Study of red ceramic residues as pigments in matrices based on white Portland cement

ABSTRACT: The present study evaluated the use of red ceramic residues (RCR) as pigments in matrices based on White Portland cement. Five mortars were prepared for study: control mortar (M0), at 1:2,3 ratio (cement: sand) and water/cement 0.60, other four containing RCR 10% (M10), 20% (M20), 50% (M50), 100% (M100) volume replace to sand. Colorimetric tests indicated a significant increase coloring, due used. Tests resistance compression strength results there was an substitution content sand by RCR. In flexural tensile no influence contents up 50%. Therefore, showed potential pigmentation product can contribute compressive cement-based matrices.
