Mortar for covering structural elements, with high acustic performance levels

Abstract

[ES] Con la incorporación de un mortero de revestimiento, a base de cemento y coque granulado con diámetros de partícula comprendidos entre 1 y 6 mm, en elementos constructivos como el trasdós de fábricas de ladrillo, se consigue un doble efecto de incremento de aislamiento acústico. Este efecto se debe al aumento de la masa por la proyección del mortero y a la absorción acústica como consecuencia de la red porosa que posee el material aplicado. Las prestaciones acústicas conseguidas superan a las de la misma configuración de doble pared per con incorporación de lana mineral en la camara, y también a la de mortero convencional de cemento y arena. También, los morteros de revestimiento en cualquier caso, son necesarios para garantizar la impermeabilización de fábricas de ladrillo en exteriores. Por otro lado, el menor espesor del mortero de coque (15mm) con respecto al de la lana mineral (50-80)mm), reduce el espesor total del cerramiento y aumenta, por tanto, la superficie útil de la edificación.

[EN] The incorporation of a covering mortar based on cement and granulated coke with particle diameters between 1 and 6 mm, into structural elements such as a brickwork extrados, gives a dual effect of enhanced acoustic insulation. This effect is due to the increase in the mass by the spraying of the mortar and to acoustic absorption as a consequence of the porous network of the material applied. The acoustic performance levels achieved exceed those of the same configuration as a double wall but with the incorporation of mineral wool into the cavity, and also that of conventional cement and sand mortar. Furthermore, covering mortars are in any event necessary to guarantee the external leaktightness of brickwork. Moreover, the fact that the coke mortar is thinner (15 mm) than mineral wool mortar (50-80 mm) reduces the total thickness of the elevation and thereby increases the useful surface area of the built structure.
