Troweling of newly placed concrete is performed directly after which step?

Troweling of newly placed concrete is a critical step that occurs after floating. The floating process helps to level the surface and fill in any voids or imperfections immediately after the initial set of the concrete. This task involves using a float tool to create a flat and even surface by smoothing out the concrete and ensuring that any aggregate is brought below the surface.

Once the floating is complete, the concrete has reached the right level of hardness where troweling can be performed effectively. Troweling further refines the surface, creating a finer finish and sealing the surface to reduce porosity. This step is crucial for achieving the desired aesthetic and functional characteristics of the concrete, such as durability and resistance to water infiltration.

The importance of troweling following floating highlights the sequential nature of concrete finishing processes, where each step builds upon the previous one to enhance the overall quality of the finished product.
