to interact and ensure the best result for not only the concrete supplier, but the client. He has peace of mind and only needs to deal with a single supplier.” Raubex Construction is currently busy with the Musina Ring Road project that diverts the N1 around the town of Musina in Limpopo for client South African National Roads Agency SOC Ltd (SANRAL). CHRYSO is supplying is CHRYSO ® Omega range of products and polypropylene fibres to this project, illustrating its fibre range as a solution to reduce the use of steel mesh in projects, at the same time reducing CO 2 emissions, cost and time. “These are all examples of our sustainable drive,” says Engelbrecht. With a focus on sustainable construction and new and innovative products, Engelbrecht says that its research facilities had to be improved. At head office, the Centre of Excellence performs testing and offers an advisory service to customers, engineers and architects in the South African sustainable construction industry. “An integral part of sustainable construction is end of life management – and for this we have various technologies and products that enable the effective recycling of aggregates. ▄ CHRYSO South Africa has the necessary certifications to support its drive in sustainable construction: • The ISO 14001 standard defines the standards of an efficient and environmentally friendly management system for the company. • The ISO 9001 standard establishes the requirements necessary for the setting up of a quality management system. • The ISO 450001 standard for Health & Safety.

simultaneously reducing their cementitious footprint.” Engelbrecht says there has not yet been an increased demand for heavy or wet precast products due to the general lack of infrastructure projects. “We have, however, launched several new product and technologies for wet precast producers in order for them to produce cost effective concrete with the new cementitious materials available.” It is evident that CHRYSO can assist the end-user to enable them to practise sustainable construction. Securing projects with its sustainability focus Engelbrecht says that 5% of CHRYSO’s global revenue is used for product development and innovation. “Our brand promise and slogan, ‘Innovation is our chemistry’ necessitates us to constantly innovate and as such we try to develop new technologies and products so that ranges are re-engineered and renewed every five years. This and the focus on sustainability have allowed us to secure a few projects locally,” says Engelbrecht. One is CHRYSO’s involvement in the recent construction of the 210 Mega litreconcrete reservoir at Vlakfontein. The size of the reservoir is such that it has been classified as a dam with a significant hazard rating, which requires stringent monitoring during the construction phase. “We supply PPC’s readymix division with five new product solutions that all, in different ways, make the production process easier, assist with the cohesion of aggregates in the mix and improves the overall concrete quality. Two key product solutions that are being supplied are CHRYSO ® Serenis, specifically designed to reduce concrete and mortar shrinkage at early and long-term ages; as well as 70 tons of CHRYSO ® CWA10 a crystalline waterproofing admixture for durable, water tight concrete. This is vital for water retaining structures,” says Engelbrecht. “All the products are designed
