Choosing a grade
Frequently asked questions
What do the letters M and B mean?
M is the concrete strength grade (in kgf/cm²), B is the strength class (in MPa). For example, grade M300 corresponds to class B22.5 and has a strength of 22.5 MPa. Both figures are shown on every card. Note: as the GOST class row has no intermediate class, both M500 and M550 correspond to class B40.
Which grade should I choose for my project?
The grade depends on the structural load: M100–M150 for levelling and blinding, M200 for floor slabs and general work, M250 for strip foundations and load-bearing walls, M300 for monolithic foundations, slabs and columns, M350 and above for multi-storey frames, and the high-strength grades M500–M600 for industrial, infrastructure and special projects requiring high load-bearing capacity. If you are unsure, our specialists provide free advice.
How is concrete quality guaranteed?
All grades are produced under laboratory control in accordance with GOST 26633 and undergo 28-day strength testing.
