Abstract
Geopolymers based on natural zeolite clinoptilolite were activated with different concentration of sodium aluminate and potassium hydroxide and the influence on compressive strength, density and water absorption were evaluated. The microstructure was analyzed by XRD, FTIR and SEM. The obtained geopolymers are comprised of newly formed zeolite phases – phillipsite, zeolite A.
