| Color Type | Description |
|---|---|
| Red Iron Oxide | The most common type of iron oxide, it’s used in paints, rubber, cement, and construction. |
| Yellow Iron Oxide | A lightfast and opaque pigment that’s often used in cement and lime. |
| Iron Oxide Black | An inorganic colorant that’s used in concrete, roofing tiles, and more. |
| Brown Iron Oxide | A man-made, non-toxic pigment that can be used in fine art and exterior applications. |
They are highly useful to make concrete paver blocks more robust with enhanced durability. Using block hardeners makes the concrete blocks up to 300 times stronger than conventional concrete blocks and bricks.
What is the use of hardener chemical?
One common use for liquid hardeners is to improve the surface hardness of newly poured concrete. This can help to prevent wear and tear, as well as make the surface more resistant to stains and other types of damage. Liquid hardeners are also often used to densify and seal existing concrete surfaces.
