Color Considerations For Modular Concrete Products
Color Variations
As in all natural materials, color in paving stones has inherent variations. Paver color is affected by the variances in the raw materials, concrete mixture moisture content and climactic conditions and other variations. Therefore, the colors shown are approximate representation of standard paver colors, but should not be expected to be an exact match of what will be delivered.
The Nature of Efflorescence
Another cause of color variations in pavers may be the natural phenomenon called efflorescence. Efflorescence, a deposit of white salts consisting of mostly calcium carbonate, may appear as a white powder on the paver surface and in no way affects the structural integrity. This phenomenon occurs in all concrete and although it cannot be completely prevented from occurring, efflorescence generally will weather off and disappear over time or can be removed with cleaners at the job site.
