5000 psi concrete crushing test yields what mpa in belarus

No single strength test should fall below ƒ´cby more than 500 psi 345 MPa or by more than 010 ƒ´c when ƒ´c is more than 5000 psi 35 MPa It is important to understand that an individual test falling below ƒ´c does not necessarily constitute a failure to meet specification requirements... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
