This invention discloses a composition and method of producing a hydraulic binder obtainable from municipal solid waste incineration bottom ash (MSWI BA). The technical problem and purpose of the present invention are to use as much of the MSWI BA as possible for the hydraulic binder for roads composition, at the same without compromising constructional characteristics of the hydraulic binder for roads. In the preparation method, the MSWI BA is maintained (aged) for at least 6 months. Then MSWI BA is dried, sieved, ground, and mixed with other dry components of the composition. The hydraulic binder for roads comprises 60-65% of MSWI BA, 30-40% of Cement CEM II A / LL 42.5 N, and 4-6% of Quicklime CL90. The mechanical and physical characteristics of hydraulic binder produced from this composition and by this method, complies with the requirements of the binder (strength class E2), according to EN 13282-1 or strength class N3, according to EN 13282-2 (Mix1). |
