Strzegom granite

Granite from the area of ​​the Strzegomskie Hill is an exceptionally hard rock, resistant to harsh weather conditions and damage. Its characteristic and natural beautiful appearance is the result of stone minerals, which most often include quartz, bright plagioclase and black biotite. In addition to its aesthetic qualities, the Strzegom granite is distinguished by exceptional durability, which is why it is so eagerly used in construction. It is used to build roads, parking lots, terraces and stairs.

The Strzegom granite has excellent technical parameters. The density is 2.65 g / cm3. In addition, the granite from Strzegom is resistant to compression (strength 132.1 MPa) and abrasion (abrasion on the Boehme disc 3.17 cm, abrasion in the Deval drum 6.2%). It is also distinguished by low water absorption (0.36%) and total frost resistance.
