OPF90

OPF90OPF90, LA Ash's CFB bed ash brand is a product from coke combustion. OPF90 (commonly known as bed ash) is unmodified circulating fluidized bed combustion deposit. The OPF90's lime content, particle size and high surface area make the byproduct self-cementing when hydrated. OPF90's properties also allow OPF90 to be used for stabilizing silty/sandy soils for road base in lieu of hauling soils off site.
