The products manufactured by the Flashstone technology have high wearproof characteristics:
1. Compressing strength from 600 to 1000 kg/cm 2
2.Tensile strength at bend from 60 to 150 kg/cm 2
3. Frost resistance not less than 500 cycles (F500)
(freezing at -20o C and defrosting at +20o C)
4. Water absorbing characteristic less than 3%
5. Wearability (abrasive resistance) less than 0,4 g/cm 2
Increase of concrete strength in Flashstone products hardening at temperature of +20Co
