Utilization of waste marble dust as cement and sand replacement in concrete

In this paper, CaCO3 waste marble dust (WMD) has been utilized in the production of concrete. Raw materials (Cement, Sand, WMD and Crush) were collected from Peshawar, Khyber Pakhtunkhwa, Pakistan. Concrete cubes were molded in the laboratory and investigated by XRD. Effect of WMD addition to the concrete was studied. It was reported that 10% addition of WMD as cement replacement showed enhanced performance of the compressive strength as compared to sand replaced WMD blended concrete. Increment in WMD contents beyond 10% resulted in significant decrement of compressive strength. Substituting WMD with cement resulted in a decrement of 29.76%, while with sand, the decrement was 6.09%. Concrete made with cement replaced WMD showed the lowest water absorption rate over 7 days curing as compared to sand replaced (intermediate water absorption) and clean concrete (highest water absorption) samples.Graphical

The Effect of Waste Marble Dust and Corncob Ash on the Engineering and Micro-Structural Properties of Expansive Soil for Use in Road Subgrades

This research investigated the effect of Waste Marble Dust (WMD) and Corncob Ash (CCA) on expansive soil's engineering and microstructural properties. Various laboratory experiments were performed on the natural soil to ascertain its characteristics. The corncobs underwent pre-water treatment for fourteen days to remove excess potassium and increase their silica content, resulting in a rise in the silica level from 0% to 50%. At first, only WMD was added to the soil in increments of 5% to 30% using compaction and California bearing tests. The optimum dosage of 15% WMD addition yielded the best result. CCA was then incorporated by the weight of the soil from 2% to 10% in increments of 2% to the first optimum (15% WMD) to obtain the overall optimum for the study (15% WMD and 8% CCA). Stabilization of the natural soil using both materials led to the modification and solidification of the soil mass, evident by the rise in California bearing ratio values from 1.68% to 15.53% and unconfined compressive strength from 41.33 kN/m2 to 174.68 kN/m2. There was also a decrease in the soil's free swell from 120% to 15% as well as reductions in the liquid limits from 56.23% to 36.01% and in the plasticity index from 29.74% to 8.72%, respectively. The microstructural images showed the formation of cementitious compounds in the form of calcium silicate hydrate and calcium aluminate hydrate gels. The findings indicate that using WMD and CCA as a unit has great potential in enhancing engineering properties, like strength parameters and the swell potential of expansive soils.

Investigation of Unsaturated Soil Hydraulic Properties for Subgrade Improvement using Marble Dust Waste

Introduction The distribution of suction, which has implications for seepage and shear strength, plays a crucial role in determining the stability of unsaturated soil. The Air Entry Value (AEV) and Residual Water Contents (RWC) change over time to create the Soil-Water Characteristic Curve (SWCC), which is very important for figuring out how the suction is distributed. During a flood occurrence, the subgrade becomes inundated with water, leading to adverse effects on the AEV and RWC of the subgrade. Consequently, the performance of the subgrade is diminished. This study focuses on the use of Marble Dust Waste (MDW) as an addition to the subgrade to improve the strength of the subgrade. Aims This study aims to investigate the variations in air AEV in relation to the optimal MDW in unsaturated soil found in Malaysia. Methods The study uses control samples and soil that has been mixed with different amounts of MDW: 5%, 10%, 15%, 20%, and 25%. The SWCC is generated using the pressure plate extractor device. Results The results indicate a significant increase in the AEV for the mixed soil sample when compared to the control sample. While the soil-MDW mixture containing 5% of this material has an AEV value of 23 kPa, the control sample's value is 10 kPa. Conclusion The findings of the study suggest that the utilization of MDW yields a beneficial influence on the AEV, hence potentially improving the performance of the subgrade. The researchers aim to evaluate the potentially dangerous waste and convert it into a substance that is appropriate for engineering applications. This study provides empirical evidence that aligns with the objectives outlined in Chapter 8 of the 12th Malaysia Plan for the period 2021–2025. The topic under discussion pertains to environmental sustainability, specifically focusing on enhancing the ability to withstand the adverse effects of climate change and disasters, as well as the Green Technology Master Plan Malaysia 2017–2030, with a specific emphasis on Chapter 6, which addresses the issue of waste management.

