Abstract: The invention relates to a binder composition for the cold forming of metal ore pellets, wherein the binder composition comprises a hydraulic binder component and additives, wherein the hydraulic binder component has a fineness of at least D95<40 ?m, D50<12 ?m, D10<5 ?m (determined by laser diffraction particle size analyzer) with a Blaine fineness between 6500 and 9000 cm2/g wherein the CaO content is >62.5 wt.-% and the content of C3S is >60 wt.-%, preferably >65 wt.-%.

Abstract: A method for the construction of a data center, includes (a) providing a fresh concrete composition including a paste that includes a hydraulic binder, a mineral addition and water, the paste being present in a mixture with sand and aggregates, whereby the paste is present in the concrete composition in a volume of <320 L/m3 and/or the solid volume fraction of said paste is >50 vol.-% and (b) placing the fresh concrete composition so as to build walls, a floor and/or a ceiling of the data center, which are intended to surround the individual components of computer systems, which are housed in the data center.

Abstract: A process of preparing a cemented paste backfill material, the material including ground mine tailings, a hydraulic binder and water, wherein the solids content of the backfill material is 70-82 wt.-%, the process including a) providing a dry premix, the premix including the hydraulic binder, a superplasticizer and optionally a defoaming agent, b) mixing the dry premix with the ground mine tailings and water.
