audience of researchers and representatives from the construction industry, a Knife River-owned ready-mix cement truck poured a batch of concrete. By all appear-
ances the concrete looked similar to concrete poured at a construction site with one notable exception. This concrete had wood in it — more specifically cellulose nanocrystals (CNC). If this test batch of concrete yields the same strength and curing results in a real-world setting as has been found in the laboratory, CNC very
likely could be a gamechanger for the concrete industry. Jeffrey Youngblood, a professor of Materials Engineering at Purdue University whose research focuses on polymers, readily admits that Robert Moon, a materials research engineer with the U.S. Forest Service who was stasee CONCRETE page 74
