Argo Graphene Solutions reports results of the 56-day compressive strength test on its graphene-infused concrete mix poured in Tennessee

Argo Graphene Solutions has announced the results of the 56-day compressive strength test on its graphene-infused concrete mix poured in Bristol, Tennessee in October 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.
