Lightweight coating mortars for buildings restoration
Original language description
In this paper, crushed lava-based aggregate was used in mortar mix composition as a full silica sand replacement to improve thermal properties of mortar fulfilling also other physical, mechanical and technical requirements. As a binder, natural hydraulic lime was used. Consistency of fresh mortar mixes was characterized by flow table test. The casted samples were cured for 28 days in a high relative humidity environment to avoid cracking. For the hardened mortar samples, structural, mechanical, and hygric properties were tested. Heat transport and storage parameters of the developed mortars were measured in dependence on moisture content, from the dry to fully water saturated state. The use of lava granulate led to the mortar’s increased porosity, improved mechanical strength, lower water absorption, and significantly better thermal performance compared to the reference mortar with silica sand. The newly developed lightweight mortar met the technical, compatibility and performance criteria on rendering mortar and was found well applicable for repair of old and historically valuable buildings.
