CHRYSO®Quad Admixtures for Complex Aggregates for Circular Economy and Sustainable Concrete Home Concrete Sustainable Concrete Solutions Complex Aggregates (Circular Economy) Quad® Optimising Local and Recovered Aggregates for High-Performance, Sustainable Concrete The CHRYSO®Quad range promotes a circular economy approach by enabling the use of locally sourced or recycled aggregates in concrete production without compromising technical performance. By integrating complex sands and materials recovered from demolition sites, CHRYSO®Quad helps concrete producers optimise local resources, reduce supply costs, and lower the carbon footprint of construction projects. With CHRYSO®Quad, concrete manufacturers can maintain workability, rheology, and productivity while accommodating a wider variety of aggregate types, including those with varying fines, sand shapes, and swelling clays. Paired with innovative tools such as CHRYSO®Clear Test and the CHRYSO®Quad Lab App, the range ensures concrete producers can quickly identify the most suitable admixture solutions for their specific materials, supporting consistent quality and sustainable outcomes. Circular Economy Optimised Performance Advanced Testing Cost & Resource Efficiency Complex Aggregates: Impact on Concrete Performance and Workability Lack of Fines Reduces compactness → increases porosity Affects rheology → can cause bleeding and pumpability issues Excess Fines Raises water and admixture demand Challenges rheology → reduces pumpability and workability Increases mixing time → impacts productivity Sand Shape Influences water and admixture requirements Affects rheology, workability, and retention Can increase mixing time → impacts productivity Swelling Clays Raises water and admixture demand Impacts rheology and workability retention Can increase mixing time → affects productivity Resources & Support Analysis of your sands With CHRYSO®Clear Test, a unique, patented tool developed by Chryso, we can quickly detect the presence of swelling clays in sands. The test can be conducted either on-site or in a laboratory, providing immediate and precise results. CHRYSO®Quad App Chryso has developed the CHRYSO®Quad Lab App, a new application designed to analyze alternative supply sources near your concrete production site and identify the most suitable admixture solution. Step Into the Sustainable Loop of the Circular Economy Discover how adopting a circular economy approach — using locally sourced or recycled aggregates from deconstruction projects — can transform your concrete production and advance sustainable construction. Watch the video to see how the CHRYSO®Quad range and our expert services help optimise production costs while maintaining high-quality, high-performance concrete even when working with complex aggregates. Click here to learn more Products Complex Aggregates (Circular Economy) Quad® 890 A mid range water reducing plasticiser featuring Quad® CLEAR Technology, designed to improve performance with contaminated aggregates and manufactured sands. Complex Aggregates (Circular Economy) Chryso®Quad 930 Chryso®Quad 930 is a new generation high-range water reducing superplasticiser incorporating Chryso innovative CLEAR Technology. This admixture results from our expertise in hybrid polymer technology using our most recent knowledge of the synthesis of molecules. Chryso®Quad 930 has been specifically formulated to be used effectively in mixes containing clay and silt contaminated aggregates, and also finely graded aggregate leading to cement reductions. This can also open opportunities for previously unusable materials. Chryso®Quad 930 can be used to produce high workability concretes without additional increase in mix water content. It can be used in a great range of concretes, including low water cement ratio mixes, or to allow an increase in slump class without requiring additional cement. Complex Aggregates (Circular Economy) Quad® 909 Quad® 909 is a new‑generation mid‑range water‑reducing plasticiser incorporating advanced Quad® CLEAR Technology. Developed through hybrid polymer technology and the latest molecular synthesis expertise, Quad® 909 provides enhanced consistence retention and reliable performance. It is specifically formulated for mixes containing aggregates contaminated with high levels of clay or silt, manufactured sands, and crushed fines, helping reduce cement demand while maintaining performance. Quad® 909 also remains robust against variations in cement chemistry, ensuring consistent behaviour across diverse materials. Quad® 909 offers a wide dosage range and supports a broad spectrum of concretes, including low W/C ratio mixes, high workability mixes, and mixes requiring slump class increases without additional water or cement.
