Which tool is commonly used for hand spreading concrete in slabs?

Explanation:
Spreading fresh concrete by hand is about moving and placing the mix evenly across the slab and into corners before it stiffens. A short-handled, squared-ended shovel is the best tool for this task because its compact head and flat, squared edge let you scoop, push, and pull material into tight spots, fill voids, and create a relatively uniform layer right against the forms. The squared end helps you reach into corners and along edges with good control, which is essential in the initial spreading stage. Magnesium floats, edgers, and bull floats are finishing tools used after the concrete has begun to set: floats smooth the surface and bring cream up, edgers shape the concrete along the edges, and bull floats level and push down high spots to prepare for final finishing. For the actual hand spreading, the shovel is the most effective choice.
