Adsorption of 3‐monochloropropane‐1,2‐diol ester and glycidyl ester from refined bleached deodorized palm oil using zeolite‐based adsorbents

AbstractPalm oil processing can result in different food products like cooking oil and margarine. Nevertheless, these food products might contain harmful contaminants, namely 3‐monochloropropane‐1,2‐diol ester (3‐MCPDE) and glycidyl ester (GE), which can negatively affect animal organs and potentially cause human cancer. Therefore, the objective of this study was to lower the concentration of 3‐MCPDE and GE in refined, bleached, and deodorized palm oil (RBDPO) using zeolite as an adsorbent. Adsorption experiments were conducted in a batch reactor, varying the percentage of adsorbents, temperature, type of zeolite, and the use of a mixture of zeolite and activated carbon (AC). The sample was analyzed before and after adsorption using gas chromatography–mass spectroscopy (GC–MS) to confirm the concentration alteration of 3‐MCPDE and GE. The study showed that the most effective temperature for adsorption was 35°C and used a zeolite percentage of 2%. Beta zeolites resulted in the highest removal of 3‐MCPDE (86%) among the evaluated zeolites attributed to their elevated pore volume, Si/Al ratio, and overall acidity strength. Through a synergistic combination of beta zeolite and AC, the removal percentage of 3‐MCPDE was enhanced to 94%, with a corresponding 75% reduction in GE. This study paves the way for addressing 3‐MCPDE and GE concerns in RBDPO by combining zeolite and AC.

Characterization of traditional adobe with addition of zeolite regarding compressive strength

This work aimed to assess the compressive strength of traditional adobe and adobe by adding zeolite as a complement to clay to prolong the useful life of the clayey sedimentary deposits in the area and thus potentiate new zeolite deposits. The work began with elaborating test tubes with specific dimensions for traditional adobe and adobe with complementary percentages of zeolite in 25% and 50%. To assess the compressive strength of these elements, 12 test tubes from each of the groups were made, test tubes with approximate dimensions of 5x5x10 cm, and they were subjected to the respective test with the appropriate equipment. The results present values that must be considered and concluded with recommendations to help improve certain aspects of the studied elements.

Desain Dan Optimasi Proses Pirolisis Waste Oil Menggunakan Pendekatan RSM

The management of abundant oil waste in companies that are spread over tin mining operational locations is still not optimal. The waste oil comes from engine oil and hydraulic oil. With proper management, waste oil will become useful and have added value. This waste can be processed into HSD (High Speed ​​Diesel) fuel, so the company will get profit. The processing method used in waste treatment is the pyrolysis process. In this study, a pyrolysis tool was designed and built, and a test was carried out to obtain optimal parameters for the resulting fuel product using the Response Surface Methodology (RSM) method. The tests were carried out using activated Zeolite powder catalyst and 1000 ml of oil in each test. The indicators and parameters observed are the Quantity HSD and the percentage of Zeolite. The results of the optimization of the research process with the optimum formulation, namely setting temperature 285 oC, catalyst 109.8 gr, product yield 898.1 ml. Where as in the use of Raw Material Hydraulic Oil, the optimum formulation is a temperature of 325.8 oC, 118.6 gr catalyst, and a product yield of 920 ml with a duration of 60 minutes.

Analysis of intensification of zeolite drying on a vibrating conveyor dryer with infrared emitters

The object of the research is the drying process of zeolite. The work is dedicated to analyzing an effective method for intensifying the drying process of zeolite while preserving its structural integrity. For the given task, it was necessary to choose a promising drying method with minimized heat loss and preservation of the quality indicators of zeolite. Zeolite has a wide range of applications, including soil improvement, mineral fertilizer for plant growth, dietary supplement for animal feed, air, and water purification. The crucial process for obtaining high-quality natural zeolite is the drying process. In its natural state, zeolite contains moisture, and an excess of it can deteriorate its consumer properties. Therefore, considering the best and most efficient method of zeolite drying is a promising task today. There is no available data on drying zeolite using radiation methods in the literature. Typically, this material is dried in rotary dryers. However, this drying method often results in a significant percentage of zeolite being crushed into dust. Many industries require a granular structure for zeolite. With radiation drying, this drawback is absent or the percentage of crushed zeolite into dust is minimal. The main methods of drying zeolite have been examined, revealing a fact that indicates an incorrect approach to the drying process. Factors influencing the deterioration of zeolite's quality during drying have been analyzed. These factors have several drawbacks that affect the final product, namely: crushing zeolite into powder, over-drying, which affects its quality and poses a general scientific problem. The drawbacks of drying zeolite using the main methods have been identified. The authors have developed a dryer design that minimizes the deterioration of the mentioned qualitative characteristics of zeolite, addressing an important scientific and technical challenge of creating an efficient and environmentally friendly method of zeolite drying using infrared radiation energy and the development of appropriate equipment. The proposed dryer has suggested applications in various fields.

