IS 383 — Coarse and Fine Aggregate for Concrete – Specification

IS 383:2016 specifies the requirements for coarse and fine aggregates used in concrete for normal structural and mass concrete works. It covers natural aggregates like river sand and gravel, as well as manufactured aggregates including iron slag, steel slag, copper slag, recycled concrete aggregates, and bottom ash. The standard defines limits on deleterious materials, physical and chemical properties, grading, and testing methods to ensure aggregates contribute to durable, strong, and workable concrete. It is essential for engineers, concrete producers, and construction professionals involved in material selection and quality control of concrete aggregates in India.
