Abstract:
This study was aimed at evaluating an industrial production system of rice husk ash (RHA) with low carbon level. The system, developed in partnership with a local industry, consists of a continuously rotating furnace that can reduce the carbon level of residual RHA through re-burning. Different temperature bands, retention time in the furnace interior, and grinding degree were studied. The results indicate the feasibility of producing a material with reduced carbon levels, which is highly reactive and can be commercially used in the production of high performance concrete.
