Which of the following steps is performed immediately after floating?

Troweling is a crucial step performed immediately after floating in the finishing process of concrete surfaces. During troweling, the surface is smoothed out further and any imperfections from the floating process are addressed. This step helps in creating a denser and more durable surface by compacting the concrete, which reduces the formation of voids and increases strength.

The troweling process involves the use of a hand trowel or power trowel, and is essential for achieving a high-quality finish that can withstand various environmental conditions. It also allows for the application of any additional treatments, such as sealers, that might be needed for the concrete surface.

The other options relate to different steps in the concrete finishing process, but they occur at different stages. Bleeding refers to the process of moisture rising to the surface after placement; screeding is used to level the concrete before floating; and edging is typically done after troweling to create clean edges around the slab. Understanding the sequence of these processes is key to achieving a well-finished concrete surface.
