“…According to the estimations, the proportion of the MD being generated during the cutting of marble bricks is about 20-35%, however, this number highly depends on the size and the shape of the cut blocks [13]. Reportedly, there is about 12 million metric tons of this MD generated in India each year, with Rajasthan state being the number one in releasing the most [14]. Stone cutting is generally performed with the help of water, which plays a triple role by lubricating and cooling the cutting blades, while also collecting the dust with a typical particle size below 200 µm [15].…”

The aim of this present work was to study the applicability of waste marble dust (MD) in poly(lactic acid) (PLA)-based composites. Samples containing up to 20 wt% waste MD were prepared via melt blending. The attention was focused on the investigation of mechanical, morphological, thermal properties and the wear resistance of the PLA/MD composites. Regarding the mechanical properties, both the tensile and the flexural modulus improved remarkably, however, a slight loss was observed in strength and deformability. The impact toughness showed an increasing tendency up to 10 wt% MD loading, which was followed by a marginal decrease at higher concentration. With respect to the sliding wear rate, the composite with the highest MD content showed the best wear resistance. According to the DSC measurements, the MD hampered the chain mobility of PLA, thereby reducing the crystalline ratio. Overall, composites with improved properties were developed, while the reuse of waste MD is expected to reduce the production costs as well.

“…Tests were performed at different curing ages and the compression tests were done in Compression testing machine. There is a huge traffic for further research in recycling which makes sustainable and green materials, generating employment from marble waste concrete production ensures provision of income to urban and rural mass while arresting further pollution of the environment [6], [7]. Further research could be done on fire resistance, acid resistance, durability and flexural strength of this kind of ceramic waste tile concrete [8].…”

Recycling the waste has been one of the most influential aspect affecting global conditions of the world. In the world of Civil Engineering, it serves the purpose of preservation of the natural building materials such as Sand, Stones, etc. Fair amount of work been done on utilization of the waste such as Fly ash, marble waste, tiles waste, plastic, etc. used as different forms of replacement, provokes the need of work still to be done. So much of the work has been done on wastes available from Marble and Tiles. The combined effect of waste marble powder (M.P) and Ceramic tile waste (CTW) as partial replacement of Cement (10%) and Coarse Aggregates (10%,20%,30% respectively) is to be observed and analyzed. The obtained results will be compared with the conventional cement concrete at 7 and 28 days of Curing. Total 24 number of cylinders casted and tested for their workability and Compressive strength. The Workability of Concrete with replacement decreased with increasing ratio of replacement as well as its Compressive Strength. The Compressive strength of concrete with replacement is approximately of same value as that of Conventional Concrete at (10%+10%) partial substitution ratio.

“…The reaction process of geopolymers is a process of repolymerization after depolymerization. During this process, the fly ash spherical particles are dissolved, the Al-O and Si-O bonds are destroyed, and new non-crystalline gelatinous substances are formed [46][47][48][49][50][51][52][53][54]. The XRD patterns showed that the main components of the polymerization products were amorphous structures.…”

The treatment of goaf subsidence is important for sustainable development. Geopolymer is a new type of cementing material with excellent mechanical properties, durability, corrosion resistance, and other advantages owing to its unique three-dimensional spatial aggregation structure. Herein, a type of preparation technology of fly-ash-based foamed geopolymer suitable for goaf filling was developed by adding a chemical foaming agent to the matrix of fly-ash-based geopolymer. The mechanical properties, chemical composition, and pore structure characteristics of the samples were discussed. When the samples with different contents of fly ash, sodium metasilicate, sodium stearate, H2O2, and NaOH were prepared, a uniaxial compression test was performed to analyze the uniaxial compression failure characteristics and compression strength of the samples. The mineralogical composition of each sample was analyzed by X-ray diffraction (XRD) test, and the microstructure images of different samples were observed using scanning electron microscopy (SEM). The effects of the content of each component on the properties of the samples were discussed. Finally, the CO2 emission, energy consumption, and cost of producing fly-ash-based foamed geopolymer were analyzed. Overall, the material had the advantages of low energy consumption, low CO2 emission, environmental-protection ability, and waste utilization and thus has a broad application prospect in treating subsidence.
