# Concrete Mix Design M-60

(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

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

satpal.singh says:

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

SANJAY SONI says:

which super plastisizer should be use to make M70 GRADE OF CONCRETE

satish says:

Glenium can be suitable

prakash kotwal says:

sir, for achieving compressive strength about 75 mpa after 7 day by using m53 grade cement ,what procedure have to use . please send the design on my email. plzz

Dear Sir,
I would like know about the what is different between 43 & 53 grade cement.

AWAIS says:

dear sir,
i want to asked about the cement factor what is the main role of it in concrete mix design.

Rahul Raghav says:

Sir,
How was control the quality give me suggeation & how was make self compaction concrerte.

Bharat says:

Sir want Mix Design of M50 and M60 Grade which can be made at our site with 10mm metal for 1 bag Cement as have Jacket the Building’s Retaining wall and pardi by 75 to 100mm.

Ganesh Patankar says:

Dear Sir,

i want information related to SCC Vs Normal concrete,code applicable to SCC

Anand S. Agrawal says:

Dear Sir,
If Coarse aggregate fail to confirm gradation requrement of nominal size 20mm,10mm as per IS 383. (For eg. 75% passing 20mm sieve, required Min. 85% passing)Can we further proceed for mix design. As basic requirement of Mix design as per IS: 10262:2009 is aggregate conforms to IS:383.
