“…However, compared with the control treatment (tap water without zeolite content), the reduction of compressive strength of concrete affected by the simultaneous use of zeolite up to 20 % with tap water or briny groundwater was not greater than 10 %. Similarly, it was reported that substituting cement by zeolite up to 20 % did not cause the reduction of compressive strength of concrete [19,24] which is closely in accordance with the results of present study. Since there is little data about the simultaneous effects of using unconventional water and zeolite percentage on the compressive strength of concrete, it is necessary to conduct similar studies to achieve a proper conclusion in this subject.…”

“…These results in more filled voids and improve the concrete microstructure and finally increase the compressive strength of concrete [12,19,[21][22][23]. However, the use of natural zeolite in the concrete mix design has more advantages including reduction of air pollution to carbon dioxide due to decreasing the cement consumption [2, 14,21,24] and molecular sieving property and high cation exchange capacity of natural zeolite which can efficiently adsorb different contaminants in the concrete mix design and mitigate the adverse effects of these substances on the concrete [25]. For instance, the results of a study showed that the use of zeolite in concrete mix design resulted in a positive effect on the concrete resistance against some corrosive salts [26].…”

The present study was conducted to investigating interaction of three types of mixing water (tap water, briny groundwater and a mixture of their equal ratio), four levels of cement substitution with zeolite in the concrete mix design (0 %, 10 %, 20 % and 30 %), two levels of cement content (250 and 350 kg·m−3) and seven curing ages (3, 7, 28, 56, 90, 180 and 365 days) on compressive strength of concrete. In order to statistical analysis of data - a means that was not employed in the similar studies - the study was designed as a factorial experiment based on the completely randomized design with 168 treatments and three replications (totally 504 concrete specimens). The results of the analysis of variance (ANOVA) showed that neither of the two-, three- and four-way interactions of curing age with other factors were not statistically significant. This means that the gain rate of compressive strength of concrete by time was significantly similar in each possible combination of cement content, water type, and zeolite percentage. However, regarding the significant two- and three-way interactions of other studied factors, more attention should be paid to the results of these interactions than the simple effects of factors. Accordingly, based on the means comparison test (least significant difference: LSD), simultaneous use of unconventional waters with zeolite up to 20 % in the cement content 350 kg·m−3 can be recommended in terms of compressive strength of concrete.

“…Khoshroo et al studied the effect of micro‐nano bubble of water, zeolite and chekneh pozzolan on mechanical and durability properties of concrete using superpliztezer Their results showed that nano bubble of water improved mechanical and durability properties of concrete samples. In contrast, in our study we made concrete samples with a mixture of zeolite and meta‐kaolin and used micro nano bubble of water instead of drinking water and tested the mechanical and durability of concrete samples.…”

“…We demonstrated that concrete samples using both zeolite and metkaolin and micro nano bubble had a higher mechanical strength and durability properties in comparison to concrete samples containing zeolite and meta‐kaolin and drinking water. Finally, while Khoshroo et al used checkneh pozzolan in their study, we used meta‐kaolin in ours.…”

This research investigates the effect of using pozzolans as a substitution for a part of cement in concrete sample production, and using micro‐nano bubbles of water as a replacement for water in the mixture of concrete samples. We also sought to determine the optimal combination of zeolite and meta‐kaolin mixed with micro‐nano bubbles of water on the mechanical and durability properties of concrete samples. The results of the experiments indicate that using 10% zeolite in the concrete samples increased compressive strength and flexural strength by 3.7 and 17.85%, respectively. It also decreased 30 min water absorption, 24 hr water absorption and chloride permeability by 4.34, 16.61, and 41.52%, respectively, at the age of 28 days compared to the control sample. In addition, samples containing micro‐nano bubbles of water with 50 and 100% replacement for water in mixed concrete increased the compressive strength by 8.82 and 13.2%, increased the tensile strength by 10 and 19.64%, and decreased 24‐hr water absorption by 14.13 and 18.96% at the age of 28 days compared to the control samples. The best outcomes were achieved with a combination of 10% zeolite, and 10% meta‐kaolin mixed with 100% micro‐nano bubbles of water, which increased compressive strength, tensile strength and flexural strength by 14.85, 18.37, and 5.92%, respectively, compared to the control sample. Moreover, it decreased 24‐hr water absorption and chloride penetration at the age of 90 days by 17.56 and 80.45%, respectively, as compared to the control sample.

The effect of using water containing micro‐nano bubbles (WMNB) without adding any admixtures and normal water (NW) on the mechanical properties of cement mortar and concrete samples were investigated. Four various water to cement ratios equal to 0.6, 0.5, 0.4, and 0.35 (ranging from conventional concrete to high strength concrete), and three different curing ages of 7, 28, and 90 days were considered. The experimental results showed that the initial and final setting time of cement paste, the flow of hydraulic cement mortar and the slump of concrete samples made with WMNB were lower than that of made with NW. However, the compressive strength of cement mortar in using WMNB indicated an increase up to 16 and 7% in at 7 and 28 days, respectively. We also concluded that the optimum percentage of water to cement ratio was 0.35, which in that ratio the compressive strength enhancement of concrete made of WMNB reached the peak of 6, 18.3, and 16.3% at 7, 28, and 90 days age, respectively. Whereas increasing water to cement ratio, resulted in reducing the compressive strength of concrete. Besides, the high‐resolution scanning electron microscopy images with Energy Dispersive X‐Ray analysis were briefly conducted to explore the morphological change.
