What is the process called when a smooth board attached to a handle is pushed and pulled across the surface of the freshly poured concrete? finishing C floating flushing screening

## Step 1<br />The problem describes a process in which a smooth board attached to a handle is pushed and pulled across the surface of freshly poured concrete. This process is known as "floating". <br /><br />## Step 2<br />Floating is a method used in concrete finishing where a smooth, flat board (often referred to as a float) is dragged across the surface of the concrete. This action helps to smooth out the surface and remove any air bubbles or imperfections. <br /><br />## Step 3<br />The other options provided, "finishing", "flushing", and "screening", do not accurately describe this specific process. "Finishing" is a more general term that refers to the final steps in a process, but it doesn't specifically describe the action of smoothing the concrete. "Flushing" typically refers to the process of cleaning or clearing something, and "screening" generally refers to the process of separating or filtering something.