Thermal, thermomechanical and structural properties of recycled polyethylene terephthalate (rPET)/waste marble dust composites

The main objective of this work is to review the capability of using waste marble dust (MD) particles as reinforcing materials in recycled polymeric composites to achieve environmentally friendly materials. In the present study, polymer composites were fabricated from recycled polyethylene terephthalate (rPET) and MD and then analyzed for their structural and thermal properties. Preparation of rPET-based composites containing 0–20 wt% MD was carried out through extrusion and injection molding. For their characterization Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA) were applied. The DSC analysis revealed a nucleating effect of MD on rPET, which was manifested in a higher crystallization temperature (196.7 °C ⇒ 204.4 °C); however, the marble particles were also found to hamper chain mobility, thereby decreasing the crystallinity ratio (23.7 % ⇒ 19.2 %) of rPET and altering its crystalline structure. According to the TGA measurements, a slight increase occurred in the thermal stability of rPET, its major decomposition temperature increased from 446 °C to 451 °C when 20 wt% MD was incorporated into it. DMA showed an improved stiffness in the entire investigated temperature range for MD-filled composites versus neat rPET. Additionally, several factors were derived from the DMA data, including the effectiveness factor, degree of entanglement, and reinforcing efficiency factor which all suggested a decent interaction between the components indicating a proper reinforcing ability of marble powder. However, above 5 wt% MD content the reinforcing efficiency deteriorated due to the agglomeration of filler particles, which was also supported by scanning electron microscopic images.

Resistência à compressão e desempenho ambiental de cimentos com resíduo de serragem de mármore.

Abstract Replacing limestone filler by waste marble dust is one of the paths to explore, at a regional level, to stimulate circularity and reduce environmental burdens of ornamental stone processing. This study investigated six blended cements which combined supplementary cementitious materials (SCMs) and limestone filler or waste marble dust, with a clinker factor of 50%. Compressive strength was determined at 3, 7, 28 and 91 days and evaluated based on the criteria standardized in ABNT NBR 16697:2018. The cementing efficiency at 7 and 28 days of the set of mineral admixtures used and greenhouse gas (GHG) emissions intensity of each cement were also calculated. The synergy between the combinations reduced the clinker factor and cement GHG emissions, whilst preserving the mechanical performance required by the construction market.

Mechanical, freeze-thaw, and sorptivity properties of mortars prepared with different cement types and waste marble powder

The cement production process contributes significantly to CO2 gas emissions and environ- mental pollution. To reduce this adverse effect, the substitution of waste marble powder as a cement additive was investigated. In this study, the properties of mortar specimens were analyzed by using waste marble powder as a partial substitute for three different cement types: CEM I 42.5R Ordinary Portland Cement (OPC), CEM II/B-L 42.5R White Cement (WC) and CA-40 Calcium Aluminate Cement (CAC). Waste marble powder has been replaced with ce- ment at 5%, 10%, and 15%. The compressive and flexural strength, capillary water absorption, and sorptivity values of the prepared mixtures were determined before and after freezing and thawing. It was carried out after 28 days of water curing on 50 x 50 x 50 mm specimens for compressive strength and 160 x 40 x 40 mm specimens for flexural strength test. Freeze-thaw testing of the mixture samples was conducted according to ASTM C666 Procedure A. Test re- sults showed that the highest compressive strength before freeze-thaw was obtained in calcium aluminate cement-based mortars containing 10% by weight waste marble powder replacement for cement. The appropriate waste marble powder ratio was determined as 10% in all cement types used in the study. Before freeze-thaw, the mechanical properties of CAC-based mixtures were higher than those of other cement types. However, as the number of freeze-thaw cycles increased, the strength losses were more significant compared to OPC and WC.

