### 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/m^{3}

Dry Rodded Bulk Density of coarse aggregate = 1638 Kg/m^{3}

**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 0.68m^{3}

Weight of C.A = 0.68*1638 = 1108.13 Kg/m^{3}

**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/m^{3}

**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 = 0.7376m^{3}

Volume of Fine Aggregate= 1-0.7376

Weight of Fine Aggregate= 0.2624*2.6*1000= 683.24 kg/m^{3}

**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/m^{3}

**Requirement of materials per Cubic meter**

Cement = 504.21 Kg/m^{3}

Fine Aggregate = 683.24 Kg/m^{3}

Coarse Aggregate = 1108.13 Kg/m^{3}

Water = 141.61 Kg/ m^{3}

Super plasticizers = 4.6681 / m^{3}

So the final ratio becomes

Cement : Fine agg (kg/m^{3}) : Coarse agg (kg/m^{3}) : Water (l/m^{3}): Superplasticizer (l/m^{3})

**1: 1.35 :2.19 :0.29 :0.8**

this is very usefull to civil engineers

sir,pls send me the mix design for m60 and m40 concrete. i am doing a project.sir pls kindly send.

sir i need the standard deviation value for m60 concrete

Sir,I am doing research work in self curing concrete.i found difficulties in setting of objectives.i have tried poly vinyl alcohol as self curing agent . i am unable to get research papers in this area so pl. guide me.

dear sir

i am going to establish a afly ash brick plant kindly let me know what is the mix proportion for 7.5 grade brick

Dear sir,

I wanna know how we can specify moisture correction on water content with respect to the nature of the surface of the aggregates in BIS method

I am already manufacturing concrete tiles and paver block in vibro table kindly suggest me the the mix design for M-40 and M-30.

which specific gravity select for mix design bulk or apprant

Specific Gravity (OD) oven dry state is used in the design calculations…

dear sir, i want to know how W/C ratio is selected for high strength concrete. in IS 10262-2009 there no provison for it.is there any graph or table or any method for W/C other than trial and error method.

sir please send me m40,m50,m60 grade concrete mix desion

sir,please tell me how to select W/C ratio to produce M60 grade concrete.i used metakaolin with cement and BASF Glenium B276.please send me method other than trial and error method.Also send rang of W/C for high strength concrete.please send me as soon as possible i want to start my project.

sir am new rech so pls give me the m500 grade and rato pls sir

give me M60 Grade concrete mix design as per IS 10262-2009

please send me m60 grade SELF COMPACTING CONCRETE mix design as per IS 10262-2009 or any IS

sir,pls send me the mix design for grade 20 and grade 25 concrete. i am doing a project.sir pls kindly send.

sir i want to know the mix design for M150 ……and what will be it’s strength

Sir im doing a project on m120 grade concrete .please provide me information on mix design proportions of m120 grade concrete

pls send m40 and m60 m120 grade mix design sir. im doing project, pls provide information, thanks and regards

i believe its 4.668 L / m3, instead of 4.668ml.

what is the weight for one unit metal

sir i wana know mix design of M65,M75,M85
