This research is aimed at developing a methodology for the emergency stabilization and restoration of historic buildings damaged by the 2009 Abruzzo earthquake, through on-purpose modified injection grouts based on hydraulic binders. Several portions of multi-leaf stone masonry walls from buildings in the towns of Onna, Tempera and Sant’Eusanio Forconese, all located in the province of L’Aquila, were selected for carrying out injection tests with six grouts. Before and after injection, a comprehensive experimental program, including chemical and microstructural tests on original and repair materials and mechanical tests on the masonry walls, was performed. The present contribution describes the tests carried out at the various levels and discusses the main results obtained.

Abstract

This research is aimed at developing a methodology for the emergency stabilization and restoration of historic buildings damaged by the 2009 Abruzzo earthquake, through on-purpose modified injection grouts based on hydraulic binders. Several portions of multi-leaf stone masonry walls from buildings in the towns of Onna, Tempera and Sant’Eusanio Forconese, all located in the province of L’Aquila, were selected for carrying out injection tests with six grouts. Before and after injection, a comprehensive experimental program, including chemical and microstructural tests on original and repair materials and mechanical tests on the masonry walls, was performed. The present contribution describes the tests carried out at the various levels and discusses the main results obtained.
