01/09/2010· Roadways have high potential for large volume use of HCFA. HCFA can be activated with lime kiln dust (a disposed residue of lime production plants) and used as the base layer for newly paved roads. Significant efforts have been made to use fly ashes in stabilization of highways base structures, unpaved roads and soil stabilization.
According to Chesner et al. (1998), both cemen t kiln dust (CKD) and lime kiln dust (LKD) can be used as activators in pozzolanic stabilized base mixtures. Depending on its reactivity, CKD may have potential for use as the sole cementitious material in stabilized base mixtures. Most research and construction with kiln dusts, however, has involved combinations of kiln dusts …