Evaluation of Resilient Modulus and Rutting for Warm Asphalt Mixtures: A Local Study in Iraq

Warm-Mix-Asphalt (WMA) allows aggregates to be coated with asphalt binder at a temperature lower than the Hot-Mix-Asphalt (HMA) temperatures by using additives that make the asphalt mixtures more workable and the asphalt binder viscosity reduced. Due to the cost and environmental advantages of WMA, it is now more frequently employed in the mixtures of asphalt pavement. WMA with two percentages of zeolite (0.3% and 0.5%) is used in this research. The optimum asphalt content of WMA mixtures has a lower value compared to the HMA mixture. According to Marshall Stability’s findings, the HMA has a higher value of stability, whereas the WMA mixtures for both percentages of zeolite have a lower value of stability. WMA mixture with 0.5% zeolite has a higher Marshall Flow value, which is followed by zeolite at 0.3% and the lower value of flow was for HMA. The resilient modulus for both HMA and WMA was determined. The findings indicate that, for the two percentages of zeolite, the resilience modulus of the WMA mixtures was lower than that of the HMA. Additionally, the findings indicate that the WMA has a high potential resistance against rutting that competes with the HMA mixture.

Low plasticity clay stabilized with cement and zeolite: An experimental and environmental impact study

To mitigate environmental issues caused by conventional binders and gain superior geotechnical properties, pozzolanic materials can be considered for soil stabilization purposes. Herein, the effectiveness of zeolite for enhanced treatment of cement-stabilized clay was studied by measuring pH, maximum dry unit weight (MDUW), optimum moisture content (OMC), unconfined compressive strength (UCS), and accumulated loss of mass (ALM), as well as carrying out scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. Then, the life cycle assessment (LCA) analyses were conducted to evaluate the potential environmental impacts of cement and zeolite production and their use as stabilizing agents in clayey soil. The soil was stabilized by 2, 4, 6, and 8% cement contents and 0, 15, 30, 45 and 60% cement replacements with zeolite. Furthermore, 56-day curing time was considered to assure accomplishment of hydration and pozzolanic reactions. Besides, samples were exposed to up to 8 wetting-drying cycles to evaluate durability-based parameters. The environmental impacts of the combination of cement, zeolite, and clay for constructing a one-kilometer pavement subgrade in terms of greenhouse gas (GHG) emissions and energy consumption in production, transportation, and execution were studied using LCA. Finally, Al2O3, SiO2, and CaO components were discussed to react with one another and to participate in the chemical reactions as the active composition (AC). UCS results indicated that up to 15% cement content replacement with zeolite, strength increased whereas it reduced thereafter. UCS and ALM were observed to decrease and increase during wetting-drying cycles, respectively. The efficacy of optimum zeolite percentage was more noticeable in higher cement percentages, both in terms of mechanical and durability tests. LCA confirmed that the efficiency of energy consumption and GHG emissions reduced with increasing zeolite. Also, for the samples containing zeolite and cement, the porosity parameter (n)/AC was nominated as a key controlling parameter for determining the UCS, ALM, consumed energy, and the produced CO2. Regarding the experimental program and LCA, the use of zeolite instead of cement is highly recommended both in terms of moisture changes, mechanical properties and environmental aspects.

