​Argo Graphene Solutions reports graphene-enhanced concrete trial interim results 

Argo Graphene Solutions has announced the results of its ASTM 28-day compressive strength test on the recent test pour of Argo’s graphene-infused concrete mix in Bristol, Tennessee, which was initially announced in October 2025.

The test was carried out by Diversified Materials Testing, LLC, based in Bristol, TN, USA, and involved industry-standard compressive strength tests (on days 7, 21, and 28) on three concrete slabs totaling 12.5 cubic meters. The poured slab sizes included two 20-foot-by-30-foot slabs on grade and one 15-foot-by-25-foot slab on grade.
