The mix proportion of this grade is approximately 1:0.75:1.5 (Cement: Sand: Aggregate). A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is presented in the article.

Average of 28 days strength is ( 41.52 + 41.43 ) / 2 = 41.48 N/mmWhich is less than 42 MPa. As we described, as per MORTH 5th revision, our requirement in 28 days for M30 is 42 MPa.So now we are going to decrease the water-cement ratio a bit.Previously we selected 0.39 water-cement ratio.

( for pumpable mixes 10 % coarse aggregate should be decreased and the same percentage of fine aggregate is to be increased)Volume of coarse aggregate = 0.747 X 0.66 = 0.493 cum Note : 1.

Water content with using appropriate dosages of super plasticisers =186 X 0.7 =130 kg/cum From figure 1 Page no 4 of IS 10262 : 2019 free water cement ratio required for the target strength of 38.25 N/mm2 is 0.42 for PPC (curve 2) which is less than the maximum value of 0.45 prescribed for mild exposure for reinforced concrete as per Table 5 of IS 456 :2000 hence OK Hence Volume of coarse aggregate and fine aggregate = 1 – (0.112-0.134–0.0015-0.005) = As per clause number 6.2.7 , Table 10 page number 10 of IS 10262 : 2019 . M30 Grade of Concrete Mix Design Calculation Formula We are describing formula of concrete mix design calculation for M30 Grade of Concrete Mix Design but you can use this formula for any grade of concrete Formula : Volume of material content = material weight / (material specific gravity * total volume) Volume of concrete = 1 Cu.M.

Here, M represents ‘MIX’ and 30 represents the characteristic compressive strength of a 150 mm cube of concrete at 28 days of curing in N/mm^2. Considering the durability requirements too. ... fly Ash Percentage in PPC Cements. a) Grade designation : M30 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 320 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.45 (Table 5 of IS 456:2000) For Zone II 20 mm nominal maximum size aggregate, Volume of coarse aggregate and fine aggregate = 0.66 per unit volume .

If you are getting any doubt, please scroll above for full details.Course Aggregate Proportions ( 20 mm : 10 mm ) : 50%Aggregate = 1- ( cement volume + water volume + admixture volume )Now we got a volume of each material for use in concrete.Mass of coarse aggregates 20 mm = 0.742 X 0.60 X 0.50 X 2.885 X 1000 = 642.2 Kg.Mass of coarse aggregates 12.5 mm = 0.742 X 0.60 X 0.50 X 2.857 X 1000 = 636 kgMass of fine aggregates = 0.742 X 0.40 X 1.00 X 2.723 X 1000 = 808.2 KgNow we calculate the quantity of the material for a trail mixWe are repeating the procedure because it’s very important tips for a trail mix.As we described, our requirement of a slump is 125 – 150 mm at the site.We have to check the slump after each 30-minute interval of up to 120 minutes ( 2 hours).We are repeating this because it’s very important tips for trial cube casting.As we described before, we cast 12 numbers of a cube for compressive strengthAs we described before that our target means strength for M30 is 42 Mpa.minimum compressive strength required in 3 days – 40 % – 17 Mpaminimum compressive strength required in 7 days – 80 % – 34 MpaSo as you can see from this result described above, we got a good result in 3 days, 7 days and 28 days. Two more trials having variation of + or – 10 percent of water – cementitious material ratio shall be carried out and a graph between these water cementitious materials ratios and their corresponding strengths shall be plotted to work out the mix proportions for the given target strength for field trials .

Average of 28 days strength is ( 42.47 + 42.5 ) / 2 = 42.49 N/mmWhich is greater than 42 MPa. OPC 53 grade confirming … As we described, as per MORTH 5th revision, our requirement in 28 days for M30 is 42 MPa.So now, we got the perfect proportion for the M30 grade of concrete.Amazing post, thank you for sharing this knowledgeable post, really this is very helpful.Difference Between Flexible Pavement and Rigid PavementDifference Between Lap Length and Development LengthDifference Between Plasticizer And Superplasticizer in CivilDifference Between Plinth Level, Sill Level, and Lintel Level.Difference Between Pre-Tensioning and Post-TensioningHow to Structural Design a Building/House Step by Step Part-1 (One Way Simply Support Slab)How to Structural Design a Building/House Step by Step Part-2 (Two Way Simply Support Slab)How to Structural Design a Building/House Step by Step Part-3 (Slab Beam Design)How to Structural Design a Building/House Step by Step Part-4 (Column Design)House Construction Cost Calculator Excel Sheet For Ground Floor(G.F.), G.F.+1, G.F.+2, G.F.+3,IS 516:1959 Most Important Point (Method of Tests For Strength of Concrete)Selection of Water Cement Ratio for M30 Grade of Concrete Mix designCompressive Strength of Trial Cubes for M30 Grade of Concrete Mix DesignTrial Mix: 2 ( for M30 Grade of Concrete Mix Design) © 2014 bloggercivil.com.
