What is IS 383 Code and Why is it Important for Civil Engineering?
IS 383 code is a standard that specifies the requirements for coarse and fine aggregates for concrete. Aggregates are inert materials that are mixed with cement and water to form concrete. They provide strength, stability, and volume to concrete. They also affect its workability, durability, and appearance.

IS 383 code covers aggregates from natural sources such as river sand, crushed stone, gravel, etc., as well as manufactured aggregates such as iron slag, steel slag, copper slag, recycled concrete, etc. It classifies aggregates into different types based on their size, shape, grading, source, etc. It also specifies the physical and chemical properties, quality control, sampling, testing, marking, packing, etc. of aggregates.
IS 383 code is important for civil engineering because it ensures that the aggregates used for concrete are suitable for their intended purpose. It helps to avoid problems such as poor strength, cracking, corrosion, alkali-aggregate reaction, etc. that may affect the performance and safety of concrete structures. It also helps to optimize the use of resources and reduce environmental impacts by promoting the use of alternative and recycled aggregates.
What are the Main Changes in the 2019 Revision of IS 383 Code?
IS 383 code was first published in 1970 and has been revised several times since then. The latest revision was done in August 2019 to incorporate the following main changes:
Incorporation of new types of aggregates from natural and manufactured sources such as bottom ash from thermal power plants, recycled concrete aggregate, recycled aggregates, etc.</li - Revision of grading zones and limits for fine aggregates to accommodate the variations in the availability and quality of natural sand across the country - Addition of new requirements for recycled aggregates and bottom ash such as minimum replacement ratio, maximum water absorption, maximum chloride content, etc. - Modification of some test methods and introduction of some new test methods for aggregates such as soundness test, alkali-silica reactivity test, etc. - Inclusion of some informative annexes on topics such as sampling and testing of aggregates, use of recycled aggregates, use of bottom ash, etc. These changes are aimed at improving the quality and consistency of aggregates for concrete, enhancing the sustainability and environmental friendliness of concrete production, and encouraging the use of innovative and alternative materials for concrete.

FAQs
What is the difference between coarse and fine aggregates?
Coarse aggregates are aggregates that have a nominal size greater than 4.75 mm. They are usually obtained from crushed rocks or gravel. Fine aggregates are aggregates that have a nominal size less than or equal to 4.75 mm. They are usually obtained from natural sand or crushed stone dust.
What are the advantages of using manufactured aggregates?
Manufactured aggregates are aggregates that are produced by artificial processes such as crushing, screening, washing, etc. They have some advantages over natural aggregates such as:
They can be tailored to meet specific requirements of strength, shape, size, grading, etc.
They can reduce the dependency on natural resources and minimize the environmental impacts of mining and quarrying.
They can utilize waste materials such as slag, fly ash, bottom ash, etc. and convert them into useful products.
How can I check the quality of aggregates for concrete?
You can check the quality of aggregates for concrete by performing some tests as per IS 383 code or other relevant standards. Some of the common tests are:
Sieve analysis: This test determines the particle size distribution and grading of aggregates.
Specific gravity and water absorption: This test determines the density and porosity of aggregates.
Crushing value and impact value: This test determines the resistance of aggregates to crushing and impact forces.
Abrasion value and flakiness index: This test determines the resistance of aggregates to wear and tear and shape characteristics.
Soundness test and alkali-silica reactivity test: This test determines the durability and compatibility of aggregates with cement.
What are the best practices for storing and handling aggregates?
Some of the best practices for storing and handling aggregates are:
Store aggregates in separate piles or bins according to their type, size, source, etc.
Avoid contamination of aggregates by dust, dirt, organic matter, etc.
Avoid segregation of aggregates by using proper methods of loading, unloading, transporting, etc.
Avoid moisture loss or gain of aggregates by using covers, shades, drains, etc.
Avoid damage or deterioration of aggregates by using suitable equipment, tools, containers, etc.
Where can I find more information and guidance on IS codes?
