The largest faction. It is used in the manufacture of concrete, in foundations, when pouring bridges, roads, etc. Its properties make it an excellent building material. This is the best material for a nap.
Natural crushed stone fractions of 40-70 mm are large cuboid rock fragments formed as a result of crushing, repeated washing, and dispersion on a technological production line.

Main Features

The properties that favorably distinguish our granite rubble 40-70 mm from analogues include:

• Low greediness and purity. It contains a minimum of needle-like and lamellar grains, clay inclusions, and harmful impurities.;

• Strength of at least 1000 MPa. It can withstand prolonged static loads, practically does not sag or collapse when exposed to waves, pressure from heavy machinery and massive structures.;

• Frost resistance F300. Retains properties after 300 cycles of freezing/thawing;

• High adhesion. Due to the rough surface, it forms strong bonds with cement mortars.

The large crushed stone sold by our company has a normal radioactive background, which makes it suitable for the construction of residential and social infrastructure facilities.

Areas of application

Crushed stone 40-70 mm is used in:

• forming cushions for motorways, tramways and railway tracks;

• construction of embankments, dams;

• creating foundations for high-rise buildings and bridges;

• manufacture of dimensional precast concrete;

• filling wells, pits and trenches;

• Organization of groundwater drainage systems;

• construction of gabions, alpine slides, flower beds.

We do not involve intermediaries in the production and transportation of crushed stone 40-70 mm, which allows us to maintain a low price per ton, guarantee the weight and quality of each batch.
