M400 Concrete (B30)
High-grade concrete for bridges, hydraulic structures and specially loaded elements
M400 (class B30) is a high-strength concrete intended for bridges, hydraulic structures, heavily loaded industrial structures and special engineering projects. Its 30 MPa strength and dense structure give it resistance both to load and to aggressive environments.
M400 has a high cement content and its mix requires stricter control — every batch is checked in our laboratory and passes the 28-day cube test. For infrastructure and industrial projects we organize scheduled supply.
Applications
Bridges and road structures
Load-bearing structures of infrastructure projects.
Hydraulic structures
A dense structure for elements in contact with water.
Industrial structures
Foundations for heavy equipment and industrial floors.
High-rise buildings
Heavily loaded structural elements of the lower floors.
Concrete grades we produce
All grades are produced to GOST 26633 requirements. See all grades →
Frequently Asked Questions
Where is M400 concrete used?
Bridges, hydraulic structures, heavily loaded industrial foundations, load-bearing elements of the lower floors of high-rise buildings and special engineering structures. For ordinary residential construction, M300–M350 is usually sufficient.
Why is M400 concrete more expensive?
M400 has one of the highest cement contents in the range, and production control is stricter. The exact price is calculated individually by volume and address — send a request and we will give you a comparative offer.
What is B30 concrete?
B30 is the strength class of the M400 grade: resistance to a pressure of 30 MPa. In projects, M400 and B30 refer to the same concrete.
Do I need M400 for a private house?
In most cases no — it would be an unnecessary expense. M400 is chosen when the design specifically requires it. If you are ordering without a design, tell us about the project and we will choose the right grade together.
