The present study investigated the behavior of magnesium oxychloride cements when immersed in water using a combination of short wave infrared macroscopic imaging in the wavelength range 943 - 1643 nm and chemometrics. The effect of adding Phosphoric acid on subsequent water uptake was studied by obtaining sequential time series SWIR images and these were subjected to analysis by partial least squares discriminant analysis to identify regions of water uptake. The time series data indicates that water uptake was slower in cements containing phosphoric acid.

Abstract
The present study investigated the behavior of magnesium oxychloride cements when immersed in water using a combination of short wave infrared macroscopic imaging in the wavelength range 943 - 1643 nm and chemometrics. The effect of adding Phosphoric acid on subsequent water uptake was studied by obtaining sequential time series SWIR images and these were subjected to analysis by partial least squares discriminant analysis to identify regions of water uptake. The time series data indicates that water uptake was slower in cements containing phosphoric acid.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
