Annotation: This article examines the problem of using dune sands and waste in the production of nonmetallic industry for the production of concrete and reinforced concrete products. The use of sand dunes as a fine aggregate is most appropriate together with an enlarging additive, as which waste from the industry of non-metallic materials, in particular porphyritic rock, is recommended. The proposals of researchers on the use of fine sands in concrete and methods for selecting the composition of concrete are discussed. The share of deposits in Central Asia containing fine-grained and dune sand is indicated. The problematic nature of the use of building sand for use in the construction industry has been determined. The strength, deformability indicators, frost resistance, corrosion resistance of concrete based on the integrated use of sand dunes, crushing screenings and porphyry crushed stone were studied. The basics of the selection of sand dunes and porphyrite crushing screenings located on the territory of the Republic of Karakalpakstan for research purposes are given.
Keywords: porphyrites, dune sands, enlarger, size modulus, granulometry.
