The Lehigh Cement Co. plant in Leeds, Ala., celebrated in October the commissioning of its 20,000-metric ton, state-of-the-art, multi-compartment, environmentally friendly silo. The festivities began with presentations by company management about the construction and unique features of the silo.
The new “D” Silo features highly-sophisticated environmental controls to produce a virtually dust-free product loading system. The facility, which took about two and a half years to construct, is 79 feet in diameter and 239 feet tall, and more than 6,200 cu yd of concrete was used during construction. The concrete mix included the plant’s own Type C1157HE cement and a ground granulated blast furnace slag cement, which yielded an end product with a lower carbon footprint and an expected service life of 100 years.
