Abstract: In Mexico, the restoration of lime mortars is developed with regional materials and mostly prepared and evaluated on site. To assure the effectiveness of the local pozzolanic material, qualitative, economic and brief tests can be developed in situ. The measurement of properties such as setting time, water absorption, resistance to compression and resistance to salt attack can provide tools to analyze compatibility with historic mortars and the correct operation of restoration procedures. In contrast to usual practices of Built Cultural Heritage restoration in Mexico, where traditionally a minimum of 10% cement is added to achieve some of these properties, formulated lime mortars (air lime + pozzolans) are a compatible option for historic mortars, generating sustainable practice, reducing environmental impact, promoting local consumption and safeguarding traditional constructive culture.
