Resumo(s)
This paper investigates the mechanical and mineralogical characteristics of natural hydraulic lime
NHL3.5 (NHL) mortars with different% of lime replacement by metakaolin (MK) under different laboratory
and natural marine curing conditions.
Tests were conducted at different curing ages, using compressive and flexural strength tests and thermogravimetric
and X-ray diffraction techniques.
NHL mortars cured at high humidity levels in natural and artificial environments present interesting
results and some could be used in old masonries repair.
The incorporation of MK improves the NHL mortars strength, being this increase mostly associated to
the pozzolanic reaction.
