摘要: This paper presents a production method for high reactive rice husk ash (RHA) by means of an uncontrolled combustion process. The process and pozzolanic activity RHA are described. reactivity was determined Thermogravimetric Analysis (TGA). Additionally, mortars with different percentages (5%, 10% 15%) were prepared to verify their influence on mechanical strength. results show that can be used as alternative source silica fume (SF).
