Expert fire-technical studies construction materials of the buildings in the establishment of the fire

Thermal analysis methods are aimed at fixing the physico-chemical properties of the substance in the process of temperature effects and is based on measurement of thermal effects and determining the change in mass that occurs when the chemical and physical transformations under the influence of heat in chemical compounds or between chemical compounds. By the method of thermal analysis study of the properties of cement stone after heat exposure. Samples of cement were annealed in order at temperatures from 200 °C to 1000 °C. The studies were obtained thermogravimetric curves (TG) and the results of differential scanning calorimetry (DSC). Set the regularity of the properties of the cement stone, which allows to differentiate the degree and duration of the thermal exposure of the samples