Exploring waste marble dust as an additive in cementitious grouts for semi-flexible pavement applications: Analysis and optimization using RSM

This research aims to explore the potential utilization of waste marble dust (MD) within cementitious grouts for applications in semi-flexible pavements, a hybrid pavement type combining the benefits of both flexible and rigid pavements. MD was used to replace cement (ranging from 0 to 25%), combined with w/c ratios of 0.35 to 0.50, in the formulation of cementitious grouts. The assessment of grout characteristics encompassed evaluations of flowability and compressive strength (7d and 28d curing). Moreover, the microstructural characteristics of cement grouts incorporating MD were scrutinized through Scanning electron microscope-SEM and Energy dispersive X-Ray spectroscopy-EDS analyses. Additionally, response surface methodology (RSM) was used for experimental design, analysis, and the optimization of the factors (MD and w/c ratio). The significance of the model was examined through various statistical indicators. The optimal composition of cementitious grouts was determined using optimization technique within the RSM framework. Furthermore, optimal grout combinations were employed in fabricating semi-flexible mixtures and evaluated for Marshall stability, moisture susceptibility, indirect tensile stiffness modulus, dynamic modulus, compressive strength, and resistance to fuel spillage. The results indicated that an optimal combination of 15% waste marble dust and a 0.40 w/c ratio was identified through optimization techniques within the RSM methodology. Furthermore, Analysis of variance formula-ANOVA outcomes exhibiting a higher R² value (>0.80) and higher adequate precision (>4.0) underscore the significance of the proposed models, revealing a robust correlation between experimental and predicted data. The semi-flexible mixtures also showcase superior performance in terms of Marshall stability, stiffness, dynamic modulus, moisture resistance, and resistance to fuel spillage. Moreover, the integration of waste marble dust in cementitious grouts for constructing semi-flexible pavements not only addresses disposal concerns but also contributes to environmental sustainability.

Steady state analysis on sliding wear behavior of waste marble dust filled kenaf‐polyester composites

AbstractIn view of the rising demand of natural fiber reinforced polymers in engineering applications, the current research is taken on to study the effects of particulate filling in polyester‐kenaf fiber composite in terms of its sliding wear performance. A set of polyester‐based hybrid composites are fabricated with fixed kenaf fiber content and varied quantities of waste marble dust (0 wt. %, 16 wt. % and 32 wt. %). These composites are subjected to dry‐sliding wear trials as per ASTM G‐99 05 under different test conditions and the specific wear rate are estimated. The test results are analyzed to obtain the parametric appraisal of the wear process using response surface method. The analysis reveals that the filler content followed by sliding velocity, normal load and sliding distance has the detrimental impact on the specific wear rate of such hybrid composites. A morphological study is performed using a scanning electron microscope to identify prominent wear mechanisms and it is found that the wear loss is primarily due to the formation of wear tracks, cracks, craters, plastic deformation, wear debris and the removal of matrix layer etc. during the sliding process.

Investigation of the usability of industrial mining wastes in agriculture

In this study, the usability of the mixtures consisting of lignite coal taken from Tekirdag region and marble and travertine wastes taken from the marble factory in Gumushane region in local bean (Kelkit) cultivation was researched. First, control samples were created using only humus soil without coal, marble, or travertine dust. Then, for each coal or coal waste, coal/coal waste—waste marble dust and coal/coal waste—travertine dust mixtures were formed. These mixtures were obtained by mixing 25%, 50%, 75%, and 100% by weight of coal and 25%, 50%, and 75% by weight of marble and travertine dust. Afterwards, local beans were planted in these mixtures and their development was followed under laboratory conditions. Additionally, temperature and humidity values were recorded at certain intervals, pH and heavy metal analysis measurements were made on the mixtures before and after bean planting, the height and leaf measurement of the beans grown and the number of beans grown in these beans were also followed, and chlorophyll analysis was performed on the bean plants grown in these mixtures. As a result, 50% Coal-3D + 50% Travertine mixture had the maximum length increase, that 25% Coal Waste (Powder)-K3 + 75% Marble mixture had the highest number of beans, and that 50% Coal Waste -AK + 50% Marble mixture had the maximum leaf formation. In these mixtures, maximum 12 beans were grown and maximum 93 leaves were formed. Also, the bean plant was grown in all mixtures. The chlorophyll contents were at least as much as the values of the beans grown only in soil. However, heavy metal values do not exceed the permissible limit values in soil.

