Natural Zeolite Concrete K. Narasimhulu Abstract— Natural Zeolite is a pozzolana that occurs naturally. Its calcination leads to beneficiation in terms of the strength of concrete in which it is incorporated as a dmixture. In the present investigation permeability characteristics of concrete with calcined zeolite, natural zeolites were presented.

ABSTRACT: Natural adsorbent was optimized from four natural adsorption materials (kaolin, bentonite, diatomite, and natural zeolite) through the comparison of their ability to recover organic matter from an ultra-short-sludge-retention-time (ultra-short-SRT) activated sludge process effluent. Natural zeolite was modified by the loading of three types of chemical coagulants …
