Research of the influence of vibroactivated lime on the hydration of portland cement and its hardening

The influence of vibro-activated lime additive on the hydration processes of Portland cement and the nature of changes in the strength of cement stone at different stages of its hardening were studied. It was established that long-term storage of vibro-activated lime in a wet state does not weaken its properties as a modifying additive. The methods of determining the heat release of cement dough during hardening and X-ray phase analysis show that the addition of vibro- activated lime at the initial stages of hardening accelerates the physicochemical processes of hydration of calcium silicates of clinker minerals.
