Determining the degree of thermal destruction of concrete made from cement production "Angarskcement" by IR spectroscopy

In the article the analysis of the IR spectra of concrete based cement M400 and MD, manufacturer «Angarskcement». The concrete had a different degree of thermal damage. It is established that differentiate the concrete is exposed to temperatures over 600 °C can be at the peak of portlandite (3640 cm -1) high intensity, low intensity, or absence, of a broad peak in the region of 3450 cm -1, characteristic of the OH groups of another nature.
