If I looked on concrete factory better, I saw that produced concrete would be very fragile - because there is too much of stone - and lack of cement.
Current consumption is
44 % of stone
44 % of sand
22 % of cement
but it should be
22 % of stone
44 % of sand
44 % of cement
Please, change it.
Depends on the resistance you want to accomplish.
In my country we usually used the following mix of concrete for construction of houses:
100kg/cm2
1 cement
3 sand
5 stone
150kg/cm2
1 cement
2 1/4 sand
4 stone
175kg/cm2
1 cement
2 1/4 sand
3 1/4 stone
I always use the following for my work at home:
1 cement
2 sand
3 stone
The concrete you propose is really tough, I imagine that the retaining wall of a dam.
Thanks for this info.
My idea (and it is real) is that basic materials in concrete are only sand and cement - and stone is only for lesser consumption of other both materials (main matter of concrete).
