This research explores and focuses in the mechanical behaviour of lime mortars with dried fibers of white opuntia cactus, as an addition for its use in restoration of ignimbrites masonry in architectural heritage buildings. Local regulations indicate that the cementing material must be a mortar-based lime, and some additions referred to in historical literature should be used. This work recreates the mortars making in the old style.
Lime mortars were fabricated with industrial building grade lime, river quartz sand aggregates (lime: sand 1:3 proportion), drinking water, and additions of dried white cactus opuntia fibers. Specimens elaborated for testing compression (5cm x 5cm x 5cm), tension (briquettes 1.5 cm x 2.5 cm x 7.5 cm), flexural strength (4cm x 4cm x 16 cm) at the ages of 7, 14, 28, 35, 473 and 504 days. All the collected data were compared vs. a control mortar without such additions.
Keywords: Masonry, mortars, cacti additions, lime.
