30% stronger doesn't mean 30% less usage though so it would be interesting to see how much less concrete can actually be used in typical applications.

30% stronger might mean considerably more savings than 30% by weight, especially if the graphene concrete has better properties under tension (where concrete is abysmal). Stronger materials can have a larger volume to surface area ratio safely, picture an X shaped pillar rather than a full cylinder.

It depends a lot on situation. 30% stronger could mean even better than 30% less usage, when most of the weight of a structure is other concrete.
