Ready-mixed concrete class B25 (M350)
M350 B25 concrete is the most durable and load-resistant type of building material. Its main area of use is industrial and commercial facilities. With its help, they are created: this type of mixture is already more often used in general and industrial construction than in civil. All subsequent grades are also used increasingly in the industrial sector.
