“…According to Davies (2005), NIR was discovered by William Herschel in 1800. With inputs from Ampere in 1835 and James Maxwell in 1864, the first NIR spectra were measured in 1881 by Abney and Festing.…”

“…Absorptions in the IR region are due to overtones and combinations of fundamental absorptions (occurring in the MIR spectral region) due to deviation in molecular vibration from the harmonic approximation (discussed shortly), which holds true only when almost all the molecules are in their vibrational ground state (fundamental vibration) in which the dominant spectral transition is the fundamental transition (Atkins and de Paula, 2002). This is because most absorption in the NIR region requires higher vibrational energy (Davies, 2005). At high vibrational excitation, the parabolic approximation tends to break down at some regions in the potential energy curve and the concomitant anharmonicity results in overtones and combinations of fundamental vibrations (Atkins and de Paula, 2002;Osborne et al, 1993;Pasquini, 2003).…”

“…The initial set back in the study of NIR spectra was partly attributed to the requirements of a knowledge of chemometrics, the computer, and use of very low-noise spectrometers; and the person who put all this together was Karl Norris (Davies, 2005). Chemometrics is the use of advanced statistics and mathematics in multivariate analysis (MVA) -calibration and classification.…”

Sustainable reuse of pre-treated drill cuttings (a hazardous waste) as part substitute for fine aggregate in concrete for construction purposes is becoming increasingly attractive; however, issues remain. With recent studies focusing on the use of near-infrared spectroscopic technique for non-invasive determination of chloride concentration in concrete structures, this review examines the applicability of this new technique in the rapid determination of other equally important physicochemical characteristics of concrete produced with this hazardous waste. The nature, source, composition, ecological effects of, and management options for drill cuttings are reviewed. Furthermore, the principles of near-infrared diffuse reflectance spectroscopy are highlighted and lessons from its practical applications in soil science and petrochemical, environmental, and civil engineering are discussed. A framework for a rapid near-infrared analysis of concrete produced with pre-treated drill cuttings for enhanced sustainability as a construction material is also proposed.

“…However, to develop these predictive models requires many samples, many hours of work and many computer calculations to develop a statistical model which can be used to predict future samples (Davies, 2005). The validity of the calibration models for future predictions depends on how well the calibration set represents the composition of new samples.…”
