    Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid. Some concretes are even designed to harden more quickly for applications that require rapid set time. Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls.

    Load Calculation on Column: we know that the Self-weight of Concrete is around 2400 kg/m3, which is equivalent to 240 kN and the Self-weight of Steel is around 8000 kg/m3. So, if we assume a column size of 230 mm x 600 mm with 1% steel and 3 meters standard height, the self-weight of the column is around 1000 kg per floor, that id equal to 10 kN.
