Effectiveness of the Grout Injection on Rubble Stone Masonry Specimens: An Experimental Research


Abstract eng:
The paper presents a research work developed aiming to study the improvements introduced by the grout injection strengthening technique for the structural rehabilitation of old buildings, with rubble stone masonry walls. First, cyclic shear tests were performed on two unstrengthened rubble stone masonry specimens which were built with hydraulic lime mortar and traditional limestone. Then, a specific grout, based on hydraulic lime and cement, was developed taking into account the characteristics of some rubble stone masonry walls existent in old buildings in Lisbon, Portugal and aiming to strengthen the masonry walls. Afterwards, the specimens previously tested were strengthened by this injection grout and the cyclic shear tests were performed again. The results obtained showed that this strengthening technique was successful in allowing the damaged specimen recovered the initial characteristics and in successfully restore their load carrying capacity.
