Provides inorganic iron oxide pigments for masonry and concrete industry.

When mixed with water cement becomes a paste that will then chemically set hard. The reason we have to add Ballast is to add strength and volume as the cement alone is not strong enough. There are many different types of concrete depending on its uses, the most common are high strength and water tight, general use and foundations. High Strength Concrete. Ballast. This ratio will give you high strength concrete with water tight properties making it great for ponds and structural uses such as concrete panels and building slabs. General Use Concrete. Ballast. Great for concrete being used to lay paths, floors, general landscaping and driveways. Foundations and large Volume Concrete. Ballast. This mix ratio mainly used when a large amount of concrete is being used to fill strip footing trenches, makes for a solid and stable foundation filling from bed rock to ground level.
