Argo Graphene talks 56-day compressive strength test

Mr. Scott Smale reports ARGO GRAPHENE SOLUTIONS REPORTS 56-DAY COMPRESSIVE STRENGTH TEST CONFIRMS 25% TOTAL INCREASE IN GRAPHENE-INFUSED CONCRETE Argo Graphene Solutions Corp. has released the results of the 56-day compressive strength test on its graphene-infused concrete mix poured in Bristol, Tenn., on Oct. 17, 2025. This follows the previously reported 28-day results announced on Nov. 20, 2025. The test, conducted by Diversified Materials Testing LLC in Bristol, Tenn., in accordance with ASTM C39 standards, involved cylinder samples from the initial pour of three on-grade slabs totalling 12.5 cubic metres (two 20-foot-by-30-foot slabs and one 15-foot-by-25-foot slab). The design mix targeted 4,000-pound-per-square-inch compressive strength. Key results: Seven-day strength: 3,428 psi; 28-day strength: 4,449 psi (11-per-cent increase over design); 56-day strength: 4,974 psi (24.35-per-cent increase over the 4,000-pound-per-square-inch 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 with 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 et cetera. The 25-per-cent 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, Sask., 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. About Argo Graphene Solutions Corp.
