Mix Design For M35 Grade Of Concrete

Posted in Mix Design | Email This Post Email This Post

The mix design for M35 Grade Of Concrete for pile foundations provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors.

Grade of Concrete : M35
Characteristic Strength (Fck) : 35 Mpa
Standard Deviation : 1.91 Mpa*
Target Mean Strength : T.M.S.= Fck +1.65 x S.D.
(from I.S 456-2000) = 35+ 1.65×1.91
= 38.15 Mpa

Test Data For Material:
Aggregate Type : Crushed
Specific Gravity
Cement : 3.15
Coarse Aggregate : 2.67
Fine Aggregate : 2.62

Water Absorption:
Coarse Aggregate : 0.5%
Fine Aggregate : 1.0 %

MIX DESIGN

Take Sand content as percentage of total aggregates = 36%

Select Water Cement Ratio = 0.43 for concrete grade M35

(From Fig 2. of I.S. 10262- 1982)

Select Water Content = 172 Kg

(From IS: 10262 for 20 mm nominal size of aggregates Maximum Water Content = 186 Kg/ M3 )

Hence, Cement Content= 172 / 0.43 = 400 Kg / M3

Formula for Mix Proportion of Fine and Coarse Aggregate:

1000(1-a0) = {(Cement Content / Sp. Gr. Of Cement) + Water Content +(Fa / Sp. Gr.* Pf )}

1000(1-a0) = {(Cement Content / Sp. Gr. Of Cement) + Water Content +Ca / Sp. Gr.* Pc )}

Where Ca = Coarse Aggregate Content

Fa = Fine Aggregate Content

Pf = Sand Content as percentage of total Aggregates

= 0.36

Pc = Coarse Aggregate Content as percentage of total Aggregates.

= 0.64

a0 = Percentage air content in concrete (As per IS :10262 for 20 mm nominal size of

aggregates air content is 2 %) = 0.02

Hence, 1000(1-0.02) = {(400 /3.15) + 172 +(Fa / 2.62 x 0.36)}

Fa = 642 Kg/ Cum

As the sand is of Zone II no adjustment is required for sand.

Sand Content = 642 Kg/ Cum

1000(1-0.02) = {(400 /3.15) + 172 +(Ca / 2.67 x 0.64)}

Hence, Ca = 1165 Kg/ Cum

From combined gradation of Coarse aggregates it has been found out that the proportion of 53:47 of 20 mm & 10 mm aggregates produces the best gradation as per IS: 383.

Hence, 20 mm Aggregates = 619 Kg

And 10 mm Aggregates = 546 Kg

To obtain slump in the range of 150-190 mm water reducing admixture brand SP430 from Fosroc with a dose of 0.3 % by weight of Cement shall be used.

Hence the Mix Proportion becomes:

We are thankful to Er. Ishan Kaushal for this valuable information.

    i tried a lot to do mix design my sllf but fail always pls send me the procedure to make design mix with example

  • gulshan June 15, 2010 at 3:19 am

    SIR,what is ehe criterea of taking the values of SD and ststastical factor.

  • C.M.Ray June 23, 2010 at 2:30 am

    Dear Sir,

    we are using zone iv sand in M-35 grade of concrete as Zone II & III sand is not available at this nearby localities. The suitibility of concrete mix proportion was achieved by satisfying the requirement with 40mm maximum nominal size aggregate in all in aggregate combination as stated in IS:383. The compressive strength is also found satisfactory at field.May we know any harmul affect to the structure in future.Plese comment.

  • K Wells July 26, 2010 at 1:32 am

    Can you please help me out with a 35mpa mix. I am mixing at 1.53 meter using
    1255kg washed sand
    1239 washed 3/8 rock
    252 Litres water = 43% W/C ratio
    580kg type 30 powder
    Air 650ML = 5-8% entrained
    Super Plasticizer 4743 ML
    We are trying to achieve a 8 3/4″ or 222 mm Slump. This is for precast. Is this a good mix or is there any recommendations?

  • Dillip Bera August 14, 2010 at 3:33 pm

    Sir, Can you please suggest me what is problem behind not to get required strength of M-35 grade concrete after 28 days, the ratio used 1:1.55:2.9 and w/c=0.45 and 0.75% water reducer by wt of cement, msa=20 mm down.
