VERWENDUNG VON BEHANDELTEM WÜSTENSAND ALS ZUSCHLAGSTOFF FÜR BETON
Desert sand is treated to be used as an aggregate for concrete, a method for producing an aggregate for concrete is provided, and to an aggregate for concrete is provided. The aggregate is obtained by crushing desert sand in a high-pressure roller press, wherein, in a first stage, the desert sand in a bed is crushed by pressure exposure, and then forms agglomerates. In a second stage, the agglomerates are disrupted by further mechanical exposure. The pressure exposure in the first stage is accomplished by a single pressing between two surfaces at more than 50 MPa pressure. Aggregate produced in this way results in substantially greater concrete strength than when untreated desert sand is added.