Impact of Zeolite from Coal Fly Ash on Soil Hydrophysical Properties and Plant Growth

Zeolites can be extensively employed in agricultural activities because they improve soil properties such as infiltration rates, saturated hydraulic conductivity, water holding capacity, and cation exchange capacity. Natural and synthetic zeolites can efficiently hold water. Zeolites are also believed to have the ability to lose and gain water reversibly, without changing their crystal structure. In the present study, several laboratory tests were carried out using: (i) zeolite synthesized from coal fly ash (a waste product from burning coal in thermoelectric power plants), (ii) a silty loam soil, typically found in Southern Italy, and (iii) sunflower as a reference plant. The selected soil was amended with different percentages of zeolite (1, 2, 5, and 10%) and the effects of the synthetic mineral addition on the hydrophysical properties of the soil and plant growth were evaluated. The results indicated that soil–zeolite mixtures retained water more efficiently by pore radius modification. However, this causes a variation in the range of plant-available water towards higher soil humidity values, as the amount of added zeolite increases. These data confirm that zeolite addition modifies the selected hydrophysical properties of the soil with the effect of decreasing the soil drainage capacity, making the soil less habitable for plant growth.

Performance of Subbase Layer with Geogrid Reinforcement and Zeolite-Waterglass Stabilization

Some laterite soil is an inferior material for engineering applications such as road and highway pavement, dam construction and filling material. Laterite soil stabilization is required to increase its strength for field application purposes. The potential use of zeolite and waterglass as stabilizing agents is their pozzolanic properties. This study aims to analyze the strength and bearing capacity of laterite soil stabilized by waterglass-activated zeolite and reinforced with geogrid. The soil sample was prepared with a zeolite percentage of 4, 8, 12, 16 and 20%, and waterglass as much as 2, 4 and 6% with curing times of 0, 7, 14 and 28 days. Furthermore, the physical model test was carried out in the container with the optimum composition obtained from the compressive strength (UCS) and California bearing test (CBR) test. The stabilized subbase layer with geogrid reinforcement was placed on a subgrade layer with a substandard CBR value. The results showed that the compressive strength (UCS) of stabilized soil with a curing time of 7 days was found significantly increased. The CBR value also increased with the content of additive and curing time compared to the untreated soil. The physical model test results showed that the performance of stabilized laterite soil with additives and reinforced by geogrid (ZW-geogrid) as a subbase layer provides more optimal performance in carrying the load compared to the sand-gravel mixtures material.

Development of gypsum composite with enhanced mechanical and durable performance using chemical admixture and zeolite

This study deals with the properties of gypsum plaster that are synthesized by adding different proportions of zeolite used as mineral aggregate. The experimental tests also characterize the effect of superplasticizers to reduce the water by gypsum ratio of plaster and latex emulsion to improve the adherence between the gypsum surface and zeolite. The compressive, flexural, split tensile strength, UPV, dynamic modulus, water absorption, porosity and sorptivity tests were conducted for the composite gypsum phase containing different zeolite percentage. Results obtained show that 20% substitution of gypsum by zeolite provided maximum mechanical strength which can be chosen as optimum. The superplasticizers compensated for the loss in the workability caused by the addition of zeolite. The addition of polymer latex reduces the water absorption of gypsum plaster by modifying the micro-morphology of the gypsum plaster.

Effect of Low Zeolite Doses on Plants and Soil Physicochemical Properties.

Thousands of tons of zeolitic materials are used yearly as soil conditioners and components of slow-release fertilizers. A positive influence of application of zeolites on plant growth has been frequently observed. Because zeolites have extremely large cation exchange capacity, surface area, porosity and water holding capacity, a paradigm has aroused that increasing plant growth is caused by a long-lasting improvement of soil physicochemical properties by zeolites. In the first year of our field experiment performed on a poor soil with zeolite rates from 1 to 8 t/ha and N fertilization, an increase in spring wheat yield was observed. Any effect on soil cation exchange capacity (CEC), surface area (S), pH-dependent surface charge (Qv), mesoporosity, water holding capacity and plant available water (PAW) was noted. This positive effect of zeolite on plants could be due to extra nutrients supplied by the mineral (primarily potassium—1 ton of the studied zeolite contained around 15 kg of exchangeable potassium). In the second year of the experiment (NPK treatment on previously zeolitized soil), the zeolite presence did not impact plant yield. No long-term effect of the zeolite on plants was observed in the third year after soil zeolitization, when, as in the first year, only N fertilization was applied. That there were no significant changes in the above-mentioned physicochemical properties of the field soil after the addition of zeolite was most likely due to high dilution of the mineral in the soil (8 t/ha zeolite is only ~0.35% of the soil mass in the root zone). To determine how much zeolite is needed to improve soil physicochemical properties, much higher zeolite rates than those applied in the field were studied in the laboratory. The latter studies showed that CEC and S increased proportionally to the zeolite percentage in the soil. The Qv of the zeolite was lower than that of the soil, so a decrease in soil variable charge was observed due to zeolite addition. Surprisingly, a slight increase in PAW, even at the largest zeolite dose (from 9.5% for the control soil to 13% for a mixture of 40 g zeolite and 100 g soil), was observed. It resulted from small alterations of the soil macrostructure: although the input of small zeolite pores was seen in pore size distributions, the larger pores responsible for the storage of PAW were almost not affected by the zeolite addition.

