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

    Bug holes and pin holes can be eliminated by using Hypercrete , SCC admixture @1000ml/100kg of cement. You can go to very law w/c ratio like 0.2 and achieve very high strength with comparably very law cement content while having self compacting properties. Hypercrete can be used in high dosage for G70 or G80 concrete. Sometime you may have to blend the concrete mix with 10 -15% silica fume.

    Dear All
    Although IS 456 limits the use of cement / cu.m to 450 kgs, it can be increased upto 540 kgs as per MORTH standard. However difficulties encountered during hot climate has to be taken into account to avoid thermal cracks. Also please note the proportions obtained on calculations from IS 10262 are only a guidance, however trial mixes have to be done to observe the properties of fresh concrete viz., cohesiveness (for enhance pumpability), workability etc. CA & FA proportions may be changed purely on All – in -aggregate curves. For high strength concrete it is normal practice to add MICROSILICA @ 5 – 8 % of cement content to achieve desired strength.

    • revanasiddesh April 3, 2012 at 6:57 am

      Sir please send me that morth specification so that cement content can be taken up to 540 kg/m3 and how to avoid the thermal cracks during hot climatic condition. and instead of using 12.5mm aggregates if we use 20mm, water content increases and hence the cement content. so please send me how to overcome this problem.

    What is PT Concrete Grade & what is mix design for M35PT concrete.

  • mohammed naeem ansari November 17, 2011 at 4:30 am

    how limit in m-60 concrete, water/cement ratio
    which In IS Code For water/cement Ratio

    Sir Is Very Urgent
    Please Help Me

    • sujit May 10, 2012 at 7:09 am

      Is 456 is no confirms limit, it is base of referance book, if you make M60 Grade then you W/c ratio is almost 0.28 to 0.30 & Admixture is BASF Glenium B276 & Sika then you get M60 Grade
