CO2-CAPTURING BINDER, PRODUCTION METHOD THEREOF BASED ON THE SELECTION, PURIFICATION AND OPTIMISATION OF CARBIDE LIME, AND AGGLOMERATES HAVING AN ENVIRONMENTAL ACTIVITY.

摘要

The invention relates to: a CO2-capturing binder having an amortised environmental cost; the production method thereof, which is based on the selection, purification and optimisation of carbide lime paste for use as a binding material; and agglomerates for the production of lime paints and washes, stuccos, mortars and concretes having multiple uses in the construction industry, in architectural restoration, in public works and soil conditioning. The invention is essentially characterised in that the raw material is residue in the form of sludge generated during the industrial production of acetylene (C2H2) from calcium carbide (CaC2), the basic component of which is calcium hydroxide (Ca(OH)2) in highly reactive nanometric formations, which undergoes a specific treatment in accordance with the invention.