Laboratory Testing and Analysis of Clay Soil Stabilization Using Waste Marble Powder

Soil stabilization is a critical step in numerous engineering projects, preventing soil erosion, increasing soil strength, and reducing the risk of subsidence. Due to its inexpensive cost and potential environmental benefits, waste materials, such as waste marble powder (WMP), have been used as additives for soil stabilization in recent years. This study investigates waste marble powder’s effects on unconfined compressive strength (UCS) and clayey soil’s ultrasonic pulse velocity (UPV) at different water contents and curing times, and artificial neural networks (ANNs) are also used to predict the UCS and UPV values based on three input variables (percentage of waste marble dust, curing time, and moisture content). Geo-engineering experiments (Atterberg limits, compaction characteristics, specific gravity, UCS, and UPV) and analytical methods (ANNs) are used. The study results indicate that the soil is high-plasticity clay (CH) using the Unified Soil Classification System (USCS), and adding waste marble powder (WMP) can significantly improve the UCS and UPV of clay soils, especially at optimal water content, curing times of 28 days, and 60% WMP. It is found that the ANN models accurately predict the UCS and UPV values with high correlation coefficients approaching 1. In addition, this study shows that the optimum water content and curing time for stabilized clay soils depend on the grade and amount of waste marble powder utilized. Overall, the study demonstrates the potential of waste marble dust as a soil stabilization additive and the usefulness of ANNs in predicting UCS and UPV values. This study’s results are relevant to engineers and researchers working on soil stabilization projects, such as foundations and backfills. They can contribute to the development of sustainable and cost-effective soil stabilization solutions.

Influence of marble waste reinforcement on mechanical properties and sliding wear behavior of an aluminium alloy metal matrix composite

This study thoroughly analyse the effects of waste marble dust reinforcement in a metal matrix composite made of AA6061 aluminium alloy. The 3-weight percentage, 5-weight percentage, and 7-weight percentage of waste marble dust particles are used as reinforcement. The stir casting technique is used to fabricate the AA6061 based metal matrix composites. Marble dust was preheated at 200 °C before being used as reinforcement. Mechanical properties (tensile strength, micro-hardness, and impact strength) and sliding wear characteristics of the fabricated composites are studied. The sliding wear characteristics of composites were simulated under the pin-on-disc tribometer with varying control parameters. The selected control parameters are sliding velocity (150 rpm, 300 rpm, 450 rpm, 600 rpm), normal load (5 N, 10 N, 15 N, 20 N), and temperature (25 °C, 40 °C, 60 °C, 80 °C). Taguchi design is also used for an optimization of control parameters. Results indicate that a composite reinforced with 5-weight percent marble dust has good mechanical and sliding wear resistance properties compared to 3-weight percent and 7-weight percent marble dust reinforced composites.

Thermal and mechanical properties of a new insulation composite material

Abstract The Taguchi optimization method was used to optimize waste and natural different components such as waste marble dust, expanded perlite, perlite aggregate size, cement, and molten tragacanth in the production of new insulation composite material. Compressive strength, thermal conductivity, abrasion loss, and water adsorption properties of the developed composite material were investigated. Taguchi’s standard L18 array was chosen for optimization of these four components with different levels. Response plots were created using the Taguchi and the optimum test condition was determined. The insulation composite material with the best thermal and mechanical properties was obtained under the condition of waste marble dust (1), expanded perlite (1), perlite aggregate size (1) and molten tragacanth (1). In addition, using the anova (Analysis of Variance), percentage impacts on the mechanical and thermal properties of the test parameters were determined. Statistical values obtained from anova and mathematical models are developed by using multi-linear regression method. It was found that the mathematical model and the experimental results were quite compatible. The optimum test conditions detected were verified by confirmation experiments. Confirmation experiment results were obtained between 99.9 % confidence interval values.

