Quarry crushed stone 20-40 mm

Slightly larger in size than its predecessor. It is used in the manufacture of concrete, in foundations, when pouring bridges, roads, etc. Its properties make it an excellent building material. It is the best filler for concrete and creating a "cushion" during roadway construction.

Radiation quality AeFF Bk./ct. - 42 Crushed stone 20x40 mm is a popular loose building material of non–metallic origin, obtained by crushing, repeated washing, and scattering of rocks, taking into account the requirements of GOST 8267-93. It has a cuboid shape, a porous structure, and a rough surface, which creates strong bonds with the cement-sand mixture and forms a solid, monolithic, and relatively smooth surface when rolling or tamping. Advantages of our crushed stone Thanks to our 4 own quarries and a technological processing line, we supply crushed stone with a fraction of 20-40 mm with: • strength of at least 1000 MPa; • frost resistance of more than 300 cycles; • minimum amount of bream particles, clay and harmful impurities. We produce 20-40 mm crushed stone from GHGS with a normal radioactive background, which allows it to be used in the construction of facilities that have special environmental requirements. Field of application Natural crushed stone of 20-40 mm fraction is in demand for: • creating the foundation for multi-storey buildings, railway tracks, highways; • production of reinforced concrete blocks with increased strength; • arranging pillows for foundations; • organization of embankments, platforms for special equipment; • pouring road slabs, wall blocks, monolithic structures; • formation of drainage layers; • filling of rough roads with low-intensity traffic.
