Products
LA Ash markets the CFB ash products (commonly known as fly ash and bed ash) that remain after combusting the petcoke and limestone in CFB steam generators under the names OPF70, OPF90, OPF42, OPF57 and OPF104.
 
LimestoneThese are only a few of the many processes for which CFB calcined limestone products can be used:
  • Reduce the plasticity index of clayey soil
  • Neutralize acidic waste
  • Stabilize hazardous compounds
  • Solidify sludge and saturated soils
  • A base course surfaces
  • In some cases, as an alternative to Portland cement for soil stabilization
Do not mix OPF products with any other chemicals or byproducts, including but not limited to Cement Kiln Dust (CKD), Portland cement or lime, due to certain chemical reactions and/or swell potentials. Questions should be directed to your sales representative.
