ENDUIT POUR ABSORPTION ACOUSTIQUE
The invention relates to a plaster, in particular intended for acoustic correction, comprising: - at least one mineral binder, - aggregates, including: - light aggregates, the density of which is at most 700 kg/m3, in a content of at least 4% and of at most 20% by weight relative to the weight of the plaster, - heavy aggregates, the density of which is at least 1500 kg/m3, in a content of at least 50% by weight relative to the weight of the plaster, the weight fraction of aggregates having a size of at least 0.5 mm being at least 40%, said plaster having a density ranging from 700 to 1200 kg/m3 and an air flow resistivity ranging from 1x104 N.s.m-4 to 5x10 N.s.m-4.
