    thanks for your guidance about mix design sir…….

  • Tony February 22, 2012 at 5:03 am

    Dear sir,
    If i use the specific gravity -dry, for the calculations of mix design, is there any problem for the presentation?

    • Er. Raj M. Khan July 10, 2012 at 6:57 am

      No, You can not use the dry specific Gravity, because you have to maintain W/C ratio & After that the moisture correction is to be made. else the desired slump can not be achieved.

  • HEMRAJ May 11, 2012 at 1:30 pm

    which admixture will used in M30 grade concrete ,give ex.

  • surya June 13, 2012 at 11:44 am

    please give description about unit weight of m30

    • Er. Raj M. Khan July 10, 2012 at 6:58 am

      just add the concrete ingredients of m-30

    • sauvir singh November 24, 2012 at 7:32 am

      water =173.23 kg cement= 455.87kg fine aggregate (specific gravity2.67 =442.27 kg
      coarsse aggregate specific gravity (2.92) = 1405.69 kg

      unit wt of m30 after 28days curing is = 2650kg /cum in lab condition it may be deffer at site

  • Oryakhel June 13, 2012 at 2:46 pm

    thanks for every one helping each other

    • Er. Raj M. Khan July 10, 2012 at 6:58 am

      its my pleasure

    Very thankful to you sir

  • dilip swami October 7, 2012 at 7:20 am

    sir for making m-30 or m40 class paver which machine i purchase technically.thanks

  • kalyan kumar giri October 13, 2012 at 9:23 am

    dear, sir can u write me what are the ratio i used (cement, sand, stone dust,water or any chemical for making of solid bricks) which is harden and can be used for construction of building. i newly start production of cement solid brick for rural people which is cheaper then clay brick thankin you

  • Anil gupta October 29, 2012 at 6:13 am

    Can you plz help me with m30 mix ratio in kg.it would be very helpful of you. Ithank you

    Dear sir,
    If i use the specific gravity -dry, for the calculations of mix design, is there any problem for the presentation?

  • tarun jain February 6, 2013 at 8:35 am

    for the example that you have solved for m30 what’s the mix ratio sir

  • sivakumar February 12, 2013 at 1:27 am

    what is mix ratio for m30

  • tarun jain February 20, 2013 at 7:08 am

    am gettin 41.5 as strength at th7 day for m30 amd opc 53. is it correct

  • krutik tachak March 5, 2013 at 9:25 am

    can anyone tel me mix proportion for M30 in terms of ghamela ??? like at site i used normal concrete mixer . so wat do i need to tell to labour to pour in the materials

  • ER. SUSANTA KUMAR MISRA April 12, 2013 at 5:52 am

    This is very necessary for all civil engineers. Thanks to all.
    How can we calculate the Mix design for M-30 C.C keeping cement content constant ?

  • NIRVESH JAISWAL July 3, 2013 at 7:17 am

    can design mix concrete be converted into nominal mix concrete at work site for concrete grade more than M25 and above.

  • Dr.A.R.Majumdar July 23, 2013 at 10:49 am

    can i suggest some clarity and improvement?

  • Goutam kumar dutta July 30, 2013 at 1:15 am

    Dear sir can U write me the mixer machine mix m-30 site. pl. write me Box size. Thanking you

  • prakash gavhane October 2, 2013 at 12:04 am

    what is the ratio of concrete above m35,40,45& above?
