An estimation of one billion tires is expected to end their useful life annually, of which only roughly 50% are recycled at the moment, with the remainder ending up in landfills. Consequently, to solve this gap in the ELT's utilization rate, it is imperative to enhance the current application and furthermore create new applications for recycled tire materials. One of such areas that is currently being investigated is the introduction of waste tire into concrete as partial replacement of natural aggregates in concrete production. Despite its great prospects, it has drawbacks such as lack of proper bonding with the cement matrix and weak rubber intrinsic strength, which make it unsuitable for widespread usage as an aggregate. To get past this obstacle, numerous rubber treatment techniques that enhance the mechanical characteristics of rubber concrete remarkably as well as the bonding properties have been studied by researchers. The impact of rubber percentage replacement, rubber aggregate size and different treatment techniques on various mechanical characteristics of rubber concrete are examined in this review paper. But in order for the concrete industry to embrace it, the researchers need to devise a rubber treatment technique that can tackle the issues of high combustible and the harmful gases that are released from the rubber aggregates when they come in contact with fire.</p></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"12 ","pages":"Article 100237"},"PeriodicalIF":0.0,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772397624000212/pdfft?md5=7f968c8364a56c6a3ca01297af8fc685&pid=1-s2.0-S2772397624000212-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140179943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the application of pulsed laser ablation (PLA) in fabricating polymer-based magnetic nanocomposites, with a focus on polyvinylpyrrolidone, chitosan, and methyl cellulose. These polymers, renowned for their proficiency in adsorbing pollutants from various oils, were combined with magnetite nanoparticles (NPs) in a compressed tablet form. The PLA process facilitated the generation of nanocomposites, which were subsequently collected using an external magnetic field. The chemical composition of these composites was analyzed through Fourier-transform infrared (FTIR) and Raman spectroscopy, while particle sizes were determined using the Leica Image Processing and Analysis System. The study revealed that PLA is a green, single-step, and effective technique for preparing magnetic nanocomposites, producing particles predominantly in the 400 nm–4 µm size range. Furthermore, the application of these composites in oil/water separation demonstrated with separation commencing approximately 1 s after the application of a magnetic field.

The effects of the type of powder (CoW-powder, CeW-powder and RCBW-powder) and of the liquid/solid (L/S) ratio on the mixture properties in the fresh and hardened states were studied. In the fresh state, the level of flowability (mini-slump), flow index (flow table), buildability and setting time characteristics of the cementitious pastes were evaluated. In addition, the rheological behaviour was analysed through a rotational rheometer. In the hardened state, the compressive strength was determined at 3, 7, 28 and 90 days. The effects of the type of recycled fine aggregate (RFA − CoW, RFA − CeW and RFA − RCBW) were evaluated for mortars with a cement:aggregate ratio of 1:0.5. Based on the results obtained, the most suitable mixtures were selected to carry out 3D printing tests on a laboratory scale. From the 3D printing of beam-type specimens, it was possible to determine the flexural and compressive strengths (28 days) of the selected mixtures. The results obtained validated the possibility of using recycled powders (CoW, CeW and RCBW) to replace 30 % of ordinary Portland cement (OPC) and to incorporate 100 % recycled fine aggregates in the design of cementitious materials (pastes and mortars) for 3D printing. In this regard, the recycled powders and recycled fine aggregates increase the buildability and thixotropy of cementitious mixtures. With an adjustment in the L/S (liquid/solids) ratio, their application in 3D printing becomes feasible. This alternative for the use of powders and fine aggregates from construction and demolition waste (CDW) could be considered a contribution towards the sustainability of the sector and the implementation of a circular economy.</p></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"11 ","pages":"Article 100234"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772397624000182/pdfft?md5=f659693cc1025f7fbbde563281d18ec1&pid=1-s2.0-S2772397624000182-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140052038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study presented conceptual scale-up process design, base-case techno-economics and Monte-Carlo simulation of zeolite Y recovery from Nigerian metakaoline. ASPEN Base Case Simulation (ABCS), scale-up design and economics were accomplished using inherent design and costing algorithms in ASPEN Batch Process Developer (ABPD) V10.

Monte-Carlo Simulation (MCS) in Crystal Ball Oracle software was used to perform the sensitivity and uncertainty analyses.

This research endeavor seeks to investigate a supervised data-driven approach for predicting STS and FS in concrete composites incorporating MWP, along with other cementitious materials such as silica fume (SF), granite powder (GP), and fly ash (FA), and their influence on the STS and FS of MWP-incorporated concrete.

Statistical metrics like correlation coefficient (R2), root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE) are used to evaluate the performance of each ML algorithm. To enhance model efficiency, hyperparameter tuning and a 5-fold cross-validation technique are implemented. Among the ML algorithms tested, the cat boost algorithm demonstrates superior performance in predicting STS, while the ANN algorithm excels in predicting FS.

The main aim of this study is to select an ideal MAM with excellent physical, electromagnetic, chemical, and thermal properties, which also fulfills sustainability aspects based on expert judgments. In this regard, we have proposed a new hybrid framework consisting of Modified Digital Logic (MDL), a subjective weighting method in combination with the measurement of alternatives and ranking according to compromise solution (MARCOS) under an interval-valued intuitionistic fuzzy (IVIF) environment to select an optimum MAM. Furthermore, this research work contributes to streamlining the selection process by consolidating the plethora of work available in the literature on the synthesis and characterization of MAMs. A database is created for 160 potential candidate materials in C, S, X, and Ku bands for carbon-based materials, including carbon nanotubes (CNT), graphene, reduced graphene oxide (rGO), carbon fibers, and biomass-derived materials. These materials are then passed through successive screening stages to shortlist 14 materials, which are ranked subsequently over a set of 15 crisp and ambiguous criteria. This comprehensive study simultaneously caters to quantitative and qualitative information extracted from experimental work, material resource packs, or expert evaluations. The findings highlight CNT/Fe (20 wt%, E) (Al1) as the most suitable candidate for MAM application with outstanding electromagnetic properties.
