摘要：
The authors have given results of investigations into the phase transformations of a cement material modified by a complex nanodisperse admixture that consists of a superplasticizer and nanoparticles (nanosilica sol and a carbon nanomaterial) by the method of thermogravimetric analysis; the method makes it possible to obtain quantitative information on the change in the mass of a specimen as a result of its heating. Thermogravimetry data have been compared with the results of ultrasound investigation and nanoindentation.
