Degradation of Colored Concrete Elements due to Frost

Abstract

This article is focused on changes in the properties of colored concrete due to frost. In contrast to conventional concrete structures, fair-faced concrete is exposed to external conditions and is therefore also prone to degradation of its surface. The durability of the surface layers is mainly reflected in the color saturation and resistance to mechanical damage. Therefore, the paper focuses on measuring the change in color and strength characteristics after 75 cycles of frost resistance. The measurement was performed on concrete samples colored with yellow, red and green powdered metal oxide-based pigments. Based on the results, we can concluded the frost resistance of colored concrete depends primarily on the type of pigment used.
