Durabilità degli interventi di recupero di elementi di facciata in calcestruzzo: il progetto esecutivo e gli aspetti procedurali di cantiere

This paper illustrates the major criteria for designing and performing repairs on reinforced concrete facade elements, as identified through experimental investigations of repair durability and work at a pilot site. The experience gained during work at the pilot site demonstrated the advisability of approaching repair projects case by case, analyzing the specific deterioration conditions, performing preliminary investigations, and planning repair work on an ad hoc basis for all stages, from selecting the products to be used to specifying application methods. The memory, in particular, illustrates correct design criteria for each stage of repair work, and identifies the methods for monitoring and inspecting repairs that are most appropriate from the standpoint of durability. Particular attention is addressed to the problems involved in analyzing existing structures, preparing substrates using alternative techniques, treating reinforcing metal, applying repair mortars, surface protection and finishes, monitoring repair work and performing final inspection.
