description

This work deals with the composition and the state of conservation of the concrete of two hangars designed and built by Pier Luigi Nervi in 1940-1941. The interest in this project is related both to the use of on site prefabrication for so large structures (45x55 m plan) and to some peculiarities of the mix design, in particular the aggregate/binder ratio and the lithological composition of the aggregates. The study has been performed by means of X ray diffractometry, optical microscopy in trasmitted light on thin sections, ionic chromatography and carbonation tests. The twofold aim is to assess the conservation condition of concrete after 67 years of ageing in a marine spray environment and to relate the degradation phenomena both to mix design and to pouring operation.
