PROCEDE DE PREPARATION DE GRANULATS LEGERS
The present invention relates to a method for preparing lightweight clay-based aggregates, said aggregates being suitable for use notably in civil engineering works, in particular road uses, and construction. The invention thus firstly relates to a method for preparing lightweight aggregates comprising at least the following steps: a) a step of granulating a clay-based mixture, so as to obtain aggregates, b) a step of drying the aggregates obtained, so as to obtain dried aggregates, c) a step of heat treatment of the dried aggregates, said step comprising two successive substeps: i) a first substep of heat treatment carried out under a reducing atmosphere at a temperature T1 of between 900°C and 1200°C approximately, ii) a second substep of heat treatment carried out under an oxidizing atmosphere at a temperature T2 of between 1050°C and 1300°C approximately, and d) a step of cooling the aggregates.
