Abstract

The research line MOdihMA proposes to improve the innovative techniques recently developed to measure different parameters related to water content in masonry, that has an important role in the damage of historical buildings. The MOdihMA (MOisture detection in historical MAsonry) research involves experts from many research laboratories. The project has been started in 2009 and was firstly presented to the public in a conference in 2011. The first objective of this project is to compare the effectiveness of the different methods in understanding how the quantitative data obtained are directly related to water content. The second objective of the MOdhiMa project is to compare the ability of the different techniques to map water as a function of its location and depth within the masonry structure, both on macro and micro-scale. The experimental results on a case study were recently published in the scientific literature. A selection of these innovative techniques recently had an application on the “Sala delle Asse” in the Sforza Castle in Milan. The hall is celebrated for the decoration of the vault with plant twines holding the coat of arms of the Sforza family and plaques with mottos. A monochrome painting, attributed by critics to Leonardo was painted on one of the walls. . Recently Milano Municipality defined the plan of diagnostics for detecting the causes of the increasing damage on the painting and the poor conditions of conservation of the vault. Unilateral NMR, SUSI, IR Thermography, gravimetric and chemical tests were applied for mapping the moisture distribution in the bottom of the northwest wall. NMR and SUSI provided a suitable number of measurements that allowed to obtain a precise map of the distribution of moisture content (MC) in the wall under investigation. The comparison with the results of the standardized techniques confirmed the low moisture content distributed in the masonry. The annual microclimate monitoring will provide more data for refining the hypothesis of the cause of damage, and after the first six months is already possible to identify some risk factors for the conservation of the painting.
