How RCC (Reinforced Cement Concrete) And RCC (Roller Compacted Concrete)

Reinforced concrete (RC) is defined as a compound material where comparatively low tensile strength and ductility of concrete are neutralized with the addition of reinforcement that contains greater tensile strength and/or ductility. The reinforcement generally includes steel reinforcing bars (rebar) and is typically implanted in the concrete prior to establishment of the concrete. Reinforcing schemes are usually planned to withstand tensile stresses in specific areas of the concrete that may lead unnecessary cracking and/or structural failure. Modern reinforced concrete consists of diverse reinforcing materials formed with steel, polymers or alternate composite material along with rebar or not. Reinforced concrete is also stressed (in compression) constantly, with the intention of enhancing the behavior of the final structure below working loads.
Various types of structures and components of structures like slabs, walls, beams, columns, foundations, frames etc. are developed with reinforced concrete.

Roller-compacted concrete (RCC) alias rolled concrete belongs to a special combination of concrete that contains basically the similar components as customary concrete but the proportion of components vary, and gradually with limited displacement of fly ash for Portland cement. RCC is combined with cement/fly ash, water, sand, aggregate and common additives, as well as much fewer water. The generated mixture is drying agent and basically contains no slump. RCC is arranged as same as the paving; the material is transmitted with dump trucks or conveyors, extent by small bulldozers or particularly reformed asphalt pavers, and then condensed by vibratory rollers.

Usually, RCC is utilized for backfill, sub-base and concrete pavement construction, but gradually it is applied to develop concrete gravity dams due to the low cement content and application of fly ash which produce a smaller amount of heat to be caused whereas curing performs customary mass concrete placements. Roller-compacted concrete proves to be cost-effective over customary mass concrete dams; these contain higher rates of concrete placement, lesser material costs and reduced costs involved with post-cooling and formwork.
