      M20 grade of concrete is generally used. The cement content is different for different grades of concrete.
      Cement content in M20 grade concrete = 270 kg/m3

      Hello Thiru,
      I don’t design. I help people clear their doubts in design. Foundation design guide is available on my site. Go through it and design the steel reinforcement for the structure. If you have any doubts or something you don’t understand feel free to ask a question.
