TLDR
In this article, two techniques are discussed to measure the colour of concrete samples after fire exposure, namely a spectrophotometer and a calibrated flatbed scanner, which are used to trace the temperature history of the concrete, from which the corresponding fire damage can be assessed.About:

Evaluation of pore structures and cracking in cement paste exposed to elevated temperatures by X-ray computed tomography
TL;DR: In this paper, a series of increasing temperatures was used to explore the temperature-dependent evolution of internal pore structure and fracture networks in a cement-based material by fire, based on visual observations of the 3D internal structures revealed by X-ray CT.

Revealing the temperature history in concrete after fire exposure by microscopic analysis
Emmanuel Annerel,Luc Taerwe +1 more
TL;DR: In this paper, three methods for determining the maximum temperature to which a concrete structure was submitted during a fire are studied, including the physico-chemical transformations of heated concrete with scanning electron microscopy (SEM), features visible under the polarising and fluorescent microscope (PFM), and the influence of heat on the color of the aggregates.
