Compressed concrete block with low mass per unit area comprising a raw clay matrix and associated methods

Abstract

The invention concerns a compressed concrete block comprising a raw clay matrix, a calcined metal oxide composition and aggregates, said compressed concrete block having a basis weight less than or equal to 600 kg/m2. The invention further proposes a preparation method (100) for a compressed concrete block having a basis weight 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 molds; applying (140) pressure to one surface of the molded mixture, preferably the top surface; removing (160) the compressed concrete blocks from the molds, so as to obtain a compressed concrete block with a basis weight less than or equal to 600 kg/m2.
