3. Target Mean Strength and Mix Proportioning
- As per MORTH the Target Mean Strength for M-60 Grade = 73Mpa
4. Target Mean Strength and Mix Proportioning
- As per technical specification max Water/Cement + Binder = 0.4
5. Selection of water/Cement Ratio (W/C)
Ref Tab 2 , IS 10262 , Maximum water content per cum for 20mm Aggregate = 186 litre for 50 mm slump= 186 + (0.12 * 186) (add 3% for every 25 mm increase )= 208.32 litBased on trials with super plasticizers, water content reduced by 15%,hence the arrived water content = 177.07lit, So Let us add water 177 lit
6. Cementious content Calculation
Water-Cementitious Ratio = 0.33Cementious content (Cement OPC 53 + GGBFS) = 536Say Cementitious content = 540 kg/m3Cement = 390 kg/m3Based on experience and lab trials,GGBS =150kg/m3 (Taking GGBS 27.77%)Based on experience and lab trials, Based on experience and lab trials, super plasticizer = 0.67 %
7. Calculation Aggregate content Calculation
Ref Tab 3 of IS 10262 , for Sand Zone II , volume of coarse aggregateper unit vol of total aggregate for 0.5 water-cement ratio = 0.62Adjust for W/c ratio : Add @ 0.01 for every decrease in 0.05= 0.034Therefore , corrected proportion = 0.654Adjust for pumpability , i.e decrese by 10% = 0.59 %Based on experience Considering Volume of coarse aggregate = 0.53Therefore, Volume of Fine aggregate = 0.47
8. Mix volume Calculation per cubic meter of concrete
a) Volume of concrete = 1 m3 b) Volume of cement = (Mass of cement /specific gravity of cement) × 1000 =390/(3.15×1000)= 0.124 m3c) Volume of GGBFS=(Mass of GGBFS/specific gravity of GGBFS )× 1000=(150/2.91)x1000=0.0515 d) Volume of water = (Mass of water /specific gravity of water)× 1000 = 0.177 m3 e) Volume of admixture = (Mass of admixture /specific gravity of admixture)× 1000 = (540×0.67)/(100×1.096×1000)=0.0033 m3 f) Volume of all in aggregate =[a-(b+c+d+e)] =1-(0.124+0.0515+0.177+0.0033)=0.6442= Say 0.644 m3 g) Mass of coarse aggregate(CA) 1) 20 mm = f × volume of CA × sp. gravity × % of 20mm × 1000 = 0.644*0.53*2.66*0.1*1000= 90.791 kg/m3, Say 91 kg/m3 2) 12 mm = f× volume of CA × sp. gravity × % of 12mm × 1000 = 0.644*0.53*2.64*0.9*1000 = 810.976 kg/m3, Say 811 kg/m3 g) Mass of Fine aggregate = f × volume of FA × sp. gravity × 1000 0.644*0.47*2.59*1000 = 783.941 kg/m3 Say 784 kg/m39. Details of Mix Design
- cement = 390 kg
- GGBFS =150 kg
- 20mm = 91 kg
- 12mm = 811 kg
- Crushed stone sand = 784 kg
- Chemical admixture = 3.62 kg
- Free Water = 177 kg
- Water-Cement Ratio = 0.33
- Concrete density = 2406 kg/m3
