World Cement,
According to Chryso, the quality and availability of the aggregates used for concrete – and especially sand – is a major challenge for the construction industry, particularly quarry companies and ready-mixed concrete professionals. The new Chryso®Quad admixture solutions provide an answer to use challenging sands, including low or high fines content, swelling clay, and shape factors. Chryso Quad is a specific comprehensive range of products and services for producing concrete matching the required performance criteria.
The solutions are able to enhance the quality of concrete that features challenging sands, but also promotes sustainable development and reduces costs by sourcing resources from local suppliers, streamlining the procurement process and lowering the carbon footprint.
Based on 10 years of R&D that focused on developing special polymers, CLEAR® (Clay Enabling Admixture Response) and GRAFT (Gap GRAdation Fixing Technology) technologies are also part of the Chyrso Quad range. CLEAR technology specifically targets an excess of fines and swelling clay problematics, by helping to disperse the binders and reduce viscosity. GRAFT technology addresses the issue of low fines content and specific shape factors, while improving concrete cohesiveness and finishing.
Services
Chryso also offers services, including the Chryso Quad Lab diagnostics tool for reliably and quickly characterising sand, based on three criteria (fineness modulus, type of sand, and absorption).
The company has also built on its expertise by launching and patenting the new in-situ Chryso CLEAR Test for quantifying the swelling clay content. After field testing and analysing the sand, Chryso’s technical experts provide a tailor-made Chryso Quad admixture solution, which can be tailored to reflect changes in available resources.
Environmental considerations and cost
Reducing the environmental impact is a major challenge faced by concrete manufacturers and quarry companies. Implementing an extended range of sands and incorporating challenging sands is consistent with an eco-friendly approach to concrete design. It improves the use of local resources, optimises procurement costs, and lowers CO2 emissions. The Chryso Quad solution fosters the circular economy and offers a response to economic and environmental needs.
