The "M" refers Mix and Number after M (M10, M20) Indicates the compressive strength of concrete after 28 days of curing and testing.. M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate.. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days.
Get PriceFor higher grade M30 and above we recommended a detailed concrete mix design. However as a guideline-a.The nominal mix proportion by Volume for M35 would be 1:1.35:2.7 The approximate quantities are Cement = 8.25 bags/cum of concrete Sand = 13.68 cft/cum Aggregate = 27.34 cft/cum. b. The nominal mix proportion by Volume for M45 would be 1:1.35:2.7

Get Price1-Nominal mix 2- Design mix Nominal mix- Nominal mix specifies the fix proportion of the cement, sand and aggregates. Ingredients of concrete are mixed on the basis of volume.It is a site level mixing of ingredients to prepare concrete mix.Such type of concrete mix is generally used in small quantity or where load is not high.
Get PriceThe 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 article we are going to discuss about the concrete mix design concept as per IS 10262-2009.
