Concrete Grade C60/20: The required concrete grade for these structural elements fall under the bracket of standard grade concrete or the C40/20 – C45/20 concrete grade. In addition, concrete grade has several mix proportions. These are denoted with 1:2:3 or cement:sand:coarse aggregates.
Use a maximum .45 water to cement ratio for concrete with severe or very severe sulfate conditions per the 1997 Uniform Building Code (Table 19A4) Water permeability increases exponentially when concrete has a water cement ratio greater than .50. Durability increases the less permeable the concrete mix is. Strength improves with lower water cement ratios. A .45 water cement ratio most likely will hit .

The mixes of grades M10, M15, M20 and M25 relate approximately to the mix ratios (1:3:6), (1:2:4), (1::3) and (1:1:2) correspondingly. 3. Designed Mixes: In these mixes the performance of the concrete is indicated by the designer but the mix ratios are obtained by the producer of concrete, apart from the minimum cement content is put aside. It is the most authentic method for choosing the mix ratios with .

strength of concrete at 28 days, k = usually as per is s = standard deviation.
Normally water cement ratio falls under to as per IS Code 10262 (2009) for nominal mix (M10, M15 .. M25) We all know that water cement ratio will directly affect the strength of concrete.
In order to restrict the maximum water content per cubic meter of concrete to 190 litre considering the guidelines as suggested in IRC44 IS 10262 (for 20 mm maximum size of coarse aggregate), and greater fineness of available cements, w/c ratio may be selected as for 360 and 380 kg cement per cubic meter of concrete and for 400 and 420 kg cement per cubic meter of concrete.
Mix ratio for M35 concrete is 1:: . compressive strength is 35N/mm2 28 days. . 1 part of cement, of sand, parts of coarse aggregate.
Concrete Mix Design As Per Indian Standard Code In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed cementaggregate ratio which ensures adequate strength are termed nominal mixes.
w/c ratio and a certain minimum grade of concrete for that particular exposure. ... Concrete mix design is defined as the appropriate selection ... k = usually as per is s = standard deviation. Specified and Target Mean Strength 44. Grade of concrete
Mix Ratio and Grade of Concrete | About Civil Engineering. Mix Ratio and Grade of Concrete : denotes its strength required for construction. For example, M25 grade signifies that compressive strength required for construction is 25MPa. The first letter in grade "M" is the mix .
For M40 grade of concrete the ACI method was failing to achieve the target strength, whereas the rest of the methods achieved strength more than the target strength. The DOE, BIS and USBR methods attained , 104% and % of strength respectively.
2006 Edition (b) The test result for that sample shall not be used to assess compliance as stated in Clause (1)(b) and shall not be used to calculate the standard deviation. (4) For designed mix concrete with grade strength of less than 20 MPa, compliance criteria C3 shall apply.
