Vancouver, British Columbia--(Newsfile Corp. - July 13, 2026) - Argo Graphene Solutions Corp. (CSE: ARGO) (OTCQB: ARLSF) (FSE: 94Y) ("Argo" or the "Company") is pleased to announce encouraging initial performance results from its graphene oxide cement additive program utilizing graphene produced through the proprietary STREAM™ graphene production platform licensed exclusively from Grapherry, Inc. The Company also announces that it has become a member of the Advanced Carbons Council, further strengthening Argo's participation within the global advanced carbon materials industry.
These developments represent important milestones as Argo continues executing its strategy of commercializing proprietary graphene technologies across multiple high-growth industrial markets.
Initial Commercial Validation of STREAM™ Technology
The graphene oxide ("GO") used in the testing was manufactured utilizing Grapherry's proprietary STREAM-G™ and STREAM-O™ production processes, directly linking the performance results to the proprietary technology platform that now forms the foundation of Argo's long-term graphene commercialization strategy under its previously announced exclusive worldwide licence agreement.
Initial testing demonstrated that the addition of only 0.05 wt.% graphene oxide, equivalent to approximately five parts graphene oxide per 10,000 parts cement by weight, increased ultimate compressive strength by approximately 60% compared to control samples.
Testing was performed using ASTM-standard 2-inch by 2-inch cement specimens cured for seven days prior to compression testing. Importantly, the results were reproduced consistently across multiple independent test batches, providing encouraging early validation of the technology's performance.
Graphene oxide functions as a nano-additive within cementitious materials by improving cement hydration, refining pore structure, reducing microcracking, and enhancing load transfer throughout the cement matrix. These improvements can be achieved using extremely low additive concentrations, making graphene oxide an attractive candidate for commercial-scale construction applications.
Management believes these initial results represent an important milestone in demonstrating that graphene produced using the proprietary STREAM™ platform can deliver meaningful and reproducible performance improvements under commercially relevant testing conditions.
While seven-day compressive strength testing provides valuable early performance data, the Company notes that 28-day compressive strength testing is the industry benchmark for structural concrete applications. Argo intends to continue its testing program and believes future 28-day results will provide additional validation as commercialization efforts continue.
