Disadvantages Of Over Reinforced Concrete

reinforced cement concrete: types, advantages & disadvantages,disadvantages of reinforced cement concrete: the tensile strength of this concrete is 1/10 of its compressive strength. the price of this concrete used for casting is comparatively excessive. the rcc column section is larger than the metal section for multi-story construction. due to the shrinkage, the crack increases and the strength decreases..reinforcement in concrete topic,most concrete used for construction is a combination of concrete and reinforcement that is called reinforced concrete. reinforcement for concrete is provided by embedding deformed steel bars or welded wire fabric within freshly made concrete at the time of casting. the purpose of reinforcement is to provide additional strength for concrete where it is needed..

    Disadvantages Of Reinforced Concrete | Engineering Intro

    reinforced concrete can corrode easily because of the presence of steel. steel is heterogeneous material while concrete is a homogeneous material. therefore, if both materials will be used in combination than quality control will be very difficult. due to reinforcement, probability of cracking in concrete increases, because of shrinkage and creep in freshly lay concrete and hardened concrete.

    Balanced, Under-Reinforced And Over-Reinforced Beam Sections

    reinforced concrete beam sections in which the failure strain in concrete is reached earlier than the yield strain of steel is reached, are called over-reinforced beam sections. if over-reinforced beam is designed and loaded to full capacity then the steel in tension zone will not yield much before the concrete reaches its ultimate strain of 0.0035. this due to little yielding of steel the deflection and cracking of beam
