Specification for Coarse and Fine Aggregates From Natural Sources For Concrete

IS 383 (1970) specifies the requirements for coarse and fine aggregates obtained from natural sources for use in concrete. It defines quality parameters such as grading, particle shape, deleterious materials limits, mechanical properties, and soundness to ensure aggregates contribute to durable and strong concrete. This standard is essential for engineers, contractors, and suppliers involved in concrete mix design and construction to select and verify aggregates that meet performance and durability criteria.
