ASTM Class C Fly Ash

NMC markets fly ash from several different, high volume source locations in Minnesota, Iowa and Wisconsin.  We provide 100% beneficial re-use of the annual production for all of our Utility partners through dedicated storage and trucking.   

In addition to having pozzolanic chemistry, and being a recycled coal combustion by-product, Class C fly ash improves the strength, workability and durability of concrete.
