We produce crushed aggregate and quarry stone for all uses in construction. The individual aggregate are duly certified and regularly tested according to European aggregate standards and other technological standards according to the specific use.
Distribution of aggregate according to grain size, which is obtained by sieving through a system of sieves. The grain size indicates the range of mesh sizes of the lower and upper sieves in millimeters. The larger the number, the larger the aggregate. Ex .: PDK 4/8 - natural crushed aggregate with a grain size of 4-8 mm.
PDK: Natural crushed aggregate
PTK: Natural mined aggregates
MZK: mechanically reinforced aggregate
G-F: gravel with a mixture of fine-grained soil
GP: badly grained gravel
S-F: sand with a mixture of fine-grained soil
Loose aggregate - loose aggregate formed by the disruption (mining) of rock
