What is IS 383 Code and Why is it Important for Concrete Construction?




Definition and scope of IS 383 code




IS 383 code is an Indian Standard that specifies the requirements for coarse and fine aggregates for concrete production. Aggregates are granular materials that are used as fillers in concrete mixtures. They can be derived from natural sources (such as sand, gravel, or crushed stone) or other than natural sources (such as iron slag, steel slag, copper slag, recycled concrete, or bottom ash).

IS 383 code classifies aggregates based on their sizes into fine aggregate (less than or equal to 4.75 mm) and coarse aggregate (more than or equal to 4.75 mm). Fine aggregate is further categorized into four grading zones (Zone I, Zone II, Zone III and Zone IV) based on their particle size distribution. Coarse aggregate is further categorized into two groups (Group I and Group II) based on their nominal size (10 mm, 12.5 mm, 16 mm, 20 mm, 25 mm, 40 mm, or 63 mm).


IS 383 code also specifies the requirements and specifications for aggregates such as grading, shape, strength, durability, moisture content, deleterious materials, and alkali-aggregate reactivity. These parameters affect the workability, strength, durability, and performance of concrete.


Importance and applications of IS 383 code




IS 383 code is important for concrete construction because it ensures the quality and durability of concrete structures. Aggregates constitute about 60-80% of the volume of concrete and have a significant influence on its properties. By using aggregates that conform to IS 383 code, you can achieve the following benefits:


  • Improve the workability and pumpability of concrete by using well-graded aggregates that reduce the voids and water demand in the concrete mix.



  • Enhance the strength and durability of concrete by using aggregates that have adequate strength, hardness, toughness, and resistance to weathering and chemical attack.



  • Reduce the shrinkage and cracking of concrete by using aggregates that have low thermal expansion and contraction.



  • Optimize the cost and sustainability of concrete by using aggregates that are locally available, economical, and environmentally friendly.



IS 383 code is applicable for all types of concrete construction such as buildings, bridges, dams, roads, pavements, tunnels, etc. It is also compatible with other Indian Standards related to concrete such as IS 456 (Plain and Reinforced Concrete), IS 10262 (Concrete Mix Proportioning), IS 516 (Methods of Tests for Strength of Concrete), etc.
