Effects of Elevated Temperatures on the Properties of Portland Cement Mixtures Related to Surface Removal and Decontamination
From abstract: The effect of heat on the surface removal of concrete was studied by conducting brush tests on samples which had been subjected to prolonged high temperatures in an oven or in direct contact with an oxy-propane flame. Other methods of heat-treating surface layers of concrete were investigated by direct application of an oxy-aluminum torch on the surface and by the exothermic chemical reactions of pyrotechnic compositions placed directly on the surface.
