This work presents a novel and cost-effective procedure that improves the reactivity of kaolinitic clay particles toward generation millimetric hard-core/zeolitized-shell units. The obtained particulate material is ready to use as ion exchanger beads in fixed adsorption bed. Starting from properly activated, millimeter-sized units, transition their external surface towards new crystalline order...

ABSTRACT Located in the southwest corner of Ratanakiri Volcanic Province, Wat Ocheng basalt is first known zeolite locality Cambodia. The a fine-grained, vesicular to amygdaloidal, subalkaline transitional alkaline intraplate tholeiite comprised 30% lath-like plagioclase (average: Ab51An45Or4), 35% interstitial augite Wo44En35Fs21), 25–30% zeolites after and volcanic glass, minor skeletal ulvös...

The effect of using trimethyladamantyl-ammonium hydroxide (TMAAOH) as a silica-modifying admixture to induce early-age mineralization during alkali-activation metakaolin was investigated and reported herein. In all material formulations, the use TMAAOH induced mineralization, increased mixture stiffening in fresh state, lowered total heat reaction. activating solutions with silica moduli above ...
