Abstract (en)

[origin: CA3224273A1] The invention relates to a compressed concrete block comprising a raw clay matrix, a calcined metal oxide composition and aggregates, said compressed concrete block having a mass per unit area of less than or equal to 600 kg/m2. The invention also relates to a method for preparing (100) a compressed concrete block having a mass per unit area of less than or equal to 600 kg/m2, said method comprising the following steps: - mixing (110) a raw clay matrix, a calcined metal oxide composition, aggregates and water; - placing (120) the resulting mixture in moulds; - applying (140) pressure to one surface of the moulded mixture, preferably the top surface; and - removing (160) the compressed concrete blocks from the moulds to obtain a compressed concrete block having a mass per unit area of less than or equal to 600 kg/m2.
