What is procedure to apply plum concrete?

To apply plum concrete, first, prepare the site by clearing and leveling the area where the concrete will be poured. Mix the concrete with a specified ratio of coarse aggregates, including larger stones or boulders (plums), to reduce the amount of cement needed. Pour the mixture into the desired formwork, ensuring proper placement of the larger aggregates for structural integrity. Finally, finish the surface as needed and allow the concrete to cure properly for optimal strength.
