Abstract: The Rice Husk Ash (RHA) was obtained by incinerating Rice Husk with a temperature of 300℃, 500℃, 700℃, and then added into control mortars as replacement of cement to prepare modified mortars. The microstructure of RHA was characterized by FT-IR test, then the corrosion and carbonation resistance of mortars were investigated. Additionally, the microstructure of cement mortars was revealed using the SEM test. Researched results indicated that the cement hydration is improved and the mezzanine structure of RHA at 700℃ is compact, while the mezzanine of RHA at 300℃ is composed of crisscross plates. Moreover, the incorporation of RHA improves the corrosion and carbonation resistance of mortars.
