The study aims to review the research works on geopolymer concrete fortified with diverse elements like GGBFS, nanomaterials, and natural Fibres. The research employs a multidisciplinary methodology, encompassing a comprehensive assessment of previous experimental studies conducted by the investigators to examine the mechanical and structural characteristics, as well as the durability and microstructural aspects, of composite materials used in the production of geopolymer concrete. Materials under investigation include Fly ash, GGBFS, Nanoclay, bamboo, sisal, and hemp fibres. Findings from the literature review reveal that compared to a control mix, the notable improvements in compressive, tensile, and flexural strength by integrating GGBFS and Nanoclay are 15 %, 27 %, and 106 %, respectively. Adding hemp fibres at 5 % volume fraction, Fly ash, and GGBFS amplifies the water absorption capacity by 20 %. Sisal fibre was utilized as reinforcement in glass composites to develop a multilayered sisal-glass composite in polyester matrix optimal configuration (4 glass and 9 sisal layers) demonstrated excellent mechanical properties, including a tensile strength of 57.60 MPa, flexural strength of 36 N/mm², and 10 % moisture absorption, offering superior performance and cost-effectiveness. The findings highlight the effectiveness of strategic fibre layering in enhancing composite strength and cost efficiency. Natural fibres like hemp, bamboo, and sisal also improve the composites hardness and tensile characteristics. These consequences highlight the possibility of incorporating supplementary materials in geopolymer concrete, offering substantial improvements in mechanical and durability, environmental sustainability, and cost-effective construction solutions.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"16 ","pages":"Article 100310"},"PeriodicalIF":0.0,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to examine the impact patterns of USP (a novel warm-mix additive) and Sasobit, both as individual entities and in combination, on the rheological and conventional characteristics of high viscosity asphalt. Additionally, the study seeks to delve into the mechanisms of action underlying these two distinct categories of warm-mix additives. The results of the research indicate that both warm-mix additives are effective in reducing temperatures when used alone or in combination. When used alone, USP shows significant advantages in low temperature performance, superior to both conventional hot mix asphalt and Sasobit warm-mix asphalt. The high temperature performance of USP modified asphalt is closely related to its dosage. On the other hand, the use of Sasobit alone can improve the high-temperature performance and creep recovery properties of high viscosity asphalt, but results in a decrease in low-temperature performance. When USP is blended with Sasobit, the resulting asphalt exhibits both good high and low temperature performance, with a significant improvement in aging resistance observed in the 5% USP and 2.5% Sasobit group. In conclusion, in order to ensure that warm-mix additives have a beneficial effect on the properties of high viscosity asphalt, the combined use of multiple warm-mix additives can be considered comprehensively to achieve a balance between low carbon emissions and excellent performance.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"16 ","pages":"Article 100308"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143791141","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}

Reusing construction materials and increasing reuse effectiveness have emerged as popular study areas. Recently, the durability of recycled aggregate concrete (RAC) has drawn attention of numerous researchers worldwide. This review paper discusses the different approaches used to predict the durability of RAC (deterministic, probabilistic, and artificial intelligence). In addition, a critical review of the parameters more influential on the RAC durability performance is presented, including replacement ratio, particle size, chemical admixtures and additives, mixing technique, and curing conditions. Several contradictory results concerning the chloride ingress, carbonation, air and water permeability in the RAC are reported and discussed. The methods used to enhance the characteristics coarse recycled aggregate (CRA) are also categorised and summarised. We have found that complex, non-linear, and multivariable mechanisms control chloride ingress, carbonation, and permeability, rendering conventional modelling techniques inadequate. It is therefore advised to use artificial intelligence methods supported by comprehensive databases to provide precise durability predictions. The performance of RAC is greatly impacted by the adhered mortar (AM) in CRA; its increased porosity and water absorption result in weaker interfacial transition zones (ITZs), decreasing impermeability, and weakening resistance to carbonation and chloride ingress. Therefore, we have also reported that strengthening the microstructure or altering AM characteristics are the main treatment strategies used to increase RAC durability performance. By enhancing RAC performance and lowering the ecological footprint of construction and demolition waste, CRA carbonation stands out among these techniques as a potential technology that offers both technical and environmental benefits.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"16 ","pages":"Article 100306"},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769049","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}

The use of alternative SCMs also addresses the reliance of UHPC mixtures on silica fume.

The findings demonstrated that incorporating up to 50% GGBF slag as cement replacement significantly reduces the UHPC’s environmental impacts without jeopardizing the main mechanical and durability characteristics.

Reducing sFF emissions is of global concern, but there are few source reduction options. sFF emissions vary by fixed factors such as the type of garment edge treatment, the type of fiber or fabric (e.g. staple vs. filament, or surface treatment such as fleece), washing machine type, water conditions, and drying conditions. However, detergent effects are less studied and, while using any detergent—especially powder—may increase sFF emissions, the concept of liquid detergents formulated to reduce sFF emissions remains unexplored. Here, we report a novel “low shed” detergent’s comparative effects on sFF mass emissions, from two studies. First, four institutions washed each of four fabric types using either a conventional detergent or a novel (low shed) detergent, finding that the latter decreased sFF mass emissions despite institutional—operational and methodological—differences. The masses of sFFs per mass of textiles averaged, for each of four institutions, 0.08 ± 0.06, 0.07 ± 0.07, 0.05 ± 0.04, and 0.08 ± 0.04 g/kg when using the novel detergent, versus 0.23 ± 0.13, 0.16 ± 0.11, 0.14 ± 0.05, and 0.11 ± 0.05 g/kg for the conventional detergent. Despite multiple fixed differences in washing conditions across the institutions, the sFF shedding amounts significantly differed according to detergent. Second, for studies at one institution, textile fiber fragment (FF) mass emissions from laundering whole garments comprised of mixed synthetic and cotton fibers were also comparatively decreased with the low shed detergent during washing, wherein the novel detergent resulted in significantly less FF (0.37 g/kg) than the conventional detergent (0.50 g/kg; Wilcoxon test, <em>p</em> = 0.02, n = 8). Although whole garment FF masses captured from the machine dryer (lint trap plus dryer exhaust) did not vary by antecedent detergent (0.50 and 0.49 g/kg, using the novel versus conventional detergent, respectively), the overall garment laundering process across washing and drying emitted relatively decreased FF masses with the low shed detergent (0.87 g/kg) compared to the conventional detergent (0.99 g/kg, <em>p</em> = 0.02). Taken together, the results of this study demonstrated that detergent type could be an important factor in determining the release of sFFs and FFs during laundering, with a possible way to reduce the release being intentional detergent formulation.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"15 ","pages":"Article 100303"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579112","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}
