Salt can also increase the freeze-thaw cycles if the temperature fluctuates between 15°F and 25°F.

Concrete scaling can occur in the absence of salts too if there were problems at installation.

In its simplest form, concrete is a mixture of paste and aggregates (rocks).

The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates.

Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Within this process lies the key to a remarkable trait of concrete: it's plastic and malleable when newly mixed, strong and durable when hardened.

These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks and superhighways, houses and dams.

The Portland Cement Association has sponsored research directed at extending the boundaries of technical knowledge in the field since 1916.

It addresses the properties of concrete needed in construction applications, including strength and durability, and provides guidance on all aspects of concrete from mix design to batching, mixing, transporting, placing, consolidating, finishing, and curing.

Salt does not damage concrete, but the effects of salt can. Salt does not chemically react with hardened concrete.
