The usage of technology to drastically minimise the amount of cement in a product is within itself not only unique, but further adds to the reduction of greenhouse gasses emitted into the atmosphere. This may require several techniques, but one product has proven that it is able to achieve what many only strive for, by utilising recycled materials as opposed to cement.
Walls & Roofs spoke to Cyril Attwell, director of ARC Innovations, and developer of the EcOgrind product range, to delve deeper into these techniques used, how they benefit the industry, along with key projects that have made use of Ec0grind to significantly reduce the amount of cement used upon application.
“Ec0grind is a hybrid product utilising ARC technology, similar to the technology applied to the Gautrain, Portside building and Loeriesfontein Wind Farm,” highlights Attwell. “This technology utilises 97,5% by-products and in doing so, reduces the carbon footprint by approximately 97,5%. The standard Ec0grind is used for aesthetic finishes in low- to medium-impact areas such as showrooms, houses and offices.”
Replacing cement with by-products
By using this ARC technology, they are able to remove a large portion (95%) of Portland cement and replace it with by-products such as pulverised fuel ash (PFA), from coal-fired power stations with ground-granulated blast-furnace slag (GGBS), from iron purification to make a hybrid material which is part hydrate and part polymer.
“The production of Portland cement is one of the leading contributors to carbon dioxide emissions worldwide. The replacement of Portland cement with by-products will reduce the environmental and economical prices,” Attwell says.
EcOgrind will be marketed by A.SHAK PTY LTD in easy to use DIY packs through the Hardware retail sector to allow for smaller projects to be undertaken by homeowners. The EcOgrind system is ideal for bathroom floors, shower floors, kitchen counter tops and braai area counters just to give a few uses or examples of its versatility.
Ec0grind can be applied from 20 to 50mm and does not require a bonding medium such as acrylics or styrene butyl rubbers. It has a very low shrinkage, approximately 20% of standard concrete, if cured properly. The final finished material can be functional within 72 hours of laying it down.
According to Attwell, specifiers should turn to this product because the material is aesthetically pleasing while reducing the carbon footprint by as much as 97,5% of conventional concrete flooring. It is an economically and environmentally viable alternative to resin and standard exposed aggregate concrete floors.
