Procedure for concrete mix design calculation as per IS 10262-2009 based on strength and durability, workability, economy is discussed in this work. To produce concrete of required strength and properties, selection of ingredients and their quantity is to be found which is called concrete mix design. Proper mix design will solve every problem which arises in concrete while placing or curing etc.. The mix design also helps to produce economical concrete. Generally, cement is more costly than other ingredients of concrete. So, quantity and quality of cement is designed by proper mix design concept. In this work we discuss the concrete mix design concept as per IS 10262-2009.
