Historic Mortars and New Repair Materials for the Architectural Heritage: Selected Papers from the 5th Historic Mortars Conference (HMC 2019)

Abstract

The 5th Historic Mortars Conference was held in Pamplona, at the University of Navarra, Spain, during June 19–21, 2019. HMC 2019 hosted more than 150 scientific communications from the five continents. The underlying theme was the interest in the Historic Mortars from multiple points of view: *Analysis of ancient materials, either in archaeological sites or in structures of the Architectural Heritage. *Studies on a wide variety of materials (such as renders and plasters, grouts, masonry materials and coatings) and compositions (earth-based mortars, gypsum plasters, hydraulic mortars, air lime mortars, mortars with pozzolans, natural and Roman cement mortars). *Research works on historic production, processing and application, including lime technologies. *Archaeometry studies. *Conservation issues: diagnosis, decay and damage mechanisms, case studies. *Preservation and repair materials: consolidation products, new mortars with improved properties, additives and admixtures, use of nanotechnology to obtain highly efficient repair products, preventive conservation. *Requirements for repair works and materials and adequacy of the testing procedures.
