The purpose of this article is to study the use of local waste based on mineral finely dispersed additives similar to substances that are formed as a result of cement hydration, which ensures high quality, increases frost resistance and forms a dense dissolved mixture. Reducing the consumption of a binder in mortar and concrete mixtures due to the introduction of modifying additives is also an important research field. The paper presents the results associated with pro-ducing a complex modifying additive consisting of waste products from marble and silicon di-oxide nanoparticles and its effect on the properties of cement systems. It is shown that the introduction of a modifying additive, while reducing cement consumption, can increase the compressive strength of cement paste up to 56 %. The X-ray phase analysis is used to determine the composition of the modified cement paste.
