In recent years, fulleroid materials with a maximum particle size of several tens to several hundreds of nanometers, representing a special form of carbon and providing industrially significant effects when they are contained in the composition of raw mixtures in microdoses, have acquired special importance and exceptional interest for building materials science and technology. At the same time, there are nanomaterials capable of constituting a specific alternative to these substances. This article presents the results of experimental studies of the effect of nanofibrillar cellulose on the structure and properties of the cement composite. X-ray spectrometric analysis of nanofibrillated cellulose and microstructure of cellulose suspension was carried out. Tables and graphs of the effect of various concentrations of nanofibers on the rheological characteristics of the cement paste and the mechanical properties of cement stone are presented. Based on the results obtained, it is concluded that nanofibrillar cellulose is effective in improving the properties of cement paste and stone. Microstructural analysis revealed a positive effect of nanocellulose on the formation of the structure of the cement composite.
