Keeping this in mind, this paper aims to summarise and discuss the reported findings on the mechanical and durability properties of alccofine-1203 based concretes. It is also aimed to give a better understanding of the behaviour and effect of alccofine-1203 as an SCM in various types of concretes. The alccofine-1203 has ultra-fine particles with a unique chemical composition that improves the hydration process and pozzolanic reaction. Therefore, its incorporation in concrete has resulted in good workability, reduction in segregation, reduction in heat of hydration, and reduction in permeability to concrete, and increased the rate of hydration process and improved the pozzolanic reaction to achieve high strength to concrete at the early curing stage. The presence of calcium (CaO) and silica (SiO2) in alccofine-1203 improved the mechanical and durability properties of concrete better than the other SCMs. From the literature review, the optimum dosage of alccofine-1203 is obtained between 8% to 12%, and at these percentages, the improvement in mechanical and durability properties of the concrete is highest.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"2060 - 2073"},"PeriodicalIF":3.7,"publicationDate":"2021-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47566644","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}

This study presents a comparative life cycle assessment between two refrigeration systems, the first operating with a traditional fluid and the second with a natural refrigerant. The analysis was performed in accordance with international standards ISO 14040/14044 and adopted the attributional life cycle assessment approach. The functional unit was: ‘the storage of meat products, at the temperature of 0°C for a lifetime of 10 years, in refrigerating cells of a medium city supermarket’. Three different scenarios were analysed to investigate the effect of the energy mix in relation to the use of the machines. Results highlight how the choice of the refrigerating fluid has a higher effect on the environmental performances of the machine with a reduction of approximately 10% in a whole life cycle. Scenario analysis shows how the use of such machines in different countries allows a significant reduction of environmental impacts mostly related to the use phase. Eco-design actions were listed and connected with environmental hot spots specifying the life cycle phases and the environmental indicators involved.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1623 - 1646"},"PeriodicalIF":3.7,"publicationDate":"2021-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43940907","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}

Solar energy sources from Vredendal, located in the Western Cape Province of South Africa, were used for the study. Assessment was performed for a refuelling station having capacity to meet the hydrogen needs of 25, 50 and 100 number of vehicles per day. The results showed that the annual daily average solar irradiation on the horizontal surfaces and optimally tilted surfaces were 5.77 kWh/m2 and 5.933 kWh/m2, respectively. The solar power required to meet the hydrogen production demand for each of the three refuelling number of vehicles were determined to be 2.24, 4.24 and 8.95 MW, respectively. The cost of energy from the solar PV system as well as the cost of hydrogen production at the refuelling station for each of the three hydrogen vehicle capacities was calculated as (0.24, 0.239 and 0.237) $/kWh and (16.52, 15.95 and 15.67) $/kg, respectively. The PV system would displace 387, 774 and 1548 tons of coal per annum for each of the capacity, respectively. This will result in the avoidance of 780, 1560 and 3120 tons/yr of CO2, respectively.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1843 - 1857"},"PeriodicalIF":3.7,"publicationDate":"2021-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47720804","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}

Looking for the capacities and sources of these communities, the oilseed production capacity is the most promised. So, a easy to handle pilot plant for cracking oils and fats was developed to produce biofuels. This study aimed to analyse the mass and energy balances of the pilot plant to check its viability for sustainable energy supply. For this, three different cracking temperatures (663 K, 678 K and 693 K) were studied, and reaction data was collected. The physicochemical properties are similar to those of petroleum diesel, indicating that thermal cracking fuel may be a viable alternative to this fossil fuel in diesel cycle engines. The best temperature for the cracking reaction was 678 K, due to the physicochemical parameters of the biofuel produced being similar to those of fossil diesel. So, according to energy production system, the cracking temperatures 678 and 693 K are recommended.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1800 - 1808"},"PeriodicalIF":3.7,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42953819","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}

This study presents an integrated framework based on Analytic Hierarchy Process (AHP) and Interpretive Structural Modelling (ISM) to evaluate potential alternatives for the SSCM. The criteria used for the selection of various enhancers of sustainability, which are developed along with the categories are environmental, economic, social, technical, organisational and business. An Indian-based engine manufacturing industry is taken to build up the model. AHP is employed to select the best criteria from the various Critical Success Factors (CSFs) listed under the categories based on the calculated weights. ISM and Matrice d’impacts croisés multiplication appliquée á un classment (MICMAC) analysis are employed to model the relationship among the various CSFs and to select the best from the developed matrix. The result indicates ‘support from senior management for environmental activities’, ‘environmental teamwork’ and ‘government support’ are the main CSFs for the achievement of sustainability of the supply chain.","PeriodicalId":14400,"journal":{"name":"International Journal of Sustainable Engineering","volume":"14 1","pages":"1496 - 1508"},"PeriodicalIF":3.7,"publicationDate":"2021-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48587355","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}
