Advantage and Disadvantage of Colored Concrete in Structural Engineering

Abstract

This paper is about the impact of the colored pigments on the concrete and its various properties. A number of colored pigments found in the Egyptian markets were used; some of these pigments are made in China and others are made in Germany. The effects of these materials were studied on the fresh and hardened concrete, the consistency studied by slump test, the strengths studied by compressive strength test and the durability studied by abrasion test and permeability test. It is found from this research that colored pigments does not affect in the concrete mechanical properties in a danger way, Colored concrete must constructed with accuracy and with a good experience.
