Thumb rules for Structural Design | RCC Structures Design of RCC Structural- camelwayponents. In this article, we are going to discuss the minimum standards that are to be followed for the design of Structural- camelwayponents of a building such as Columns, beams, slab and foundation.

Concrete is a- camelwayposite material- camelwayposed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as calcium aluminate cements.

What is concrete mix design and proportions? Concrete mix design may be defined as the art of selecting suitable ingredients of concrete and determining their relative proportions with the object of producing concrete of certain minimum strength & durability as economically as possible.

Introduction Concrete is, by nature, a brittle material that performs well in- camelwaypression, but is considerably less effective when in tension.. Reinforcement in concrete is used to absorb these tensile forces so that the cracking which is inevitable in all high-strength concretes does not weaken the structure.

(1 cement – 6 aggregate, by weight, 0.60 water – cement ratio). In some literature the required grade of concrete is noted by the proportions of cement – sand – stone, so called nominal mixes rather than the- camelwaypressive strength.
