Abstract
A settable mixture comprising magnesium oxide, magnesium chloride, water, resiliently compressible fibers, and a filler material produces a cement with high strength and excellent sound attenuation properties, avoiding the expansion properties observed in comparable prior art mixtures. The mixture may be used in a method of manufacturing a sound insulating floor construction on top of a floor base (1) and within confinement walls (2), the method comprising applying on top of the floor base a layer of soft, resilient mats (3), arranging along the confinement walls a spacer list (4) comprising a sort, resilient material, pouring on top of the mats the mixture, leveling the top surface of the mixture, and allowing it to set to form a solid slab (5).
Claims11
A method of manufacturing a sound insulating floor construction on top of a floor base and within confinement walls, comprising the steps of:
- applying on top of the floor base a layer of soft, resilient mats,
- arranging along the confinement walls and at least partially above a top side of said layer of mats a spacer list comprising a soft, resilient material,
- pouring on top of said layer top side a mixture comprising magnesium oxide, magnesium chloride, water, resiliently compressible fibres and a filler material, said filler material comprising at least one ingredient selected from a group comprising an expanded material, expanded clay aggregate, expanded glass, expanded polymer and pumice,
- leveling the top surface of said mixture, and
- allowing said mixture to set to form a solid slab.
A sound insulating floor construction, comprising a layer of soft, resilient mats, a spacer list arranged along a margin of said layer of mats and extending at least partially above a top side of said layer of mats, and a slab formed by pouring on top of said layer of mats and within said spacer list a mixture of ingredients comprising magnesium oxide, magnesium chloride, water, resiliently compressible fibres and a filler material, said filler material comprising at least one ingredient selected from a group comprising an expanded material, expanded clay aggregate, expanded glass, expanded polymer and pumice, leveling a top surface of said mixture, and allowing said mixture to set.
