Data for: Deterioration of stone and concrete exposed to bird excreta – examination of the role of glyoxylic acid.

Materials throughout are identified as follows:

ls = limestone
ss = sandstone
pc = Portland cement
csa = calcium sulfoaluminate cement

Three types of data file are included:

X-ray diffraction traces, Sietronics CPI format, three types:
- original materials (identified with the material name)
- results of syntheses: 'ca glyoxy' and 'ca glyoxy basic'
- acid-degraded layers (identified as 'crust')
- sediments in tanks (identified as 'residue').

UV/VIS spectrometer traces, format: 1st column = wavelength, 2nd column = absorbancy
- acid solution: 'glyoxylic'
- exposure solutions after experiments: identified by material name.

CT scanner images, tiff format
- original materials, marked 'original'
- after acid attack, marked 'glyox'.