Shear behaviour of reinforced concrete beams utilizing waste marble powder

Today, it has been determined that waste marble dust (WMD) is not evaluated and therefore creates environmental problems. For this reason, in this study, the usability of WMD in different proportions, in which waste materials are evaluated, was investigated. Thus, it is aimed to eliminate the existing environmental problems by ensuring the use of WMD in reinforced concrete beams (RCBs). Pursuant to this motivation, an experimental program was carried out on 15 shear deficient RCBs, considering different WMD and stirrup spacing. While the proportion of WMD in the RCBs was chosen as 10%, 20%, 30% and 40% by weight, respectively, the stirrup spacing was considered as 270 mm, 200 m, and 160 mm. Concrete compressive strength (CCS) is generally adversely affected while WMD is used instead of cement at 10% or more rates. In RCB samples with the stirrup spacing of 270 mm, 200 mm, and 160 mm, 10%, 20%, 30%, and 40% WMD additives reduced the bearing capacity of the RCBs compared to the reference sample. It has been observed that ACI 318 (2019) and EC2 (2004) design regulations demonstrate excellent performance (maximum 85% success) in estimating shear strength up to 20% marble dust admixture in RCBs where the stirrup spacing is 200 mm and 160 mm. The results revelaed that using up to 5% of WMD instead of cement has approximately no negative influence on the CCS. Nevertheless, if this percentage is chosen as 10% or more, it has been found that the CCS is commonly destructively affected.

Performance of hot-mix asphalt using polymer-modified bitumen and marble dust as a filler

Marble dust waste powder generated by the marble cutting industry has a high alkalinity. In this research, the use of marble dust (MD) as a mineral filler substitute in hot mixed asphalt (HMA) was evaluated. The Marshall mix design was used to determine the optimum bitumen content (OBC) for all of the mixtures. For each of the four MD contents, i.e., 0, 2%, 4%, and 6% by weight of the total aggregates, four different bitumen percentages were used. The results of the Marshall stability test showed that the optimum filler content was 4% MD. Samples were prepared with 0 MD in the control mix and varying percentages of MD as an alternate filler. In addition, MD aided in increasing the Marshall stability, rutting resistance, and permanent deformation and reduced the fatigue life of asphalt mixtures. As the percentage of MD increases, the rutting resistance and stiffness at high temperatures both increase. As the percentage of MD increases, the fatigue life reduces. Rut resistance in high-temperature conditions can be improved by using MD in HMA as a partial substitute for stone dust (SD). In areas where extensive MD waste is present, MD can be incorporated into HMA mixtures instead of conventional fillers.

Developing a geopolymer pastes using marble dust

ABSTRACT This paper investigates the use of marble dust waste, fly ash, and silica fume as raw materials for manufacturing geopolymer pastes. The chemical composition of each raw material is established using chemical analysis (X-ray fluorescence XRF) and mineralogical analysis, X-ray diffraction (XRD) pattern of raw materials. The experimental work was divided into three groups (A, B, C) according to the water to binder ratio (w/b) (A =28%, B = 30%, C = 33%). Each group is further divided into five subgroups according to the percentage of marble dust, fly ash, and silica fume. The samples are cured at 60°C for three days. The properties of the geopolymer pastes are determined by performing the following tests: compressive, tensile, and flexural strength and water absorption. The highest mechanical properties were obtained from mixes containing 70% fly ash and 30% marble dust at w/b = 0.28. It was 40% more than those obtained from control mixes containing 50% fly ash and 50% marble dust. It is worth mentioning that the best amount of marble dust was 30% as the resistance of the geopolymer paste reached values up to 237.8 kg/cm2. The results were confirmed by SEM imaging.
