Q. Does the color or finish of fiber-reinforced concrete differ from regular concrete? A. The addition of fibers to concrete can influence its appearance and finish, especially if proper finishing techniques are not followed. Steel fibers that become exposed on the surface may rust over time when the concrete is exposed to the environment, potentially affecting its aesthetics. Using stainless steel or galvanized steel fibers can eliminate rusting in exposed steel fibers. While the finish of fiber-reinforced concrete (FRC) can be similar to that of regular concrete, visible fibers, especially on the surface, may give it a distinct appearance. Fibers do not inherently change the color of the concrete, as its color is primarily determined by the cement, aggregates, and any added pigments. However, visible fibers of a different color than the concrete matrix can influence the overall appearance. Proper finishing techniques are essential to ensure a smooth and aesthetically pleasing surface when using FRC.
