- Abstract
- In the work, on specific examples of various cement-concrete mixtures, the interaction of local portland cements with various types of nanomaterials was studied. It has been established that the change in the strength characteristics of concrete, as well as the change in the specific surface area of cement particles in water-cement systems, depending on the content of nanomaterials, has a similar and predominantly wavy nature, the form of which differs for different cement-nanomaterial pairs. The optimal concentration ranges of nanomaterials in the range of their low values have been established, which provide an increase in the strength of the final products by 18-40 %. The possibility of accelerated preliminary determination of these optimal ranges of nanomaterials using cement particle size distribution analyzers in aqueous suspensions and suspensions in isopropyl alcohol is shown.
