The paper considers alternative methods of activation of cement systems based on the use of internal properties of cement. Their peculiarity is the use of activated cement and changing the sequence of mixing of cement mortar. Mixing of the main volume of Portland cement with cement slurry and its prior curing for 15 minutes allowed increasing the strength characteristics of hardened cement paste. As shown by experimental studies, the strength of the samples increases by 10–30% depending on the method of preparation and curing time of the cement slurry. Further experiments will be aimed at researching “activated cement–activated water” system.
