Dedicated services to characterize materials and adjust admixture solutions
It all starts with the analysis of sands using the patented CHRYSO®CLEAR Test method, which diagnoses the presence of swelling clay. Then, the dedicated CHRYSO®Quad Lab service allows CHRYSO experts to carry out a precise diagnosis of a series of additional parameters: particle size (to determine the lack or excess of fines), absorption, shape factors, etc.
Additionally, compaction tests are performed in CHRYSO's application laboratories to consider all the parameters of the concrete mix design. Finally, the brand-new digitalized service CHRYSO®Quad App proposes the most suitable admixture solution based on the customer's material characterization (sands and aggregates) and thus broadens the scope of potential supply sources.
The use of complex aggregates and sands while improving concrete performance
The customized CHRYSO®Quad admixture solutions are adjusted according to the available resources of complex sands and aggregates. This allows clients to gain flexibility by integrating new sands and aggregates into their concrete mix and overcome shortages or tensions in material supplies. CHRYSO experts accompany their clients in producing durable and robust concrete that can withstand material variations.
CHRYSO®Quad contributes to the circular economy and reduces the carbon footprint
By anticipating the constraints of quality and availability of local sands and aggregates, CHRYSO®Quad fully embraces a circular economy approach.
CHRYSO®Quad is a development lever for recycling materials from deconstruction, allowing for the recovery and use of recycled aggregates.
The use of local resources also contributes to reducing supply costs and decreasing the carbon footprint associated with the transportation of raw materials.
CHRYSO continues to deploy CHRYSO®Quad
To date, 9 million m3 of concrete have already benefited from CHRYSO®Quad solutions, including on large construction sites around the world. Leveraging its international network of application laboratories, CHRYSO provides answers to the sourcing challenges of aggregates faced by industry stakeholders.
CASE STUDY
With CHRYSO®Quad 870, a concrete industry player manages to use 100% of complex sands in its concrete formulation
To support a client in the south of France in optimizing the sand resources used in its concrete formulation, CHRYSO proposed its CHRYSO®Quad 870 solution, which improved productivity, concrete quality, and allowed for sourcing exclusively from local suppliers.
This industry player supplied his plant with sand from two quarries. A complex crushed sand, sourced from a quarry near the plant. A second "corrective" sand, from another quarry located 60km from the plant. Up to 50% of each sand was used in the different concrete mixes, which ranged from class S3 to S5.
In its specifications, the industry player requested that CHRYSO provides a solution to increase its capacity to use complex sands (with a high content of fines and the presence of clays). Thanks to the CHRYSO®Quad Lab service, sands were recovered and analyzed in the laboratory and in the plants. This allowed CHRYSO to design the customized CHRYSO®Quad 870 product. The first product testing phases were validated on site by sand variability checks carried out by the client using the CHRYSO®CLEAR Test kit.
As a result, the customer has extended the use of CHRYSO®Quad 870 to three other concrete plants and now uses 100% complex sand from a local quarry. The use of a single sand, with a constant dosage, brings a benefit of regularity in the production, reducing the weight of CEM II A cement in the design mix, which represents a 10% reduction of the carbon footprint. In addition, thanks to the exclusive use of short-distance sourcing, 24 lorry journeys per month have been avoided.

Ferring ADAPT-1 Trial Builds on Dosing Evidence for Follitropin Delta2.7.2025 11:00:00 EEST | Press release
Follitropin delta starting dose of 15 micrograms (µg)/day has comparable efficacy and safety as a starting dose of 225 International Units (IU)/day of follitropin alfa for ovarian stimulation in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) gonadotrophin-releasing hormone (GnRH) antagonist protocol cycles. This is the key finding of a trial presented today at the European Society of Human Reproduction and Embryology (ESHRE) Congress in Paris and published in Human Reproduction. These data build on previous studies which have established an estimated point of clinical correspondence for 10 µg follitropin delta to 150 IU follitropin alfa in this class of medications.1,2 The ADAPT-1 trial was a multicentre, randomised, assessor-blind study involving 300 women aged 18-40 years undergoing IVF or ICSI.3 The trial compared the efficacy and safety of follitropin delta and follitropin alfa using conventional dosing regimens with a primary endpoint of number of oocytes retrie
