LIME AND POZZOLAN BINDING CONTAINING ADDITIVES/SET ACCELERATORS FOR USE IN MORTARS

Searching for low environmental impact materials for use in mortars, lime-metakaolin binders can be a great alternative. However their long hardening process does not please this binder be used in current constructions. Little is known about its workability and setting time. Therefore, this work studied the rheological behavior and the influence of a setting accelerating agents in pastes containing limemetakaolin. The initial results showed that metakaolin contributed to lower yield strength in relation to the lime paste, but the setting time was still very long.
