What is the Difference Between Screed and Concrete?

Screed and concrete are very similar in many aspects. They are both constructed from the same materials: cement, water, and aggregates (usually sand, stone, or gravel) and are both used for flooring purposes, although concrete also has many other uses. However, screed and concrete also have many differences, including:

How They Are Made

Although both screed and concrete are made using cement, water, and aggregates, the main difference between these two materials is the type of aggregate that is used. The aggregate used in screed is fine, sharp sand that has a maximum grain size of around 4 millimeters, whereas the aggregate used in concrete is much coarser, usually gravel, with pieces around 20 millimeters in size. This coarser aggregate is what gives concrete its durability and strength.

Their Physical Appearance

Although at first glance it may be hard to tell the difference between the two, there are some tell-tale signs that will allow you to identify if you’re looking at screed or concrete. Concrete has a rough texture and if you look closely, you’ll be able to spot bits of gravel and stone in the mix. If what you’re looking at is smooth and has a fine-grained look, it’s probably screed.

What They Are Used For

Because screed is used as a top layer for concrete floors, rather than for structural work, the use of it is somewhat limited. Screed is usually used for:

• Concrete floors
• Underfloor heating systems

Concrete, on the other hand, is a perfect material for building because it is much stronger and very versatile. It is used for a variety of purposes, including:

• Floors
• Roads
• Foundations
• Walls
• Driveways
• And much more
