Abstract
A method for forming a concrete floor as a monolithic unit is disclosed wherein wet concrete mix is deposited and screeded to achieve a generally uniform thickness of concrete with the aggregate being densified or settled to produce a thin upper layer formed substantially from sand and cement, thereafter floating the concrete to substantially remove surface irregularities, and then grinding the upper surface of the concrete floor after it is hardened to produce a flat surface having a "sanded" finish.
