Mesh Reinforcement for Concrete Slabs: 3 Things You Need to Know
Posted on: 25 April 2019
When it comes to modern construction, few materials can boast the same popularity enjoyed by concrete. It has stood the test of time as a reliable and functional building material. Concrete delivers the results you desire regardless of the project you want to complete. Your options could range from commercial and residential buildings to paving and walkways. However, concrete still has a few weaknesses despite its ability to deliver excellent results. Using mesh reinforcement eliminates the weakness of concrete and improves its quality as a building material. Here are some important things you must learn about mesh reinforcement and concrete slabs:
1. The Mesh Manages Bleedwater
When builders lay fresh concrete, the material comprises a mix of cement, ballast, sand and water. Water makes the mixture plastic and easy to work with. Bleeding occurs when the solid contents of the concrete mixture move to the bottom and displace the water upwards. This happens due to the force of gravity. You can tell when concrete starts to bleed because it forms puddles of water on the surface as the cement settles at the bottom.
Reinforcing the concrete with mesh helps it bleed more evenly. The curing process will be uniform, which enhances the structural integrity of the structure in place.
2. Finishing the Concrete Surface
Mesh reinforcements do not limit you in terms of the finishes you can use for your concrete surface. Steel and synthetic mesh reinforcements permit the use of various finishes including exposed aggregate, pattern stamping, power troweling and brooming. If you decide to broom or rake the slab, it is advisable to pull the broom in one direction for a good finish. The synthetic fibres at the surface are not a cause for alarm because they will wear off in a short time.
3. You Can Control Surface Exposure of the Mesh
Surface exposure of mesh reinforcement is not a bad thing, especially when you are using synthetic mesh. However, it is judicious to keep the exposure in check, just in case it might have an effect on your finish. Strike off operations come in handy when you need to prevent exposure of your mesh reinforcement. You have three options at your disposal for the strike off operations. These are vibratory, laser and manual screed. They cause mild vibrations on the surface of the slab, bringing the loose paste to the surface of the slab. This ensures that the mesh settles properly in the slab with minimal chances of surface exposure.
