Argo Graphene Solutions Reports 56-Day Compressive Strength Test Confirms 25% Total Increase in Graphene-Infused Concrete
Vancouver, British Columbia--(Newsfile Corp. - December 22, 2025) - Argo Graphene Solutions Corp. (CSE: ARGO) (OTCQB: ARLSF) (FSE: 94Y) ("Argo" or the "Company") is pleased to announce the results of the 56-day compressive strength test on its graphene-infused concrete mix poured in Bristol, Tennessee on October 17, 2025.
This follows the previously reported 28-day results announced on November 20, 2025. The test, conducted by Diversified Materials Testing LLC in Bristol, Tennessee, in accordance with ASTM C39 standards, involved cylinder samples from the initial pour of three on-grade slabs totaling 12.5 cubic meters (two 20-foot-by-30-foot slabs and one 15-foot-by-25-foot slab). The design mix targeted 4,000 psi compressive strength.
Key results:
- 7-day strength: 3,428 psi
- 28-day strength: 4,449 psi (11% increase over design)
- 56-day strength: 4,974 psi (24.35% increase over the 4000 PSI design. The Argo graphene additive mix consists solely of a graphene and water dilution design, "without" additional enhancing additives such as superplasticizers)
These results further validate Argo's proprietary graphene formulation, demonstrating continued strength gain over time and superior performance compared to standard concrete.
"The 56-day compressive strength results are encouraging to show our testing is running increased benefits without compromising existing known industry processes in construction for mixing, delivery, and installation etc. The 25% verification increase with no additional enhancing additives now creates a go forward performance baseline to effectively use "as is" or design any graphene-based additive for Argo Graphene cement, concrete products and asphalt.
"This confirms the long-term benefits and market integration of our graphene-enhanced concrete," said Scott Smale, Chief Executive Officer of Argo. "Our facility in Regina, Saskatchewan, will enable us to refine and scale this technology for broader market adoption."
The Company will continue project testing and development to advance commercialization in the construction industry.
