Concrete Design Mix for Varies Grade of Concrete

Concrete Design Mix for Varies Grade of Concrete Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. So, concrete mix design can be stated as Concrete Mix design of M20, M25, M30 and higher grade of concrete can be calculated from example below. rete Mix = Cement:Sand:Aggregates.

Concrete Mix design of M20, M25, M30,M35,M40,M45,M50 grade of concrete can right proportions of cement, sand and aggregates for concrete to achieve target strength in structures below.

Admixture    :  0.6%

Fresh concrete density:  2414 Kg/ m3

Note: sand 775 + 2% moisture, Water 185 -20.5 = 164 Liters,

Admixture = 0.5% is 100ml

M30 ( 1 : 2 : 2.87)

Cement     :  380 Kg/ m3

20 mm Jelly    :  654 Kg/ m3

12.5 mm Jelly   :  436 Kg/ m3

River sand    :  760 Kg/ m3

Total water    :  187 Kg/ m3

Admixture    :  0.7%

Fresh concrete density:  2420 Kg/ m3

Note: Sand = 760 Kg with 2% moisture (170.80+15.20)

M35 ( 1 : 1.79 : 2.57)

Cement     :  410 Kg/ m3

20 mm Jelly    :  632 Kg/ m3

12.5 mm Jelly   :  421 Kg/ m3

River sand    :  735 Kg/ m3

Total water    :  200 Kg/ m3

Admixture    :  0.7%

Fresh concrete density:  2400 Kg/ m3

Note: sand = 735 + 2%, Water = 200- 14.7 = 185.30,

Admixture = 0.7%
