    what is the mix ratio of M25 Grade of concrete?

  • Ankit Shrivastava August 31, 2013 at 4:59 am

    Thankyou for explaining us But I have a doubt that at some places people are using 1:1:2 ratio (nomnal mix) for finding cement, fine and coarse aggregate. Can you tell me which one is correct or which method should be used and when

  • Abdelrahim September 17, 2013 at 2:46 pm

    Thank you for the information .. I would like to know the same m25 for natural coarse aggregates ?

  • kumar kamble March 22, 2014 at 11:42 am

    Can u explain me i want to quantity material for m20,m25

  • Dharm Pal Raseela March 23, 2014 at 10:41 am

    Sir, if OPC cement is not available than can we use any PPC cement for mix design M-25 for testing
