IS 456 (Indian Standard Code of Practice for Plain and Reinforced Concrete)

IS 456 is an Indian code that provides guidelines for designing and constructing safe, durable, and reliable plain and reinforced concrete structures like buildings and bridges. It sets standards for materials, proportions, structural design, and workmanship to ensure strength and safety. The code helps engineers and builders follow consistent practices, prevent failures, and achieve quality construction that lasts over time. Essentially, IS 456 acts as a comprehensive rulebook to ensure concrete structures are built correctly and safely.
