Sand-gravel mixture in Salekhard

A sand-gravel mixture (with a gravel content of up to 10%) is a natural non–metallic building material that is not regulated by Standards and GOST standards, consisting of sand with a gravel content of up to 10% by weight. This type of product is produced by hydro in a mechanized manner using a C-42 type dredger by extracting the top layer of a sand-gravel mixture with a low gravel content, as well as washing this mixture with a large amount of water to remove pulverized and clay particles. As a result of production and technological processes, this non-metallic building material has the following physical and mechanical properties:

1. Bulk density, equal to 1480 kg/m3; ...

A sand-gravel mixture (with a gravel content of 30-50%) is a natural non–metallic building material regulated by GOST 23735-2014, consisting of sand with a gravel content of 30% to 50% by weight. This type of product is produced by a hydromechanized method using a C-42 type dredger by extracting the raw materials of a gravel-sand mixture with a high gravel content in the sole of the bottom layer, as well as washing this mixture with a large amount of water to remove pulverized and clay particles. As a result of production and technological processes, this non-metallic building material has the following physical and mechanical properties:

1. Bulk density, equal to 1500 kg/m3; ...
