Abstract

A mortar composition, in particular a leveling mortar composition, comprises or consists of: a) 10-50 wt.% of a hydraulic binder, b) 10-25 wt.% of lightweight aggregates, c) 30-50 wt.% of further aggregates which have a particle density that is higher than the particle density of the lightweight aggregates, d) 0.5-5 wt.% of a polymer.

Description

technical field [0001] The present invention relates to a mortar composition, especially a leveling mortar composition and a component kit comprising the mortar composition and mineral wool, or an adhesive composition, or both. Another object of the invention is a structure, in particular a floor, wall or ceiling, comprising a substrate, a first layer, a second layer, optionally a third layer and optionally a covering element, in particular a patch ( tile). In addition, the present invention relates to the use of a mortar composition or a kit of components for fixing a patch to a substrate, acoustic damping, noise reduction and / or vibration damping. Background technique [0002] Substrates, such as ground substrates, are made of raw concrete, which is generally rough and uneven. This makes it difficult to fasten coverings such as tiles, carpets, vinyl floors, trim pieces, etc. in a satisfactory manner. Therefore, it is important to prepare a flat and smooth substrate surf...
