Looking back 35 years to his job in Northern Virginia as an American Concrete Institute testing technician responsible for the quality of concrete delivered to building jobsites, civil engineer Rick Bohan recalls that concrete was called “mud.”
“Contractors would ask, ‘When is the mud arriving?’” says Bohan, senior vice president of sustainability for the Portland Cement Association (PCA). “It wasn’t in a pejorative way,” he adds. “Concrete was just another cost item, with no more value than anything else on the jobsite,” he explains.
