Characterization, microstructure properties and impurities removal of treated rice husk ash (TRHA) as supplementary cementing material (SCM) in concrete using hydrochloric acid pretreatment process

Recently, the need towards production of environmental friendly and excellent performance cementitious material has been outlined properly. Based on extensive researches done since 1970s, it is proven that rice husk ash (RHA) is silica-rich material and hence categorized as pozzolans in concrete....
