MORISAL
MORtars with mixed-in Inhibitors for mitigation of SALt damage
Salt crystallization is a common cause of weathering of building materials worldwide. In particular, mortars (including plasters and renders) are recurrently damaged by salt crystallization and need frequent replacement, resulting in high costs. The quest for new, sustainable solutions, improving the service life of renovation mortars is the response to a severe problem met in practice. The proposed research aims at the development of renovation mortars with an improved durability with respect to salt crystallisation, thanks to the use of crystallization inhibitors (i.e. molecules or ions capable to modify salt crystallization making it less harmful) mixed in the mass.
In order to achieve this, fundamental issues (related to the development of crystallization pressure in the pores of a building material) and aspects related to the performance of the product will be investigated. Three universities, a research centre, a mortar producer and branch organizations have joined their forces for the achievement of this ambitious goal.
