Mix Design For M35 Grade Of Concrete

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.

M 35 GRADE OF CONCRETE MIX DESIGNE WITH 43 GRADE OF CEMENT

yared terefe says:

Plesae send me mix design as per ACI code.Iam waiting for your reply

manoj patil says:

mix design with c/sand,n/sand all grade plz anybody reply me. or send my email

monish says:

how M45 grade concrete will be made with crusher sand

Hitesh das says:

what is the proportion of m55,m60,m65,….to m80

sachin says:

above M-20 you have to do mix design . then u can manipulate proportions

PKHAN says:

at the site how to measure proportion 1:2:4 or 1:1 1/2:3 all grade plz anybody reply me. or send my email

maha says:

1+2+4=7,cement density1440 so 1/7*1440=205.7 kg consider 1cum=1.57 so 205*1.57=322kg 6.5 bags,1bag cement .035cum ,6.5*.035=.22cum,sand 2time 2*.22 aggrete 4times 4*.22

bikas says:

I am executing a bridge With M35 Grade concrete . in DPR theoritical Consumption of Cement qty. shows .4738mt/cum, sand .5085cum/cum & coarse aggregate qty. 1.017cum/cum. But at site i am experiencing different thing. Can you suggest me about Theoretical Vs actual consumption .

madhanraj says:

what is the proportion of m55,m60,m65,….to m100. if it has more than 100 also send mix proportions for 150 too sir

Reply

madhanraj says:

by adding which material we can increase the strength of concrete

maha says:

hi,concrete purpose which gradation is required combined gradation(10mm,20mm only),or all in aggregate gradation (20,10,sand)

hitesh chauhan says:

mix design for m30 1:1:2grade we have black river sand and mix aggregate is only avalable so plz reply

dammy ladson says:

using:cement=380,fine aggregate=740,coarse aggregate=1111,water=185,sp-430=3.8 and fibre=4.4 all in kg/cubic metre,can i achieve grade 35

sujit says:

what is CRITERIA OF CONCRETE for M25

adekoya kayode says:

what are the criteria for m20,m25 grade of concrete?

Mohammed Huzaifa says:

I m very thank full to civil engineering portal, this web site to share information a

bout civil engineering with us. I hope i will received tips about civil engineering from u.
Thank you.

M.Vikneswaran says:

Very good information sharing website. Please update me on the information of Civil Engineering. Thank you.

Abhi2Yogi says:

Respected sir / madam can anyone pls tell me what are the standard mix ( proportion ) for the standard mix of concrete.:-):-):-)

satya krishna says:

send me the mixed proportions as foundations in sea

breddyravinderreddy says:

as per :10262 all mix designs can be calculated,but up to M25 proportions are constant why?

DEEPAK CHAUHAN says:

D/Sir,
I am very pleased with the information.If possible Please post M 35 Mix Design using PSC Cement(Ultratech)
