  • Types of Ready-mixed Concrete | Hanson UK

    RC is used for a series of designated concretes that are used in concrete that will be reinforced, pre-stressed or containing embedded steel. The specifications for the RC-series of designated concretes include requirements for maximum w/c ratio (W/C) and minimum cementitious content (MCC), which makes specification easier and complete. The range of uses for this group of mix types ranges in
