    what is the mixture of M30 grade concrete

    • Er. Raj M. Khan July 10, 2012 at 6:49 am

      It is also in this website posted by me; just search

    • DEEPAK THAPA September 2, 2013 at 2:26 am

      As per our design is come M35 with ISCODE 10262-1982
      M35 ratio is come 1:1.2:2.2
      Water 20.5 lit/50Kg
      70%Aggraegate 20mm
      30%Aggregrate 10mm
      M30
      1:1.32:2.5
      Water 22.5 lit/50kg
      70%Aggraegate 20mm
      30%Aggregrate 10mm

    thank you very much sir,
    this is very useful to all who are working in this areas

  • Rajesh kumar March 19, 2012 at 7:34 am

    thank u for ur kind information ,keep in touch sir.

  • prasad ch April 6, 2012 at 6:43 am

    In M35 slump increase 75mm to 125mm already admixtures are used as for Mix design

    • Er. Raj M. Khan July 10, 2012 at 6:50 am

      Question not clear

  • nikhil ranjan pal from west-bengal, April 30, 2012 at 21:20 PM April 30, 2012 at 12:09 pm

    Dear Sir
    this is very useful to us who have engaged in bridge and other concrete work. what is the function of admixture to get target mean strength

    • Er. Raj M. Khan July 10, 2012 at 6:48 am

      Admixture does not play roll in increasing the strength however some PC admixture can be used to increase strength by 2 to 3 Mpa

  • vivek August 17, 2012 at 3:27 am

    please give me the mix design of m40 using 6mm metal

  • Er ubaidullah August 29, 2012 at 12:42 pm

    assalamu alaikum sir i hv seen ur method of solving mix design its fabulus sir jazaakalla hu khairrrr,,,,,,

  • jnm October 14, 2012 at 1:00 am

    the calculations are wrong. value of water content from table 2 is 186 litre (for 25-50mm slump). When the desirable slump is 50-75mm, water content should increase (& not decrease to 160 litre!)

  • Emdadul Haque November 27, 2012 at 8:12 am

    how to decide Percentage of 10mm and 20mm aggregate from total mass of aggregate?

  • LK Majhee December 6, 2012 at 8:30 am

    Can anyone please post the calculation of Mix Design M-55 (High slump and High Performance) using OPC 43/53 Grade and 10mm CA only. Use of Fly Ash is prohibited. Micro silica may be used.

  • B.B. Singh April 2, 2013 at 9:09 am

    Sir,
    What is the Admixture role We can design mix without it……..

    • g.rajasekar July 12, 2015 at 1:27 am

      The admixture role is increase the workability and decrease the w/c ratio at time strength will be incerased

  • DEEPAK THAPA August 28, 2013 at 3:03 am

    can any one provide me External footing design data

  • anil chauhan November 8, 2013 at 3:18 am

    dear sir

    please tell us about load capacity of M-35 Mix Design as per IS 10262-2009
    please tell us how much load it can bear

    • g.rajasekar July 12, 2015 at 1:30 am

      35 kn/m load will be bear

  • devi December 14, 2013 at 1:48 am

    Plain Cement Concrete 1:4:8 means What Garde

    • g.rajasekar July 12, 2015 at 1:33 am

      M10

  • mehboob shaikh July 12, 2015 at 12:43 am

    1:4:8 grade m5

  • Nalinda November 27, 2015 at 3:29 am

    what is the difference between grade 35 and grade 35A concrete ?

  • Pratap M. December 18, 2015 at 1:30 am

    Thank you Sir. I used to get confused when I discuss with local civil contractors since they are not aware of these calculations. They are used to talk in terms of volume ratios hence the calculations in A-8 column is very helpful.

    Thank you very much again.

  • ravi December 26, 2015 at 7:08 am

    which time admixture added in concrete

  • Arup May 9, 2016 at 2:30 am

    what is the mix ratio for M35, M40 grade?

  • sohail pathan December 15, 2016 at 12:24 am

    Sir,I have designed a mix for M35 using PPC and superplasticiser,Accelerated boiling water curing gave me result of 32 MPa but 7 days normal curing reading was 30 MPa which is Accelerated curing is good for PPC or not?? And I havent received workability inspite of adding admixture what should be done??
