In the same way, 10 mm, 20 mm and 40 mm aggregates shall be combined in the ratio of 1:1.5:3 to get a 40 mm graded coarse aggregate. Fine aggregate of Zone II as per IS: 383-1970 is generally suitable for pumped concrete provided 15 to 30% sand should pass the 300 micron sieve and 5 to 10 percent should pass the 150 micron sieve.
· The Concrete mix design is as per Indian Standards (IS 10262) and might vary from country to country. The nominal mix design ratios available for concrete less than M30 in strength are only thumb rules and are generally over designed. As the actual site conditions vary and the mix design should be adjusted as per the location and other factors.
Experiment work consists for making of M30 grade concrete. The design of M30 is as per the IS code 1062: 2009 mix ratio obtained as 1:1.42:2.67:0.45 1.

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.
