Due to the high demand for cement, the production of high-quality cement is considered important. In our studies, the use of
activated microsilica and a new polycarboxylate superplasticizer to reduce cement consumption and increase its strength gave
effective results. The compressive strength of samples of ordinary cement and cement with the addition of activated microsilica
was studied. The solidification times of the obtained samples were also studied and compared by X-ray diffractometry. In the
results obtained, it was found that the compressive strength of a sample of a cement composite with 10% activated microsilica is
higher than that of a sample of traditional cement.
