Sand-gravel mixture in Ulan-Ude

Granite crushed stone of the 70-120 mm fraction is a crushed igneous rock obtained as a result of magma crystallization. This material is characterized by high strength and excellent technical characteristics, which makes it ideal for use in the production of concrete mortars and in construction. Crushed stone of this fraction complies with the GOST 8267-93 standard and is shipped from the MBZ transshipment base with the necessary documents, including waybills and a quality certificate.

The base always has crushed stone of the highest, first and second class. The classification of the material is based on strength, radiation background and the percentage of small fractions: the highest class is the purest and most durable, class 1 is with small impurities (up to 5%), class 2 is with impurities up to 10%. MBZ stores more than 3,000 m3 of non-metallic materials, which ensures the constant availability of various fractions of crushed stone. The bulk density of crushed stone of the 70-120 mm fraction is 1,400 t/m3. ...
