The purpose of screeding concrete is to:

1. enhance the strength

2. level the surface by removing excess concrete

3. help it cure faster

4. increase its durability

The correct answer is: level the surface by removing excess concrete

Screeding concrete is the process of leveling the surface by removing excess concrete to ensure a smooth, level finish. This step is crucial in creating a flat and even surface that is ready for further finishing techniques or for placing objects on top of the concrete without any issues. Enhancing the strength, helping it cure faster, and increasing durability are important aspects of working with concrete, but these are not direct purposes of screeding. The primary objective of screeding is to level the concrete surface by removing excess material to achieve a desired flatness.
