This paper presents the results of an experimental study carried out within the National Institute for Research, Development in Constructions, Urbanism and Sustainable Territorial Development URBAN INCERC, on a system of walls made of ACC blocks, according to the standard SR EN 771-4 [8], having a density of 480 kg/m 3 and standardized compressive strength of 3.5 N/mm 2 , using mortar type binder class M2.5 with compressive strength of 2.5 N/mm 2 . It was exposed to the action of standardized fire for a period of 220 minutes, after 10 days from the execution of the masonry. The results showed that, following the tests on the burned samples, extracted from the wall subject to the test, the standardized unit compressive strength decreased by 54%.
