Abstract: A kit of parts suitable to form a waterproofing membrane consisting of a first component A including or consisting of a) 5-60 mass parts, preferably 30-60 mass parts, more preferably 45-55 mass parts, of a hydraulic binder, b) 0.5-15 mass parts, preferably 1-5 mass parts of at least one synthetic polymer, c) 20-80 mass parts, preferably 30-50 mass parts of aggregates, and d) optionally further additives and a second component B including or consisting of an aqueous emulsion of bitumen.

Abstract: A mortar composition, in particular a leveling mortar composition, including: a) 3-45 wt. % of a hydraulic binder, b) 15-80 wt. % of lightweight aggregates, c) 5-50 wt. % of a polymer.

Abstract: A dry mortar, in particular a cementitious tile adhesive using fibers. A method improves the slip resistance, the flexibility, and/or the consistency of a dry mortar mixed up with water. Moreover, a structure, in particular a floor, a wall or a ceiling, includes a cover element, in particular a tile, whereby the cover element is fixed to the structure with a dry mortar mixed up with water.

Abstract: A process for the waterproofing of porous construction materials, the process including the steps of mixing water and a composition C, the composition C comprising, in each case based on the total weight of the composition C, a) 2-15 wt.-% of at least one binder selected from natural hydraulic lime (NHL), formulated lime (FL), and hydraulic lime (HL), b) 1-20 wt.-% of at least one pozzolanic material, c) 40-80 wt.-% of at least one aggregate, d) 2-30 wt.-% of at least one synthetic polymer, and wherein the content of Portland cement in said composition C is <3 wt.-%, applying the mixture thus obtained to a porous construction material, and optionally hardening the applied mixture.

Abstract: A mortar composition, in particular for preparing a viscoelastic structure and/or a fire barrier, including: a) 15-50 wt.-% of a hydraulic binder, b) 5-35 wt.-% of lightweight aggregates, c) 5-25 wt. % of further aggregates which have a particle density that is higher than the particle density of the lightweight aggregates, and d) 10-50 wt.-% of a polymer.

Abstract: A mortar composition, in particular a leveling mortar composition, including: 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.
