APPLI CATI ON S

Load-bearing walls for community centres, workshops, amphitheatres, gymnasiums, all premises requiring acoustic correction. (see Acoustic regulation pages 122 and 123). Self-bearing anti-noise architectural screens ensuring continuous phonic insulation as required in the "recommendations' in the specifications of the CETUR

CONSTRUCTION OF AN ANTI-NOISE WALL FOR A MOTORWAY

In order to resist to the force of the wind, cavities can be reserved during construction in order to permit pouring small posts in reinforced concrete which ensure stability (two 9 x 9 cm cavities). During the construction of the anti-noise wall for the "Western Freeway" in Toulouse, a stability test, supervised by SCCCTEC determined a permissible thrust due to wind of 300 kg/m³ (test conducted with a 9 x 9 cm post reinforced with 2TI0). (see diagram 4).
