Abstract:

This work investigates the influence of various alkaline activators (Na and K) on

the properties of a Lebanese metakaolin-based geopolymer mortar. The first part of this

work consisted to find and treat a local Lebanese source of kaolin. The metakaolin was later

produced by the calcination of the local kaolin at a temperature reaching 700ËšC. Once

prepared the silica, alumina and alkali activator (either Na or K based) were mixed together

in order to obtain the required mortars. Results indicated that the sodium based geopolymer

mortars exhibit a greater compressive mechanical strength than the potassium based

mortars.

Keywords:

Geopolymers mortar, alkali mortar, Mechanical characteristics.
