СПОСОБ ПЕРЕРАБОТКИ БЕТОННОГО ЛОМА (ВАРИАНТЫ)
FIELD: construction.SUBSTANCE: inventions relate to the field of construction and production of building materials and can be used in the manufacture of bricks, paving slabs and other small items, the installation of bases, including the foundations of roads. Method provides for crushing, moistening to normal molding moisture, mixing of the raw material containing hydrated calcium silicates and compaction at 20 MPa. Before compacting into raw material, which is used as a concrete scrap with water, add 10–40 wt. % wollastonite-containing rock containing 86 wt. % of wollastonite, ground to a dispersion of 2500–3000 cm/g, after which the resulting mixture is re-mixed. In another embodiment, before moistening, the crushed raw material, in the quality of which a concrete scrap is used, is further crushed from pieces 0.01–130.0 mm in size to pieces 0.01–5.0 mm in size, and compacting the homogeneous mixture obtained at 20 MPa or at 60–100 MPa.EFFECT: significantly increased strength of the resulting compact.2 cl, 3 tbl
