There are a number of different types of concrete aggregate with contractors selecting their aggregate on the basis of the type of job being performed.
Aggregate concrete floor texture.
Aggregate particle shape and surface texture are important for proper compaction deformation resistance and workability however the ideal shape for hma and pcc is different because aggregates serve different purposes in each material.
Coating finish texture a cft a provides a slight surface texture that results from the physical properties of the resin an underlying texture of the substrate a flat flake aggregate or a fine aggregate contained within the coating.
If intensive surface preparation is required for your acid stain project stone aggregate may be exposed after heavy grinding or brushing machines are used to remove surface contaminants depending on the quality of the concrete floor sand and or small stones can be unintentionally revealed leading to a rough or highly textured surface.
It also effects pumpability and durability of concrete.

There are different methods by which concrete can be removed to get certain texture pattern and slip resistance.
In hma since aggregates are relied upon to provide stiffness and strength by interlocking with one another cubic angular shaped particles with a rough.
Grading of aggregates depends on the proportions of coarse and fine aggregate.
Exposing the aggregate in concrete can also create grain texture and pattern in floor surfaces which is particularly useful for areas requiring greater slip resistance especially when wet.
Contractors placing decorative exposed aggregate concrete where appearance is a prime concern should pay special attention to the aggregate shape texture color and overall appearance to yield the best looking final product photo 8.
If such special measure is not considered at concrete mix phase aggregate would not remain close to concrete surface after compaction which is not desirable in the case of exposed concrete floor.

Concrete aggregate is a material which is mixed with cement to create concrete which is hard strong and long lasting.
If grading of aggregate is varied it also changes cement paste content cost economy workability of the mix.
The uppermost layer of concrete or surface mortar can be removed in a number of ways each with subtly different results.
