“…The CaO/SiO 2 ratio of the zeolite used was under 0.5 (Table 1), which refers to its pozzolanic nature. It was in accordance with results from Ramezanianpour et al and others [17,36]. The amount of zeolite in total binder influenced the compressive strength, especially after two and three years of hardening.…”

“…The amount of zeolite proportionally affected the density; thus, the higher dosage of zeolite caused the lower concrete density. This is in contrast to some research [36,37], but, there, the zeolite content was up to 10%. According to Vejmelková et al [18], both the bulk and matrix densities of the cement-based composites decrease with increase in the zeolite supplementary.…”

This study is aimed at the utilization of natural zeolite as a prospective type of Supplementary Cementitious Material in connection with the innovations of construction solutions through the materials. The influence of zeolite on several properties of cement-based composites is studied. Basic characteristics of input powdery materials as well as the technological parameters of zeolite tested on mortar containing 50% of cement replacement are presented. The technical parameters of concrete containing 8, 13, and 25% of cement replacement by zeolite are presented as well. The paper is valuable due to the three-year testing period. The density of the hardened concrete was found to be decreasing with increasing zeolite content. While no significant differences in compressive strength were found after 28 days, differences between individual samples were clear after the long-term period. The presence of zeolite influenced the compressive strength positively in the case of the 8% and 13% replacement, while the higher proportion of natural zeolite (25%) caused lower compressive strength after 28 days but was similar to the reference concrete after three years. A major increase in strength was detected for all samples in the long-term period. It confirms the long-term potential of zeolite for strength improvement.

Volcanic originated pumice and zeolite aggregates have low density owing to their considerable porous structure. Porosity is usually correlated with insulation properties. In order to examine the effects of this lightweight aggregates on dead load of structure and insulation properties of standard construction materials, samples were produced by using pumice and zeolite at varying percentages by volume and control samples were manufactured with crushed sand. The samples were exposed to normal (standard) curing, hot water curing and steam curing to observe the effect of different curing regimes on their behavior. Bulk density and thermal conductivity tests were carried out on samples. Both bulk density and thermal conductivity values of the lightweight mortar samples were smaller than those of control sample. Besides, chemical compositions of aggregates and cement, analyses were also performed. Silica content of pumice and zeolite were %54,09 and %75,14 by mass respectively.

“…Nagrockiene [2] showed that the predicted freeze-thaw resistance calculations revealed 3.3 times higher resistance of concrete modified with up to 10% of natural zeolite. Uzal [3], investigated properties and hydration characteristics as well as paste microstructure of blended cements containing 55% by weight zeolitic tuff composed mainly of clinoptilolite mineral.…”

Abstractin this paper, to verify the effect of zeolite on the strength of concrete and the effect of high temperatures on this type of concrete 5 composition, containing different percentages zeolite (5%, 10%, 15% and 20%) with fixed water to cement ratio for perception of optimized percent of zeolite is made and influence of heat on compressive strength and ultrasonic speed waves was checked . according to tests, it is concluded that the replacement of 10% cement with zeolite at ratio water to cement 0.45 at ages 7, 28 and 90 days, is the optimized replacement level to zeolite.
