The invention provides composite materials comprising novel bonding elements exhibiting unique microstructures and chemical compositions, and methods for their manufacture and uses, for example, in a variety of concrete components with or without aggregates in the infrastructure, construction, pavement and landscaping industries.

Composite materials and bonding elements from carbonation of calcium silicate and methods thereof

The invention provides novel, microstructured clinker and cement materials that are characterized by superior grindability and reactivity. The disclosed clinker and cement materials are based on carbonatable calcium silicate and can be made from widely available, low cost raw materials via a process suitable for large-scale production. The method of the invention is flexible in equipment and processing requirements and is readily adaptable to manufacturing facilities of conventional Portland cement.

Microstructured carbonatable calcium silicate clinkers and methods thereof

A method for treating polluted soils, includes mixing the soil with a hydraulic binder, wherein the hydraulic binder includes: as the only high-alumina clinker, a high-alumina clinker including more than 80 wt % of mayenite C12A7 phase or a mayenite isotope, the high-alumina clinker making up at least 70 wt % of the weight of the hydraulic binder; and 1 wt % to 30 wt %, relative to the total weight of the binder, of lime.

Method for treating polluted soil by a hydraulic binder with mayenite phase

The present invention relates to a process for the production of a clinker with a high content of belite, said process comprising the following steps:

Industrial process for the production of a clinker with a high content of belite

A mix including at least one hydraulic and/or pozzolanic material and at least one water-soluble cationic polymer, the cationic polymer having a density of cationic charges greater than 0.5 meq/g and an intrinsic viscosity less than 1 dl/g, and the hydraulic and/or pozzolanic material not being clinker, nor limestone, nor gypsum, nor calcium sulphate, nor anhydrous calcium sulphate, nor hemi hydrated calcium sulphate, nor plaster, nor lime.

Composition with a base of hydraulic and/or pozzolanic material

The present invention relates to a composition including at least a Portland clinker and a Belite-Calcium-Sulphoaluminate-Ferrite clinker (BCSAF).

Hydraulic binder with a base of sulfoaluminate clinker and portland clinker
