Resumo
Sustainable development has been growing concern worldwide, with special emphasis to its effects on
climate change. An important action to reduce the environmental damage is the decrease of cement
use. In this study the pozzolanicity of Sugarcane Straw Ashes (SCSA), thermal treated, at different curing
times was investigated. Synchrotron X-ray Powder Diffraction measurements allowed the quantification
of several phases of the cement pasts through Rietveld analysis. The properties of cement paste are
directly related to the concentrations of Alite, Belite, Portlandite, Brownmilite and amorphous phases.
Tomography technique was also used to study the differences amongst the pore structures according
to type of ash used. The SCSA substitution of 20% (weight) in Ordinary Portland Cement (OPC) shows
to be a good option to recover the agroindustrial wastes.
