Reinforced concrete RC also called reinforced cement concrete or RCC is a composite material in which concrete s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility The reinforcement is usually though not necessarily steel reinforcing bars and is usually embedded passively in the concrete before the NPK s Primary/Secondary Concrete Crushers are designed to effectively handle any primary and/or secondary demolition and recycling operation NPK concrete pulverizers easily crush through reinforced concrete and cut through light steel structures allowing material to be separated and recycled and simultaneously permits easier handling of material

The reinforced concrete material model is treated as statistically homogeneous with different tensile and compressive behaviors It follows a “smeared” crack model where cracking and crushing are simulated via degeneration of the elasticity at integration points instead of tracking individual macroscopic cracksFailure analysis of reinforced concrete was a leading subject for research in the late 80’s and 90’s in Europe the US and Japan Mathematical formulations for cracking and crushing of concrete were developed and validated in experimental tests

Reinforced cement concrete Since concrete is a brittle material and is strong in compression It is weak in tension so steel is used inside concrete for strengthening and reinforcing the tensile strength of concrete The steel must have appropriate deformations to Nov 14 32 The SP30 is designed to be a reliable and powerful tool for secondary demolition and recycling of concrete It powerfully crushes reinforced concrete with its wider jaw exceptional closing force and short cycle times provides excellent productivity in concrete reduction and reinforced steel separation claims the company

For over reinforced beams concrete crushing is the primary contribution to the failure of the beams Nanni and Tanigaki Such a compression controlled failure mode may be recommended for the design of FRP prestressed concrete beams considering safety issues Lees Grace and Because FRP rebars do not yield like steel bars FRP reinforced members are generally over reinforced that is the ratio of FRP reinforcement to concrete is greater than the balanced ratio so that concrete crushing of the member controls the failure mode
