acceptable crushing strength limit for m grade concrete

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete''s relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...

Design of Reinforced Concrete Beams per ACI 318-02

For Grade 60 steel, this limit is set at 0.002. Sections are tension-controlled (ACI section 10.3.4) when the net tensile strain in the tension steel reaches a value of 0.005 or more just as the concrete in compression is equal to its strain limit of 0.003 (Fig. 6). In most cases, the 0.005 limit will provide ductile behavior for acceptable ...
