Re: Stone dust used for concrete mixing There are all kinds of alternative aggregates for concrete, but unless you have a way to control the material, you risk getting unexpected results. For example, sea shells have been used in concrete with good results but if you pick up salt and other impurities along with them, it damages the concrete.

Stone Dust Darker, coarser version of sand we called stone dust. It is produced by running stones through a crushing machine to make the crushed aggegates. Stone dust is is much easier to grade and work than sand, that' why is used as the final base and setting bed in many pavers projects, patios, hardscape blocks, walkways and driveways.

Because sand comes in many degrees of fineness and coarseness, not all types are suited for use as a paver base. The Interlocking Concrete Pavement Institute recommends washed concrete sand as the best base sand for pavers. Concrete sand, also known as bedding sand, is coarse and doesn’t trap excess moisture beneath the paver surface.

We are using the carborundum stone to sand natural stone paving slabs. If you’re paving is made from coloured man-made concrete you could expose the aggregate the paving was made with by sanding with a carborundum stone. Before you begin, it may be worth doing a small test patch of to check the results.

Mortar additives are particularly effective in giving both engineered and natural pavers the best possible chance of being installed neatly and adhering to a concrete foundation over the long term. Using a standard mortar mix consisting only of sand and cement is not sufficient for engineered stone applications. Large format is not the same

In contrast to stone dust, concrete sand provides superior performance over time. It doesn't eat away at pavers, it affords excellent drainage, and it compacts well. The coarse texture also acts to hold pavers in position, providing a stabilizing buffer that allows the ground underneath to shift without shifting pavers.
