Argo Graphene Solutions Reports Graphene-Infused Concrete Test Improves Compressive Strength 11% over Design
Argo Graphene Solutions (OTCQB: ARLSF) reported ASTM 28-day compressive strength results from a Bristol, Tennessee concrete pour dated November 20, 2025. Independent testing on three slabs (total 12.5 cubic metres) by Diversified Materials Testing showed an 11% increase in 28-day compressive strength, equivalent to 4,449 psi versus a 4,000 psi design mix. The company said results align with prior tests by the University of Melbourne and Ceylon Graphene and noted its new Regina, Saskatchewan facility will support formulation improvements. A 56-day cylinder break test is pending and the company will update shareholders when available.
Argo Graphene Solutions (OTCQB: ARLSF) ha riportato i risultati della resistenza a compressione ASTM a 28 giorni da una betonatura eseguita a Bristol, Tennessee, il 20 novembre 2025. Test indipendenti su tre lastrici (totale 12,5 metri cubi) condotti da Diversified Materials Testing hanno mostrato un aumento dell'11% della resistenza a compressione a 28 giorni, equivalente a 4.449 psi rispetto a una miscela di progetto di 4.000 psi. L'azienda ha dichiarato che i risultati si allineano con i test precedenti dell'Università di Melbourne e di Ceylon Graphene e ha osservato che la sua nuova struttura a Regina, Saskatchewan, sosterrà miglioramenti nelle formulazioni. È in corso un test di rottura dei cilindri a 56 giorni; l'azienda informerà gli azionisti quando disponibili i dati.
