Application of iron oxide red pigment in concrete

Wandering the school playground, passing by the airport runway, and the surrounding city walls of the tourist palace, we saw all kinds of reds. There is Iron Oxide red in this red, which is the crystallization of Iron Oxide red used in the concrete field. So, how to use Iron Oxide red in the concrete field?

Iron oxide red is used as a pigment or colorant in various types of concrete prefabricated parts and building materials, and can be directly transferred to use, such as various indoor and outdoor colored concrete surfaces, such as walls, floors, ceilings, pillars, porches, Pavements, parking lots, stairs, stations, etc., various architectural ceramics and glazed ceramics, such as face tiles, floor tiles, roof tiles, panels, terrazzo, mosaic tiles, artificial marble, etc. The specific usage method is:

The amount of Iron Oxide red in concrete products is limited to 1-10%. If the limit is too high, the mechanical strength of the products will be reduced. Usually 5-8% is appropriate. Iron Oxide red contains lead and zinc oxides. These two compounds affect the setting time and setting strength.  

Concrete products sometimes need to be cured by heat and pressure above 200°C, so black and brown Iron Oxides that can be converted into iron red at 180°C must be treated with thermal stability first. If used on terrazzo, the bottom layer is 2 to 3 cm thick, and the surface layer is 15 cm thick.  Iron oxide red is used in the concrete field. It utilizes the outstanding weather resistance, alkali resistance and light resistance of Iron Oxide red. These functions are not compatible with other inorganic or organic pigments.

In recent years, in order to protect land resources, my country has banned the use of clay bricks and tiles, which has promoted the development of Iron Oxide red in the concrete field. High-quality Iron Oxide red is more and more popular with manufacturers. Our company produces Iron Oxide red and other pigments. , Has accumulated more than 10 years of experience in the concrete application field.
