What is the purpose of using a vibrating screed?

The purpose of using a vibrating screed is to ensure proper compaction and levelness of concrete. When concrete is poured, it often contains air pockets and can have inconsistencies in its surface. The vibrating screed, as it moves across the surface of the freshly poured concrete, effectively vibrates the concrete, which helps to eliminate air bubbles and allows the concrete to settle into a more uniform density. This action not only enhances the strength of the concrete by improving compaction but also aids in achieving a flat, level finish.

While adding air to the concrete mix, removing excess water, or mixing the concrete are important aspects of concrete work, those functions are not performed by a vibrating screed. Its primary role is focused on compaction and levelness, making it an essential tool for ensuring high-quality concrete surfaces.
