ABSTRACT

In the framework of the restoration process, the compatibility between the new repair mortars and the original components plays an important role in order to obtain an adequate performance in terms of mechanical and physical properties of the ancient materials. This chapter investigates the mechanical properties of pozzolanic mortars, in order to make a replica of mortars having physical, mechanical and chemical compatibility to the original ones. Due to the widespread use of pozzolanic mortar in Neapolitan constructions, a deeper knowledge about its mechanical properties would be very useful in determining retrofitting interventions on the architectural heritage. The present research has the aim to investigate, by means of laboratory tests, the mechanical properties of pozzolanic mortar in order to make a replica of mortars having physical, mechanical and chemical compatibility to the original ones. The brick fragments and tuff dust was produced in the laboratory by crushing, and subsequent sieving, clay bricks and yellow tuff stones.
