Artigo IPEN-doc 21219 Assessing the pozzolanic activity of cements with added sugar cane straw ash by synchrotron X-ray diffraction and Rietveld analysis2015 - CALLIGARIS, GUILHERME A.; FRANCO, MARGARETH K.K.D.; ALDRIGE, LAURENCE P.; RODRIGUES, MICHELLE S.; BERALDO, ANTONIO L.; YOKAICHIYA, FABIANO; TURRILLAS, XAVIER; CARDOSO, LISANDRO P.Sugar and alcohol industries generate large amount of wastes that could produce ashes of great reactivity with pozzolan properties. The objective of this paper is to evaluate the pozzolanicity of Sugar Cane Straw Ashes (SCSA), thermal treated, at different curing times. Employing Synchrotron X-ray radiation for XRD measurements, scans from 10 to 110 (h 2h setup) allowed the quantification of several phases of the cement pasts through Rietveld analysis. The SCSA substitution of 20% (weight) in Ordinary Portland Cement (OPC) has improved the AFt (Ettringite) formation up to 47% for 90 days curing time. The Portlandite concentration analysis allowed concluding that this addition of SCSA in OPC has caused a delay in the cement setting time. Moreover, the behaviour of the C3S and Calcite contents in both OPC and OPC/SCSA samples were determined by refinement of the XRD pattern using the Rietveld method.Resumo IPEN-doc 02784 Simetria em diagramas de difracao multipla1995 - PARENTE, C.B.R.; MAZZOCCHI, V.L.; SASAKI, J.M.; CARDOSO, L.P.Resumo IPEN-doc 02782 Simetria em diagramas de difracao multipla1995 - PARENTE, C.B.R.; MAZZOCCHI, V.L.; SASAKI, J.M.; CARDOSO, L.P.Resumo IPEN-doc 05671 Obtencao de precipitados de magnetita sob um campo de ferrofluido Fesub(3)Osub(4)-Dsub(2)O1994 - PARENTE, C.B.R.; RODRIGUES, K.C.; MAZZOCCHI, V.L.; ROCCATTO, A.; GAMA, S.; CARDOSO, L.P.Resumo IPEN-doc 05670 Simetria nos diagramas de difracao multipla1994 - PARENTE, C.B.R.; MAZZOCCHI, V.L.; ASAKI, J.M.; CARDOSO, L.P.Resumo IPEN-doc 05468 Caracterizacao cristalina e magnetica de precipitados de magnetita obtidos na preparacao de ferrofluido Fesub(3)Osub (4)+Dsub(2)O1994 - RODRIGUES, K.C.; PARENTE, C.B.R.; MAZZOCCHI, V.L.; ROCCATTO, A.; GAMA, S.; CARDOSO, L.P.Resumo IPEN-doc 04791 Estudo do tamanho de grao de particulas de magnetita obtida na preparacao do ferrofluido Fesub(3)Osub(4) + Dsub(2)O1993 - RODRIGUES, K.C.; PARENTE, C.B.R.; MAZZOCCHI, V.L.; ROCCATTO, A.; GAMA, S.; CARDOSO, L.P.Resumo IPEN-doc 04344 Analise por tecnicas de difracao de neutrons e de raios-x de precipitados de magnetita obtidos na preparacao do ferrofluido Fesub(3)Osub(4) + Dsub(2)O1992 - RODRIGUES, K.C.; PARENTE, C.B.R.; MAZZOCCHI, V.L.; ROCCATTO, A.; GAMA, S.; CARDOSO, L.P.Resumo IPEN-doc 03327 Simulacao de difracao multipla de raios-X1989 - COSTA, C.A.B.S.; CARDOSO, L.P.; MAZZOCCHI, V.L.; PARENTE, C.B.R.Artigo IPEN-doc 13874 Influence of austenite grain size on mechanical properties of stainless SMA2002 - OTUBO, JORGE; NASCIMENTO, FABIANA C.; MEI, PAULO R.; CARDOSO, LISANDRO P.; KAUFMAN, MICHEL J.
