“…This may be caused by the different lasers used in their studies. The 1064 nm laser was applied in the research of Bonen et al (1994), while Bensted (1976) to synthetic C 3 A and 840 to synthetic C 3 S, which agreed reasonably well with those obtained by Bensted (1976) and Conjeaud and Boyer (1980).…”

“…Consequently, this band may be due to the vibrations of both the sulphate groups in the gypsum and the silicate groups in theˇ-C 2 S. Finally, the band appearing at 1121 cm 1 is due to the vibrations of theˇ-C 2 S units, although it is not assigned as such in the literature. 4 The weak band at 1082 cm 1 is due to symmetrical C-O stretching in the carbonate groups present in calcium carbonate, existing in the sample.…”

The former were produced under standard oxidizing conditions, and the latter under reducing conditions.…”

The long-term hydration of white portland cement has been followed through micro-Raman spectroscopy, choosing for excitation the most adequate laser wavelength as deduced from a critical analysis of the previously reported Raman data. The bands of the corresponding spectra were attributed to the various anhydrous and hydrated phases, with full hydration of the anhydrous phases taking place after 180 days. Sulphoaluminates were seen to form in two different local environments, at 3 and 180 days respectively. Carbonates, as a secondary reaction product, were found in three different local environments.

Expanding the capabilities of Raman scattering as an analytical tool for engineering applications can optimize the technological output immensely. Understanding the homogeneity of any blended mix is one such significant parameter in the family of composite building construction materials that needs an appropriate tool for its measurement. Raman spectromicroscopy has been established here for the purpose of studying the chemical homogeneity at the microscopic scale of a dry binary blend used in the building constructions as an example. In this study, two waste stone powdered materials, obtained from western Indian stone fields, have been characterized in their respective unmixed forms using Raman spectroscopy up to an extent so that the same can be developed as a microscopic tool to clearly “see” the chemical homogeneity of a mixture. A step‐by‐step study has been carried out by first, simply making a physically separated and identifiable boundary of the two materials followed by obtaining a Raman line image. The Raman line map could clearly identify the boundary, which otherwise was not possible to appreciate visibly. The same recipe has been extended to study the homogeneity of a binary mixture (blended in 1:1 ratio), using a Raman area map. The novelty of the work lies in the advancement in the analytical tool's family to see the chemical homogeneity of building construction materials at the microscopic level. Chemical imaging using Raman spectroscopy has been demonstrated as a simple tool to understand the homogeneity of the dry binary blend, which was not possible by other simple techniques. Using Raman area mapping proves to be a quick, valuable, and effective tool for measuring the homogeneity of the blended mixes at the microscopic scale and important for application in building construction materials.
