DESCRIPTION:Speakers: Estela Garcez (Monash University)\nThe degree of hyd
 ration of cement pastes is critical for determining properties such as the
  durability of concrete. As part of an integrated study on the prediction 
 of chloride ingress in reinforced concrete\, synchrotron X-ray powder diff
 raction was used to estimate the degree of hydration of cement pastes. Whi
 le for the past 20 years the composition of Portland cement has been deter
 mined by Rietveld analysis of X-ray diffraction\, nevertheless there are a
  number of factors\, including the amorphous content of the cement and rel
 ative proportion of mineral polymorphs present in the initial clinker\, wh
 ose impact on the analysis are still not completely understood. X-ray powd
 er diffraction beamlines from The Brazilian Synchrotron Light Laboratory (
 LNLS) and The Australian Synchrotron were used to analyze a suite of produ
 ction cements from both countries. The results showed significant differen
 ces in degree of hydration and composition in the two cements.\n\nhttps://
