I have recently made up 3 x 150mm concrete cubes using the mix for reinforced concrete work that being (1:2.5:3.5).

I used the same water to cement ratio you suggested that is 0.57.

The cubes were left to cure in the laboratory and not within a tank of water.

I tested one of the cubes at 7 days and to which it achieved 8.137N/mm^2.

My questions are,

  1. Does 8.137N/mm^2 sound about right after 7 days of curing?
  2. Can you tell me what the ‘C’ grade of concrete this mix is?
  3. What result should I expect t 28 days when the strength of the remaining two cubes are at 99%

    Answer-

    1. Without knowing the ultimate strength of the concrete mix, the results obtained on the 7th day can not be declared as right or wrong.
    2. Considering the results obtained on the 7th day, i.e, 8.137 N/mm2, the designed strength of the concrete mix shall be M12.
    3. The results obtained on the 7th day must be 66% of the ultimate strength. So the ultimate strength of the concrete for the mix that can be expected on 28th day shall be 12 N/mm2.
