Sweeping concrete and stone floors but dust keeps resurfacing?

Dusting Facts

What is concrete and stone dusting?
Formation of loose powder resulting from disintegration of surface of hardened concrete is called dusting.
Chalking or powder at the surface of a concrete or stone slab is dusting. It can easily be scratched with a nail or even by sweeping.

Where is this commonly found?
This problem is commonly found in basements and old farmhouses.

Why do concrete or stone floors dust?
Dusting is caused by the wearing surface being weak and the mixture and application not properly bonding the fine aggregate particles. The weaker the wearing surface, the more dust you get. Also, the older the wearing surface, the more dust you get.
Concrete floors are filled with microscopic pores. Each pore has edges, which abrasion can break off. Over time, this creates more dusting. It also creates more edges for more breaking and more dusting.

Time traffic and abrasion combine to break off concrete pore edges, contributing to dusting.

How can one minimize dust on concrete surfaces?
Proper finishing and curing of the surface helps minimize dust, but won’t eliminate it. This includes but is not limited to:
– Proper combination of water and concrete mixture
– Proper mixing of wet concrete
– Proper drying of concrete.
