Embodiment approach

[0031] According to an embodiment, a clinotlite CSA cement comprises clinker, the clinker comprising 37-47w% of clindenite, 20-35w% of calcium sulfoaluminate, 3-9w% of ferrite, especially C 4 AF, and 0.5-4.6w% CaO, each relative to the total weight of the clinker. The clinker used in the clinolite CSA cement of the present invention may contain other minor phases such as aluminates (CA, C 3 A, C 12 A 7 ) and / or ternesite (C 5 S 2 $).

[0032] In a particularly advantageous embodiment of the invention, the clinolite CSA cement additionally comprises at most 35w%, preferably at most 27w%, especially at most 15w%, of calcium sulfate, each based on the total dry weight of the cement . The calcium sulfate may be present in the form of calcium sulfate hemihydrate, calcium sulfate dihydrate and / or anhydrite. In a most preferred embodiment, CaSO 4 It exists as part of the clinker.

[0033] A clinomolite cement suitable in the context of the present invention is disclosed, fo...

Abstract

The present invention relates to a cement-based composition capable of realizing rapid formation of tensile adhesion strength. The composition comprises high-slope rankinite sulphoaluminate cement, and is applicable as, for example, a tile adhesive for rapid tiling and repairing. The invention further provides a rapid brick paving method.

Description

technical field [0001] The present invention relates to a cementitious composition with rapid development of tensile cohesive strength. The composition is suitable for use as an adhesive, especially as a brick adhesive for rapid tiling and repair. Furthermore, the invention relates to a structure, in particular a floor, a wall or a ceiling, comprising a covering element, in particular brick, wherein a cementitious composition is used to fix the covering element to said structure. [0002] Background of the invention [0003] Cement-based compositions such as cement-based brick adhesives or grouts can be differentiated as materials having rapid or regular hardening, eg tensile adhesion strength can be measured and differentiated as rapid or regular. The rapid development of tensile bond strength such as brick adhesives allows for a more rapid post-application to trafficable time. A faster time to passable is desirable as this results in faster builds and less downtime. [0...
