Concrete Specs

Concrete Specs

Listed below are some different types of Concrete Specifications. These are created by the level of Grinding, the deeper we Grind the more stone is achieved. Every concrete contains aggregate in it.

Full Exposure

Full exposure, this is where the Floor is ground to show maximum amount of aggregate as possible.

Concrete Requirements- Concrete needs to be preferably 25 mpa of strength or higher and well cured. No vibrator is to be used in the top 100 mm of the Concrete slab so to minimise areas with no stone. Also care has to be taken when laying the Concrete eg- Screed Marks, Foot Prints etc. because of the risk of pushing the aggregate down too far.
Full Exposure

Random Exposure

Random Exposure, this is where the floor goes from nil exposure to full exposure of aggregate.

Concrete Requirements- Concrete needs to be preferably 25 mpa of strength or higher and well cured. Vibrator can be used with this throughout the whole slab. Also care has to be taken when laying the Concrete eg- Screed Marks, Foot Prints etc. because of the risk of pushing the aggregate down too far. This Floor would be the most popular out of them all.
Random Exposure

Salt & Pepper

Salt and Pepper, this is when the concrete is ground lightly to expose as least as possible.

Concrete Requirements-Concrete needs to be preferably 25 mpa of strength or higher. Vibrator should be used and floor should be as flat as possible. In regards to this floor the concrete should be left with a burnished finish by a helicopter so it is completely smooth.

Cream Finish

Cream Finish, this is where the floor has nil exposure.

Concrete Requirements- Concrete needs to be 32 mpa strength or higher and well cured. The concrete has to be completely flat and hit with the helicopter to achieve a burnished finish multiple times so it leaves the concrete completely smooth
