Construction Masonry Products Concrete and masonry building products

A large range of attractive and functional concrete and masonry building products are produced utilising ground calcium carbonate. Typically, if concrete and masonry are to be used in an area that needs to look attractive, then high-brightness limestone is used, and usually in an array of sizes (from smaller sands and aggregates to coarser stones). Where colour is not as important, washed marble sands from the production of limestone can be utilised. They are made use of either alone or blended with other sizes to create the required look and function. Ground calcium carbonates add to the effective production and fitting of many masonry products.

Terrazzo Marble

Terrazzo is a man-made commodity, created using natural ingredients. It is basically comprised of marble chips or other aggregates, cement and coloured oxides. The product’s free form allows it to be used in many precast shapes, which is ideal for tailor-made products like steps, street furniture, toilet partitions, skirting, wall panels and in-situ flooring.

Calcium carbonate is employed in fine and coarse varieties as a filler for products requiring form and function.

Cultured Marble and Cast Polymer

Usually, the look of natural marble and granite is overshadowed by the price. Cultured marble, or cast polymers, offer the look without the price tag and are ideal for sinks, shower stalls, splash backs and bench tops. Our excellent quality calcium carbonates help to create beautiful, functional cast polymer products.

Typical products for industries utilising cast polymers are manufactured in a variety or particle sizes and resin demands. They can be utilised alone or with other cast polymers. Mixing a smaller-particle-sized filler with a larger-sized filler gives good pigment packing, reducing resin demand and improving polymer strength. The coarser grades will have the lowest resin demands, while the finer grades will yield a more uniform whiteness.

Bricks & Blocks

Clay makes an excellent insulator against the weather, and as such clay bricks and tiles are becoming more and more popular.

The three prime benefits of mixing calcium carbonate filler with clay to manufacture bricks and tiles are: to create a more yellow colour, to minimise shrinkage (vital when the end product is used in applications where shrinking is detrimental) and to minimise the amount of fluorine produced when clay is burned.

Applications utilising concrete blocks necessitate fillers with uniform colour and aggregate particle size distribution.