Experimental and statistical studies of using the non-conventional water and zeolite to produce concrete

In the present study, the effect of simultaneous use of different non-conventional water types and zeolite percentages on the compressive strength of concrete was investigated. The experiment was conducted in two cement contents for long-term curing ages up to 365 days. Finally, data of 1176 cubic samples were statistically analyzed. Also, the relationship between water type, zeolite percentage, cement content, and curing age as independent variables and compressive strength of concrete as the dependent variable was extracted by the single and multiple linear regressions. Dummy coding was used in the regression procedure. Results showed that despite the significant decreasing effect of zeolite on the compressive strength of concrete in low cement content, a negative effect on this property was not seen up to zeolite usage 20% in high cement content. Also, while in low cement content, the use of all types of non-conventional water led to an increase in the compressive strength of concrete, in the high cement content, this property was reduced within the permissible limit of 10% by all types of non-conventional mixing water. Three-way interaction of zeolite percentage, water type and cement content on compressive strength of concrete revealed that negative effect of the simultaneous use of zeolite and non-conventional water compared to the condition of tap water and without zeolite usage mostly was less in the cement content 350 Kg.m−3 than 250 Kg.m−3. Finally, it was concluded that permissible limits of mixing water impurities of which are presented in the different standards possibly have not adequately credited for all conditions.

A novel approach to Chromium rejection from sewage wastewater by pervaporation

Pervaporation is an effective method, especially in the separation of azeotropic mixtures or in the recovery of some components from the mixtures. Although various methods have been used for the treatment of chromium-containing wastewater that has become a matter of concern for the health of aquatic ecosystems, the pervaporation has never been used before in the literature. In this study, Cr/water (Cr (III), Cr (VI)) mixtures were separated by a pervaporation using polyvinyl alcohol (PVA) and sodium Y (NaY) zeolite membranes. Study results indicated that increasing the zeolite percentage, the membrane thickness, the amount of Cr in the feed solution and, the pH all increased rejection and decreased flux. In contrast, an increase in temperature caused rejection to decrease and flux to increase. The best rejection obtained for Cr (VI) was 144.4%. For Cr (VI) removal from sewage wastewater, the maximum rejection under optimum conditions was 160% and the flux was 0.12 kg/m2h. Also, Cr (VI) was not detected in any permeates. The permeate concentration was calculated to be 97.1% in experiments with a Cr (III)/water mixture. PVA/NaY membrane showed selective permeability for Cr (VI), while it does not show selective permeability for the useful Cr (III) component.

Autogenous healing performance of internal curing agent-based self-healing cementitious composite

In this study, a series of cementitious composite with internal curing agent incorporating ranging from 0% to 30% were prepared to evaluate their autogenous healing performance. The Clinoptilolite Zeolite was utilized as an internal curing compound to replace parts of sand for storing the water inside the cement matrix. The mechanical properties were examined via compressive and splitting tensile tests. To quantify the self-healing behavior of this cementitious composites, the samples were pre-damaged using splitting tensile method and placed in the wet/dry cycle for several days. Two non-destructive testing methods, including resonant frequency and ultrasonic pulse velocity tests, were employed to assess the healing efficiency. The results revealed that the incorporation of zeolite could enhance the compressive strength and the self-healing performance of the proposed cementitious composites. However, if the replacement percentage of zeolite was higher than 15%, the healing efficiency decreased due to the “blocking effect”, which was further investigated by the water absorption test and thermogravimetric analysis (TGA).

