| Abstract Scope |
The rice beneficiation process annually produces tons of rice husk ash (RHA). In this work, RHA from companies in southern Brazil is characterized physically and chemically, seeking to apply them in cementitious materials. In addition, the waste was analyzed concerning the literature considering aspects related to its environmental characterization, generation data, recycling availability, and applicability in cementitious materials. The preliminary results of ash characterization demonstrate potential for use in cementitious materials. The ash has a high content of silica (amorphous) and crystalline phases, such as cristobalite. Regarding feasibility, maps of the generating companies and possible recipients of these residual materials in the study region confirm the proposed application. Using RHA in cementitious materials demonstrates an excellent alternative for sustainability and economic circularity in the study region. |
