Natural hydraulic lime mortars with ceramic residues for masonry

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


In Portugal natural hydraulic limes have recently been formulated to accomplish EN 459-1:2010 requirements and, for that reason, knowledge on mortars with that particular binder is still recent. With the downturn of the building sector and sustainable practices awareness, many ceramic factories and construction sites have had to reconsider the management of their wastes. Ceramic wastes were often used in the past as pozzolans of air lime mortars. Bearing these considerations in mind, mortars with low content of a natural hydraulic lime and additions of two ceramic wastes were formulated, cured in laboratory conditions and exterior environment and characterized by destructive and non-destructive methods. Aspects related to workability, mechanical resistances, water absorption, drying and resistance to sulphates´ attack are analysed. The viability and drawbacks of the addition of ceramic wastes to low binder content natural hydraulic lime-based mortars to be applied on masonries are highlighted.
