Noorvand, Hassan and Abang Ali, Abang Abdullah and Demirboga, Ramazan and Farzadnia, Nima and Noorvand, Hossein (2013) Incorporation of nano TiO2 in black rice husk ash mortars. Construction and Building Materials, 47. pp. 1350-1361. ISSN 0950-0618


In this study, untreated black rice husk ash (BRHA) was employed as cement replacement in fractions of 10%, 20% and 30%. Dosages of 0.5%, 1.0% and 1.5% nano TiO2 were added into blended cement to study the mechanical properties and microstructural changes in mortars. The mechanical properties were studied using compressive and ultrasonic pulse velocity tests. XRD, SEM, TGA and DSC were conducted to investigate the chemical composition and microstructural changes of BRHA mortars with the presence of nano TiO2. The results showed that nano TiO2 in BRHA blended cement improved the mechanical properties and microstructure of BRHA mortars.
