# Concrete Mix Design M-60

CONCRETE MIX DESIGN (GRADE M60)

(a) DESIGN STIPULATION:-
Target strength = 60Mpa
Max size of aggregate used = 12.5 mm
Specific gravity of cement = 3.15
Specific gravity of fine aggregate (F.A) = 2.6
Specific gravity of Coarse aggregate (C.A) = 2.64
Dry Rodded Bulk Density of fine aggregate = 1726 Kg/m3
Dry Rodded Bulk Density of coarse aggregate = 1638 Kg/m3

Step-1
Calculation for weight of Coarse Aggregate:
From ACI 211.4R Table 4.3.3 Fractional volume of oven dry Rodded C.A for 12.5mm size aggregate is 0.68m3
Weight of C.A = 0.68*1638 = 1108.13 Kg/m3

Step-2
Calculation for Quantity of Water:
From ACI 211.4R Table 4.3.4
Assuming Slump as 50 to 75mm and for C.A size 12.5 mm the Mixing water = 148 ml
Void content of FA for this mixing water = 35%
Void content of FA (V)
V = {1-(Dry Rodded unit wt / specific gravity of FA*1000)}*100
= [1-(1726/2.6*1000)]*100
= 34.62%

Adjustment in mixing water = (V-35)* 4.55
= (34.62 – 35)*4.55
= -1.725 ml
Total water required = 148 + (-1.725) = 146.28 ml
Step-3
Calculation for weight of cement
From ACI 211.4R Table 4.3.5(b)
Take W / C ratio = 0.29
Weight of cement = 146.28 / 0.29 = 504.21 kg/m3

Step-4
Calculation for weight of Fine Aggregate:

Cement = 504.21 / 3.15*1000= 0.1616
Water = 146.28 / 1*1000= 0.1462
CA = 1108.13 / 3*1000= 0.3690
Entrapped Air = 2 / 100= 0.020
Total = 0.7376m3
Volume of Fine Aggregate= 1-0.7376
Weight of Fine Aggregate= 0.2624*2.6*1000= 683.24 kg/m3

Step-5
Super plasticizer:
For 0.8% = (0.8 / 100)*583.53 = 4.668 ml

Step-6
Correction for water:
Weight of water (For 0.8%) =146.28 – 4.668 =141.61 kg/m3

Requirement of materials per Cubic meter
Cement = 504.21 Kg/m3
Fine Aggregate = 683.24 Kg/m3
Coarse Aggregate = 1108.13 Kg/m3
Water = 141.61 Kg/ m3
Super plasticizers = 4.6681 / m3

So the final ratio becomes
Cement : Fine agg (kg/m3) : Coarse agg (kg/m3) : Water (l/m3): Superplasticizer (l/m3)

1: 1.35 :2.19 :0.29 :0.8

nice mix design

murthy says:

Dear Mr Nataraj nice Mix Design what is the workability of the mix.

Dear Mr Natrajan what is the workability of the mix.

chandan says:

we have this mix measured by liter box. farma

arun says:

thanks a lot…..sir can u plz send me design mix procedure of M80 grage concrete…. i m in an urgent need as m doing project on it….

T.C.V.Reddy says:

Dear Natarajan,

Thanks for this mix design, it is very useful.But we may not expect workability as the S.P is very low percentage

Anil kumar saini says:

sir! please forward me a copy or pdf file for estimation of civil drawing..& also

Solairaj.s says:

Its very use ful manuals to me. Thank you for this MIX design using the stds. I hope its increase as per site conditions.

Joyesh Manna says:

Excellent and useful. Many thanks to Mr Natarajan. Normally M60 grade concrete is done in specific, prestressed jobs.

arunkumar says:

mr Natraj,

iam very thankfull to you for doing this design mix.
our team will be following by your design.

thanks & regards

its very good mix design for out of india Engineers. i would like to see the mix design based on IS standards also if its possible.

thanks again

1)

need calculation of mix design with example for all use materials,if possible for
volumetric calculation,if any specific book required please send me name.

R.S.Saharia says:

It is suggested to use hyper plastisizer instead of superplastisizer. Also, T40 cement can give good results for high strength concrete.

Amal Bhattacharya says:

Conc mix design with cement content of 504 kg/cum. Is IS 456 2000 allows us more than 450kg/cum .
is it sustainable conc ?it is required to mention admixture and slump.require to revise

Dhanaraj lazarus says:

Your Posting is very usful i Need Design Mix of M40

Thanking You

mahendran says:

thank you natraj

Sunil Ramachandran Nair says:

Dear Mr. Natarajan,

I would like to know what is the admixture you had considered. In M60 mix design everything depends upon the admixture. I had used Glenium B233 from BASF if I remember correctly. Prior to that we used to import Microsilica.

Because of the inconsistency in the quality of present day cements, the role of admixture has become very vital. I hope you will agree with me. I had to use even for M40 grade of concrete such heavy admixtures which is economically very costly.

Just sharing some thoughts

Regards

Sunil R Nair
