The possibility of obtaining cement mixtures on the basis of enriched waste products of neon–ferrous oxidised quartzes with high physio–mechanical characteristics has been established and the volume of optimum waste dosage of 30% has been determined. The radiographic analysis has shown that in the hydrated cement mixtures containing a quantity of 5 to 30% of waste with the inherent mineral elements in the hydrated cement, there is beta quartz and dicalcinate ferrite. It has been noted that with the waste increase in the cement mixtures the beta quartz content increases. When the microstructure of the hydrated cement mixtures with various dosages of waste was investigated, it was established that the porosity samples decrease with increase in the waste materials. The researched spectral microprobe analysis of the fine layers of the cement mixtures has shown the existence of calcium ferrite spots. It was determined that the waste particles which have been evenly distributed in the volume of cement mixtures are the centres of crystallisation of new growths that leads to increase cement stone durability.