Compressive strength of geopolymer concrete with fly-ash from Paiton Steam Power Plant and variations of substitution sodium silicate (Na2SiO3) with natural zeolite

Geopolymer concrete is one of the technological innovations of concrete without cement. It was prepared using fine aggregates, coarse aggregates, fly-ash, sodium hydroxide (NaOH), and sodium silicate (Na2SiO3). In the production of geopolymer concrete, sodium silicate and sodium hydroxide serve as an alkaline activator. One of the natural materials that can be used as an alternative material is natural zeolite. Zeolit contains high silica and alumina, that expected to increase the compressive strength of geopolymer concrete. This research aims to develop geopolymer concrete technology by understanding the setting time behaviour and compressive strength by substitution sodium silicate (Na2SiO3) with natural zeolite. The percentage of zeolite that substitute for sodium silicate is 0%, 2.5%, 5%, and 7.5 %. The molarity of NaOH is 12 M. Meanwhile, the ratio of sodium hydroxide and sodium silicate is 1:2.5. Compressive strength testing is carried out on cylindrical specimens 10 cm × 20 cm. The results show that natural zeolite can accelerate the setting time of geopolymer paste. The fastest initial setting time is 48 minutes. Meanwhile, the final setting time is 60 minutes in geopolymer paste with substitution sodium silicate using 7.5 % zeolite. In addition, for compressive strength results, zeolite can increase compressive strength. The highest average of compressive strength results is 46.07 Mpa in substitution of Na2SiO3 with 7.5 % zeolite.

Microstructural evolution in sulfate solutions of alkali-activated binders synthesized at various calcium contents

Alkali-activated binders based on metakaolin, fly ash and slag without curing were exposed directly in air, Na2SO4 and MgSO4 solutions for studying the evolution in mechanical strength and microstructure. A series of binders were synthesized and characterized on 7, 21, 45, 60, 75 and 90 days, respectively. Compressive strength measurement, scanning electron microscope (SEM) mapping, X-ray diffraction (XRD) and unclear magnetic resonance (NMR) were applied in the study. It is found that the exposure in sulfate solutions leaded to the deterioration of the binders by the dissolution of alkalis. In Na2SO4 solution, a higher percentage of zeolite was formed in the binders. While in MgSO4, a precipitate layer (e.g., brucite and gypsum), forming on the binder surface plays an important role in protecting the formation of gel, promoting the compressive strength improvement of alkali-activated slag, and compensating the decrease in compressive strength of alkali-activated metakaolin. These results provide clues for the direct preparation of alkali-activated concrete in aggressive sulfate environment.

Correlation of Unconfined Compressive Strength and California Bearing Ratio in Laterite Soil Stabilization Using Varied Zeolite Content Activated by Waterglass

In remote areas, most roads still use pavements that are very sensitive to climate change, especially those using clay pavements with high plasticity. In addition to the issue of cost, the difficulty of obtaining a proper source of material is another problem that has led to soaring prices for materials. In this regard, a study was conducted using local materials, namely zeolite as a stabilizing material added with waterglass as activating agent. The research began with samples of laterite soil and natural zeolite for XRD test (microstructure testing), and then testing for laterite soil’s index properties and engineering properties, namely Unconfined Compressive Strength and CBR value. The purpose of the test is to determine the correlation between the Unconfined Compressive Strength (UCS) and the soil bearing capacity (CBR) caused by adding zeolite as stabilizer material and waterglass as activator with increasing curing time. Laterite soils contain a brownish red iron oxide. The stabilizing material zeolite contains a crystalline mineral of alumina silicate SiO2. While waterglass composed of sodium meta silicate. Stabilization carried out by mixing 4%, 8%, 12%, 16%, and 20% of zeolite with addition of 2% waterglass, percentage was measured based on soil dry weight. Specimens were tested at curing time of 0, 7, 14, and 28 days. The test result shows increasing UCS and CBR values with increasing percentage of zeolite. At mix of 20% zeolite and 2% waterglass, the unconfined compressive strength reaches 23.54 kg/cm2 with CBR value 58% at 28 days of curing time.

