Paver block color pigments.gments from the product ranges Bayferrox® and Colortherm® can be used to add color. They display high quality levels in terms of color strength and color consistency. Because of their chemical structure these products are highly weather stable, lightfast and UV-stable and are very well suited for the coloring of construction materials. At the same time, the LANXESS production processes ensure low environmental impact.
The color range of the entire Bayferrox® and Colortherm® product portfolio includes Yellows, Reds, Greens, Browns and Blacks. In between these colors a wide variety of additional shades are possible. The shades tend towards the opaque colors found in nature, and thus fit harmoniously with the environment. Pure colors like yellow can be made by using white cement. Brilliant, glossy shades, like those obtained in plastics and surface coatings, are very difficult to produce in building materials because of the composition and structure of the concrete.
The production of multi-colored concrete paving blocks and paving slabs is in principle the same. To achieve the two-color or multi-color effect, it is important that differently colored concrete mixes are not completely mixed with one another when they are processed.
Depending on the proportions in which the two, or more, colored concrete batches are mixed, the emphasis can be placed more on one or other of the colors. Depending on the machinery available. different production procedures are possible.
The Global Competence Center Construction will gladly answer individual customer inquiries with respect to this field of application or provide further information about LANXESS pigments.
