Coarse and Fine Aggregate for Concrete – Specification 2016 Edition
The 2016 edition of IS 383 outlines the criteria for both coarse and fine aggregates utilized in concrete for typical structural and mass concrete projects. It includes standards for natural materials such as river sand and gravel, as well as manufactured aggregates like iron, steel, and copper slags, recycled concrete aggregates, and bottom ash. The code sets limits on harmful substances, details physical and chemical characteristics, grading, and testing protocols to ensure aggregates enhance concrete durability, strength, and workability.