PEMANFAATAN BATU ZEOLITE SEBAGAI AGREGAT KASAR PADA CAMPURAN ASPHALT CONCRETE BINDER COURSE (AC-BC) DENGAN BAHAN IKAT ASPAL PERTAMINA PEN 60/70 DAN STARBIT E-60

In the construction project, especially the roads in Yogyakarta and surrounding areas, the aggregate used is derived from the Clereng Kulonprogo. This amount of aggregate usage results in scarcity and affects the price to become expensive. The use of coarse aggregate materials as an alternative is rare. In reality, it is necessary to make innovation by utilizing the coarse aggregate of zeolite stone, which is still quite widely available in the Klaten area. Based on the preliminary test, the zeolite aggregate has a lower abrasion resistance compared to the andesite aggregate from Clereng. Using a modified asphalt Starbit E-60, which has a deficient penetration value, is expected to provide better stability to compensate for the weakness of zeolite stones. A combination of a mixture between a coarse aggregate of zeolite Stones and Andesite is tested until how large the proportion of zeolite stones of such combinations can provide the optimum value to AC-BC layer pavement. This research compares the performance of the AC-BC mixture using zeolite and andesite stones. It determines the feasibility of zeolites stone, in substituting the andesite stone, in the AC-BC mixture. It is also to know the influence of the use of Starbit E-60 in the AC-BC mixture. The comparison of those performances was referred to as Marshall characteristics, Indirect Tensile Strength (ITS), and Immersion; using Pen asphalt Pen. 60/70 and Starbit E-60 as a binder. Trial mix was applied to the bitumen content variation of 5%, 5.5%, 6%, 6.5%, to determine Optimum Bitumen Content (OBC) by conducting Marshall testing. The variety of substitution zeolite proportions of 0%, 25%, and 75% was made in each trial mix above. The research result showed that the maximum percentage of zeolite aggregate in the mixture using an asphalt Pen 60/70, which meets with specification standard, is 28%, while the mixture using Starbit E-60 is 26%. ITS value decreases as the percentage of zeolite are increased. ITS value of mix with Starbit E-60 is higher than that of mix with asphalt Pen 60/70. Cantabro Loss value increases with zeolite proportion increase, for both mixed with Starbit E-60 and asphalt Pen 60/70. Cantabro loss of mix with Starbit E-60 is lower than that of with asphalt Pen 60/70. IRS value decrease with an increasing proportion of zeolite.

Tổng hợp zeolite NaA/NaX từ tro trấu không nung bằng phương pháp thủy nhiệt

The development of technology and science as well as the growth of population cause the seriously polluted environment, especially the pollution of heavy metals. Synthesis of zeolites and their applications in adsorption, solid catalysts and ion exchange have been concerned. In this study, zeolite was synthesized from the precursor of sodium silicate originated from rice husk ash (RHA) without calcination by using hydrothermal method. The percentage of silica recovery from RHA without calcination was reached at about 90% when the optimal reaction conditions were at the ratio of RHA to NaOH = 1:10 (g/mL), the concentration of NaOH of 5 M, the reaction time of 3 h, the stirring speed of 300 rpm and the reaction temperature of 90oC. The parameters affected zeolite NaA/NaX synthesis such as ratio of SiO2 to Al2O3, the reaction temperature T1 (oC), reaction time t1 (h) and aging time t2 (h) were investigated. The results showed that crystal percentage of zeolite NaA/NaX was obtained at 52,7% during 4 h, 100oC, aging time of 12 h, ratio of Al2O3 to SiO2 of 2,5 and the ratio of Al:NaOH = 1:2 Although the crystal percentage of zeolite NaA/NaX in this study was not as high as that of other published researches, the in-situ synthesis used RHA without calcination and recovery of silica during the synthesis of zeolite NaA/NaX. Therefore, the synthesized process is environmental friendly as well as time and energy savings.

The Feasibility Study of the Use of Briny Groundwater and Zeolite in the Plain Concrete Mix Design in the Different Cement Contents

Abstract 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.
