Self-healing on natural hydraulic lime mortars

Project description

Improving the self-healing capacity of natural hydraulic lime mortars

Interventions for the conservation of civil and architectural heritage sites require the use of materials that are largely compatible with the original materials, such as natural hydraulic lime (NHL) mortars. Since these interventions must be sustainable, solid and resistant, self-healing capacity of NHL mortars is instrumental. The EU-funded HeaLime project proposes a new measurement method for cementitious materials and will systematically qualify a combination of several variables in the scheme of the performance of the healing capacity. The new method consists of an adaptation of the EMM-ARM technique that characterises the stiffness evolution of cementitious materials, for measurement of the self-healing of NHL mortars in service. Simultaneously, different materials will be combined to develop improved NHL mortars for self-healing.
