Recycled Concrete Sand (PTY) Ltd is a dynamic innovative company based in Cape Town South Africa.
The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes, especially in Concrete.
Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials. Granite fines or rock dust is a by-product obtained during the crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by-product as a partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available.
Charle Ehlers, the Founder, and CEO of Recycled Concrete Sand ( RCS) have a wealth of experience as a Controlled Blasting Specialist and a qualified Quarry Master. In our industry, we are very conscious of the environmental impacts we have in our daily operations. RCS has identified key sustainable solutions in the production process of aggregates that will have a ” greener impact” on the way the manufacturing process is conducted.
Concrete is the most popular building material in the world. However, the production of cement has diminished the limestone reserves in the world and requires a great consumption of energy. River sand has been the most popular choice for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of river sand deposits, and a concomitant price increase in the material.
At RCS we have made it our mission to make use of cost-effective, environmentally friendly alternatives for cement and river sand that are preferably byproducts. Fly ash (pulverized fuel ash) is used extensively as a partial replacement for cement. By combining various recycled materials such as Fly-Ash and Quarry Dust we provide Concrete Sand to the Building Industry that is more cost-effective, and environmentally friendly, at the fraction of the cost without compromising the strength and workability of the concrete.
