Reinforced concrete - Wikipedia

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

Construction Techniques for Roller-Compacted Concrete

aggregates in RCC are not as strict as those for aggregates used in conventional concrete. Because heavy rollers, common to earth or rock construction, are utilized to densify RCC, aggregate gradation is not as important to achieving desired density as is slumpable concrete production (11). If mass, not strength, is the controlling characteristic, then a wide gradation range for aggregate

HOW TO DECIDE MAXIMUM SIZE OF COARSE

On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved. In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate upto 20 mm may be used. Conditions That Decide Maximum Size of Coarse Aggregate to be Used in
