Details specifications of Reinforcement Cement Concrete

In reinforcement cement concrete, steel is implanted in such a way in order that two materials function jointly in withstanding forces.

The reinforcing steel (rods, bars or mesh) engrosses the tensile, shear and often the compressive stresses in a concrete structure.

Specifications of RCC:

Shuttering should be provided with seasoned wooden boards having depth not under 30 mm.

Surface in contact with concrete does not contain any adhering grout, nails, splits and other flaws.

All the joints should be sealed properly and lined up.

The shuttering and framing should be adequately braced.

Presently, steel plates are used in place of timber shuttering.

All the props of sanctioned sizes are supported on double wedges and at the time of removing, these wedges are relieved and not knocked out.

All the formworks are detached once the 21 days curing period is completed devoid of any shocks or vibrations.

All the reinforcement bars are abided by IS specifications and do not contain rust, grease oil.

The steel grills should be placed properly according to detailed specifications.

The covers to concrete should be arranged properly according to related code.

Bars of diameter beyond 25 mm diameter should be twisted when red hot.

The ratios of materials should remain according to the specifications of the concrete.
