Anyone have any indicative tables showing ratios tonnes rebar to M3 concrete for rc structures... possibly showing breakdown into elements... Bases, walls, slabs, soffits. Piles etc.?

    Thanks Armando... I managed to find some more information yesterday... from a UK Civil’s Design Group

    Specific data for "Water Retaining Structures"
    Walls 100mm thickness per metre retained height rebar density 120kg/m3
    Bases wall thickness plus 50mm rebar density 130kg/m3
    For piled bases the density increases to 150kg/m3
    General note - for non water retaining structures reduce the densities by 25%.
