The invention relates to mortar or concrete produced with a hydraulic binder, comprising aggregates from cinders from the bottom of municipal waste incinerators and/or from slurry from wastewater treatment plants, or other natural or artificial aggregates, of different particle sizes depending of the use thereof as mortar or concrete, and a binder consisting of: glass and/or other pozzolans; pure Portland clinker with gypsum or plaster of Paris, or the resulting cements following the grinding thereof; and/or optionally lime, depending on the quantity of glass and/or pozzolans; all of the materials forming the base of the binder being ground and mixed together until a binder is obtained, together with the aggregates, with cementing mineral neoformations and a strong pozzolanic character.

Disclosed are an organic binder-based coating; a composite gypsum board containing face and back cover sheets, an outside surface of the back cover sheet bearing the coating; and a method of preparing composite board where the back cover sheet contains the coating on its outer surface. The coating is formed from a composition comprising an alkaline silicate, a solid filler, and optionally, a borate. An enhancing layer can also be applied to the back cover sheet.

What is shown and described is a concrete element including a core concrete layer and a face concrete layer, the face concrete layer being obtained by compacting and hardening a mixture containing a latent hydraulic binder and/or a pozzolanic binder, water, a granular material and an alkaline hardener, with the granular material having, at a screen hole width of 2 mm, a through fraction from 35.5 wt. % to 99.5 wt. % and, at a screen hole width of 0.25 mm, a through fraction from 2.5 wt. % to 33.5 wt. %, each based on the total weight of the granular material.
