摘要

The invention relates to the use of desert sand as an aggregate for concrete, a method for producing an aggregate for concrete and an aggregate for concrete. According to the invention, the desert sand has been crushed beforehand by pressing in a first step a bed of desert sand between the grinding rollers of a high-pressure roller press having at least 50 MPa, which is sufficient for crushing and agglomerating the fragments, and in a second stage the agglomerates Another mechanical stress is destroyed. Aggregate produced in this way, when added to concrete, leads to a considerably higher concrete strength than when adding untreated desert sand.
