INTEGRATED PROCESS FOR MANUFATURING HYDRAULICALLY HARDENING BUILDING MATERIAL
Method for manufacturing hydraulically hardening building materials, comprising:- providing concrete demolition waste with a maximum particle size of up to 150 mm as a starting material,- mixing the starting material with water to form a feedstock slurry,- introducing carbon dioxide or a precursor thereof into the feedstock slurry to form carbonated concrete fines in an amount from 1 to 100 wt.-% of the hardened binder contained in the starting material and to detach the concrete fines from the aggregate contained in the starting material to form a product slurry, and- mixing the product slurry with a cement forming the building material,and use of the obtainable building material for manufacturing building structures as well as method for manufacturing a supplementary cementitious material slurry comprising the steps:- providing concrete demolition waste with a maximum particle size of up to 150 mm as starting material,- mixing the starting material with water to form a feedstock slurry,- introducing carbon dioxide or a precursor thereof into the feedstock slurry transforming from 1 to 100 wt.-% of the hardened binder contained in the starting material to carbonated concrete fines with a reactivity index of at least 1.1 times to form the supplementary cementitious material slurry.
