conventional cementitious mortars, they are seen as compatible materials for restoration services, since they present moderate mechanical responses and chemical compatibility. This chapter aims to show the impact of different pozzolans on fresh and hardened lime mortar’s properties, including mechanical, rheological, and microstructural properties. In addition, an overview of historical mortars is presented.
