Reinforcements for concrete structures
In civil construction reinforcement is a backbone of any concrete structures and we often not familiar to follow accurate guidelines of use this costliest item for durable structures. Reinforcement steel named rebar enhanced concrete strength with its tensile strength characteristics. Due to similar coefficient of thermal expansion with concrete, rebar massively using in concrete structures. Type of reinforcements Mostly used rebars in construction are hot rolled deformed /TMT(thermo mechanically treated) bar with ribs. During manufacture no torsional force applied in TMT bars so that it can resist surface defect by cut bend better than cold rolled twisted rebars. Technical specifications for site use and follow up Deformed bar with grade 6o/grade 420 with carbon content 0.3% Cover of reinforcement clear cover 40mm,50mm,75mm. All spliced consider as tension zone UNO. As per ACI301,318 AND SP66 lap length to be generally between 34D to 48D Bar spliced such a way that ...
