Abstract: A process for producing Portland cement clinker at low temperatures fixing the sulfur produced by burning high sulfur content coke fuel. The invention also describes a Portland cement clinker that includes new additional phases.

Abstract: A waterproof cements mortar or concrete compound is described. The waterproof compound contains a synergically effective quantity of a composition of water repelling and water reducing agents that are added to the waterproof compound as it is manufactured. Also described are synergic compositions for waterproofing and manufacturing methods for producing said waterproof compounds.

Abstract: A concrete-based floor or coating with anti-microbial effect, comprising a base material and an effective amount of at least one microbicide organic agent, mixed directly with the base material is described; the base material is a mixture containing cement, fine aggregates, solid aggregates, additives and water; where the microbicide agent mixed with the base material provides an efficient and long lasting anti-microbial effect.

Abstract: This describes a method for producing cement clinker using petroleum coke with a sulfur content over 4.5% by weight, in conventional equipment and facilities, wherein said method comprises the treatment of the raw mixture to synergistically improve its physical-chemical characteristics combined with the parameter control of the process, in such a way as to obtain a reduction of the clinkering temperature, all as a heretofore-unappreciated way to reduce, as a result, the concentration of SO3 in the calcinated material fed to the rotating kiln, and also usefully increasing with this the calcium sulfate content in the clinker.
