CHRYSO®Quad
Leverage lower quality sands to produce great concrete
Lower quality sands: Impact concrete performance and placement
Scarcity of good quality sands and the impact of transport on concrete embodied carbon, is providing significant challenges to the industry. However, the quality of sands has a direct impact on concrete performance, placeability and finishability.
The possibility of using lower quality sands, which are locally sourced, without compromising the concrete quality significantly contributes to reducing supply lead time, costs and improving the concrete CO2 footprint.
CHRYSO®Quad is a unique solution for extending the use of complex aggregates while maintaining superior concrete quality:
- Harsh manufactured sands (specific shapes)
- Sands with lower gradation (lack or excess of fines)
- Swelling clay contaminated aggregates

CHRYSO®Quad solutions
CHRYSO®Quad is a unique solution that combines water reducing admixtures with a set of services to evaluate the quality of sands and adjust the concrete mix design, to achieve equal or better performance cost-effectively.
Full product offering based on proprietary polycarboxylate technologies that are highly efficient for mitigating clay-related water demand issues and lack of the concrete cohesiveness and flowability due to specific gradation/shape aggregates.
Characterize the type and quantity of clay embeded in your sands with CHRYSO®Clear Test.
Unique characterization method for swelling clay which is a real alternative to the methylene blue test with higher accuracy and reproductibility, and very easy-to-use testing in the lab and on site.
We support our customers with mix design proportioning considering your sand gradation, shape and other materials.
Enter the circular economy and its virtuous circle
The implementation of a circular economy approach with the use of local aggregates or aggregates from deconstruction sites is a major challenge to accelerate sustainable construction.
The CHRYSO®Quad range and dedicated services optimise production costs, while improving the quality and performance of concrete using complex aggregates.
