Abstract(s)The objective of this work is to evaluate the acoustic performance of beam and pot slabs with regularization layers made of lightweight concrete. The study consists on the analysis of the acoustic behaviour of three types of solutions, through the execution of "in situ" measurements for the determination of the airborne sound insulation index and of the impact sound insulation index. The studied elements have the same support element (concrete slab), but regularization layers made of different materials. The regularization layers studied were: concrete with granulated expanded polystyrene, concrete with expanded clay aggregates and cellular concrete. The acoustic performance of the three slabs is evaluated and compared with the performance of conventional solutions in way of evaluating their potentialities.
