“…[19,20] Studies have demonstrated the utilization of marble waste as a substitute for natural sand in concrete, [21] as a part replacement in cement, [22] as a filler in polymer matrix composite, [23,24] in geopolymer based bricks, [25] in ceramic composite bricks [26] and in low-density polyethylene for the application in electrical insulating material. [27] Very limited literature has been found on the utilization of marble waste in PVC. In a work, the researcher used dolomite and marble power up to 20 phr in PVC resin and reported an improvement in tensile and impact strength along with increment in Vicat softening temperature.…”

In this study, flexible poly(vinyl chloride) (PVC) composites with two different types of fillers, precipitated calcium carbonate (PCC) and marble waste (MW) particulates, were prepared via melt processing. The MW collected from a dumping site, had a particle size of approximately 60 μm and high calcite content. The content of fillers and plasticizer was varied to study the effect on the properties of the composites. It was found that at higher plasticizer content (30 phr), MW afforded up to 9% higher tensile strength compared to PCC, indicating a better interfacial adhesion of MW particulates with the matrix. However, at lower plasticizer content (15 phr), composites with PCC exhibited slightly higher tensile strength. Additionally, at high plasticizer content, the addition of MW up to 10 phr afforded better tensile strength than pure PVC.When the composites were fully submerged in the water for 48 h at elevated temperature (60 C), composite with MW had a slightly higher water absorption (0.4-1.4%) compared to PCC-filled composites. Also, composite with higher plasticizer showed elevated water uptake at any particular filler content. The study categorically proves the potential of MW in flexible PVC formulations as a cost-effective sustainable filler.

“…In this context, marble dust has been explored globally. [3][4][5][6][7][8] Fiore et al [3] studied an outcome of the content of marble dust and plasma treatment on different properties of epoxy-based composites. They determined the tensile, flexural, impact and thermal behavior of the material.…”

“…Contrary to Cinar and Kar [ 4 ] observation, Awad et al [ 5 ] found that the hardness of composites prepared with smaller size particles is greater as compared to the composites prepared with larger size particles. Khan et al [ 6 ] studied the effect of different processing temperatures (110 °C and 140 °C) during the fabrication of composites via injection molding. While studying the mechanical properties, they found that the flexural and tensile properties are better when the processing temperature is high, whereas, the impact strength is better at low processing temperature.…”

Kota stone dust (KSD) and fly ash (FA) are the wastes generated from the construction industry and thermal power plant, respectively. In the present work, a novel hybrid composite is developed to utilize KSD and FA as reinforcing phases in the epoxy matrix. The hand lay-up method is adopted for the fabrication of 12 sets of samples. Four sets are prepared with single filler KSD and eight samples are prepared with a hybrid combination of KSD and FA. The prepared samples are undergone physical and mechanical tests. To understand the compatibility between filler-matrix and visualize the dispersion of fillers in epoxy, micrographs are taken using the scanning electron microscope. The density and void contents of the material increases with an increase in filler content. The maximum water absorption measured is 0.96% for the combination of epoxy with 40 wt% KSD and 10 wt% FA. From mechanical testing, maximum tensile strength and flexural strength obtained is 34.4 MPa and 65.4 MPa, respectively, for a combination of epoxy with 20 wt% KSD and 5 wt % FA. Compressive strength and hardness increase with either of the content of the filler and reaches 116.28 MPa and 104 Shore D number, respectively, with 40 wt% KSD and 10 wt% FA. From experimentation, it was found that mechanical properties of the hybrid composites are better as compared to that of single filler composites though physical properties are slightly compromised by hybridization of fillers.

“…Figure 9:1C,D demonstrates smooth surface of SBR nanocomposites with WM and TWM at 5 wt% also, elaborating on the positive records of the mechanical analysis. [ 24 ] Evidently, Figure 8 of NBR‐nanocomposites reveal more smoothness and homogeneous distribution of the filler inside rubber texture than that of SBR‐nanocomposites confirmed the superior mechanical properties of the fabricated NBR/WM, TWM above SBR/WM, TWM. On the other hand, Figure 9:2 demonstrates good dispersion and uniform surface compared with unirradiated composites for all explained graphs, revealing the developed radiation‐induced network structure generated by irradiating NBR and SBR/untreated and treated waste marble nanocomposites, with the integral dose 100 kGy.…”

A comparative study on two nanocomposites based namely on acrylonitrilebutadiene (NBR) and styrene-butadiene (SBR) synthetic rubbers, reinforced by varying ratios of waste nanomarble particles (WM) was carried out. Silane which served as coupling agent was applied in treating waste marble (TWM) and the characters of the prepared nanocomposites before and after treatments were examined. Nanocomposites were fabricated using a laboratory roll mill and pressed under heat, then irradiated with gamma-rays at 100 kGy. Filler characterization, using the techniques transmission electron microscopy (TEM), FTIR spectroscopy, and X-ray diffraction (XRD) were discussed. TEM micrographs revealed that though untreated WM particles were within the nanometer scale, however showed incremental reduction in size via silane treatment. Mechanical parameters, thermal stability, FTIR and scanning electron microscopy (SEM) of the advanced NBR and SBR nanocomposites have been studied. Filler loading with 5 wt% led to remarked improvement in the tensile strength (TS), modulus of elasticity (M 100 ), and tearing strength of the NBR nanocomposite samples. Meanwhile, elongation at break of SBR nanocomposites exhibited regressive behavior. Thermal stability testing of pristine NBR and SBR specimens demonstrated adverse features by compounding with untreated and treated waste nanomarble. Furthermore, gamma irradiated NBR nanocomposites reinforced with TWM indicated appreciable development at all thermogravimetric stages. Whereas, irradiation of SBR nanocomposites with a gamma integral dose of 100 kGy resulted in slight enhancement in thermal stability.
