Throughout 2021/22 New Zealand trials of what is said to be the world’s most promising material, graphene, took place using local materials. GtM Ltd has been working with NZ companies to understand how graphene interacts with local aggregates and whether the strength advantages that have been proven in the lab can be replicated in less controlled, industrial scale scenarios.

This compressive strength graph below shows a summary of 6 results from the control and graphene enhanced mixes. Graphene dosing and mix design were the same as the tensile tests. The test method may have had very small variations in size/weight of blocks (+/- 3%).
As you can see there is a material difference between the compressive strength of Graphene Enhanced to Control samples (263% better than Control). Like the tensile results the Graphene Enhanced samples also seem to be showing greater variation between tests.
