Properties of zeolitic tuff (clinoptilolite) blended portland cement

摘要

The aim of this study is to examine physical, chemical, mechanical and microstructural properties of mortars produced by blending clinoptilolite, which is a zeolite mineral abundantly found in nature, into Portland cement with increasing ratios. It was observed that plasticity times extend depending on the blend ratios of clinoptilolite blended cements and that early strengths change according to Blaine values. It was also determined that the final strengths develop in proportion to reactive SiO_2 and ion exchange capacity of clinoptilolite depending on the CH level in the medium.
