"Natural zeolites are supposed to be an effective Supplementary Cementitious Materials due to its chemical composition and very fine microstructure. In this paper, selected mechanical, thermal and hygric, properties of several concrete mixes containing natural zeolite (clinoptilolite) as partial substitution of Portland cement are presented and compared with reference concrete. However, it is shown that although from both environmental and economical points of view it would be desirable to use highest possible amount of zeolite in concrete production, the extent of Portland cement replacement in concrete mixtures has certain limits. The studied zeolite with high clinoptilolite content is probably not a good choice for HPC concrete." . . . . .
