Concrete is made of cement, aggregates like sand and gravel, and water that provide density and strength when cured. Steel reinforcement is often added to concrete structures to increase their tensile strength and allow them to withstand greater stresses and make taller buildings possible. The two main concrete construction methods are sitecast, where concrete is poured on-site, and precast, where concrete elements are produced off-site - precast has advantages of speed and quality control but limits design flexibility.

concrete properties (density, workability, strength, etc.) What is concrete reinforcement?
What are the common types of reinforcing? Why steel is known as ideal material for
concrete reinforcing? Discuss the characteristics of concrete construction for very tall
buildings. In minimum of 300 words compare sitecast and precast concrete framing
systems. Specify the advantages and disadvantages of each method.#concrete
