The ways to increase the durability of cutting tools (sintered carbide knives) in the production of steel fiber
One of the ways to increase the strength and reliability of building structures is the use of steel – fibre reinforced concrete. Steel – fibre reinforced concrete has significant advantages over conventional concrete. A high degree of resistance to cracking contributes to an increase in such physica...
