Iron oxide red (FEPREN TP 303, Czech production) is a pigment widely used in the construction industry for coloring various materials. The advantages of its use include not only a high degree of coloring, but also versatility of use.
Areas of use
Red iron oxide pigment has become an important component in the construction industry. Here are its main areas of application:
- concrete painting. The pigment allows you to give the material a red color, which makes it more aesthetically pleasing and meets the requirements of the project;
- paving slabs. Used for coloring paving slabs. Provides long lasting rich color;
- roof tiles. The pigment has become widespread in the production of tiles in order to create a variety of shades. A material with a beautiful color will make the roof more stylish and modern;
- fake diamond. Red iron oxide is used to color artificial stone, making it more natural and attractive;
- production of paints, primers and fillers.
Recommendations for insertion into concrete
The recommended percentage of red iron oxide added to concrete is 2-5% by weight of the binder (cement). The exact dosage depends on the desired shade and color of the final product, and on economic feasibility. It is important to maintain optimal proportions, since an excess amount of pigment can lead to negative consequences. An increase in the input percentage of more than 5% leads to an increase in the fine fraction, which can negatively affect its structure, an increase in the water requirement of the concrete mixture (it complicates the process of laying and forming), and a deterioration in technological properties, namely strength and frost resistance.
