Expanded CHRYSO Quad Portfolio Admixture and Services

Chryso combines water-reducing admixtures with a set of services and tools provided through their local technical services team and network of regional application labs. These services evaluate the quality of natural and manufactured sands looking at sand gradation, shapes, and swelling clay pollution. This unique combination of solutions optimizes production costs, while improving the quality and performance of concrete using challenging sands. 

“Depleting resources has made sourcing good quality sand difficult. As the quality of sand significantly impacts concrete performance, it has become a major challenge for the concrete industry,” said Chryso North America President Steve Williams. “In response to the challenges of the circular economy, we are pleased to deliver the expanded CHRYSO Quad portfolio, combined with our local technical expertise, to our North American customer base. The innovative product offerings enable the use of lower quality, locally sourced or manufactured sands without compromising concrete quality, while improving the concrete CO₂ footprint. CHRYSO Quad is another solution from our diverse product portfolios to assist the industry in achieving technical, business, and sustainable objectives.”

Tailored Regional Approach

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.ChrysoThe North American team works with each customer to identify the best admixture for their local sand source. It starts with the analysis of sands using the patented CHRYSO CLEAR Test method, which diagnoses the presence and portion of swelling clay. Then, sand gradation is measured and integrated as a factor of the concrete mix design optimization. CHRYSO Quad admixtures significantly compensate for the loss of rheology, flowability and finishability of fresh concrete, providing ease of application, replacing up to 100% of natural sands by manufactured sands.

Characterize the type and quantity of clay embedded in your sands with ChrysoClear Test. Unique characterization method for swelling clay which is a real alternative to the methylene blue test with higher accuracy and reproducibility, and very easy-to-use testing in the lab.ChrysoThis allows clients to gain flexibility by integrating new sands into their concrete mix and overcome shortages or tensions in material supplies. The use of local resources also contributes to reducing supply costs and decreasing the carbon footprint associated with the transportation of raw materials.

An additional benefit is that CLARENA MC 2000, another clay mitigation technology, reinforces the offering, providing concrete producers with the largest solution offering for challenging aggregates in North America.

For example, an evaluation of reference concrete mix design and the manufactured sand was performed for a customer that wanted to optimize their mix to reduce embodied carbon by using locally available manufactured sand. CHRYSO Quad 855 EMx was then proposed as the solution to optimize the mix design. As a result, the customer solved the material availability issues, reduced costs, and reduced their concrete embodied carbon by 5 percent by replacing 50 percent of their natural sand with locally available manufactured sand, avoiding long-distance transportation.
