Extra-firm concrete – the newest material in a list of modified concretes, made by our company. High figures of physical and mechanical properties, proved by the investigations, allow us to use this extra-firm concrete for making pavement blocks, paver, façade stones, fences, borders, and make all this production extremely qualitative and beautiful.

Here are some results of physical and mechanical investigations of extra-firm concrete products:

Compressive strength 700 кг/см2
calculated tensile strength 70 кг/см2
frost-resistance no less then 700 cycles (F700)
water absorption 0.3%
abradability 0,2 g/sm2
