In this study, four mixtures of lightweight selfcompacted concrete with different fillers were tested. The tests were conducted by considering the ages of the specimens, which, in this study, were two, three, and five years old. The results show the residual mechanical properties of the specimens after they were heated to target temperatures of 300, 500, and 700 °C. After exposure to high temperature, the specimens were either left to gradually cool until they reached room temperature or rapidly cooled by water. A comparative analysis was conducted on the compressive strength, mass, and dynamic modulus of elasticity of the specimens using the codified residual values given in EN 1994 12.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"23 1","pages":"1-12"},"PeriodicalIF":0.2,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66266218","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}

An increase of its production results in more landfills. It is mostly used as a building material in the construction of roads, where it substitutes natural materials. The use of steel slag in road construction has multiple benefits; both by solving the challenges of waste disposal and preserving environmental resources by moderating the consumption of non-renewable and natural aggregates. Apart from being used as a building material, steel slag is also used in numerous environmental applications, such as soil and water remediation and CO2 sequestration. However, a multidisciplinary environmental impact study of steel slag, particularly regarding both the aquatic and terrestrial organisms, is lacking. Steel slag contains traces of potentially harmful elements that endanger these living organisms, including heavy metals released into the environment. A high pH value can also significantly influence their leaching properties, thereby affecting the organisms in the water and soil. Given the widespread utility of steel slag, it is recommended to make a thorough risk assessment associated with the various environmental applications of this material.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"19 1","pages":"13-22"},"PeriodicalIF":0.2,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43079568","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}

Obtained results indicate that landfill L was in methanogenic phase of waste decomposition and included the presence of two species of microorganisms: Escherichia coli and Klebsiella pneumonia. Additionally, a semi-quantitative screening analysis of collected samples was performed using QP2010-Ultra GC-MS. Sixteen organic compounds were identified, of which the following five belonged to the group of pharmaceuticals: caffeine, 22-tricosenoic acid, 4-methylthiomorpholine-1,1dioxide, 2,6,10,14-hexadecatetraen-1-ol,3,7,11,15-tetramethyl-,acetate,(E,E,E)-, and 1,2bis(trimethylsilyl)benzene. The software package STAN was used to conduct material and substance flow analysis. Scenario modeling was performed to assess the removal efficiency of selected technologies in terms of reducing the concentration of caffeine because of its well-known negative effects on humans and the environment. Technologies for leachate treatment, which were observed within the Scenario 1, included the hybrid wetland system, membrane bioreactor (MBR) and reverse osmosis (RO). The modeling results indicate the high removal efficiency of caffeine concentration (99.99%).","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"1 1","pages":"58-67"},"PeriodicalIF":0.2,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44518017","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}

Under the intuitive approach, the track was completely built by adapting to the terrain and environment in which it is located. The engineering approach to racing circuit development involves planning, designing, and building a car park at a specific location to accommodate all the users. Racing circuit design is based on recommendations depending on the type of race to be held. In Croatia, Croatian Car and Karting Federation issued the Circular Motor Racing Track Ordinance that defines the minimum requirements for organization and equipment of racing circuits. This paper presents a conceptual design of a racing circuit that is designed as per international requirements (FIA and FIM regulations) to host international sports events. This conceptual circuit is planned to be located in Osijek, which is the largest city in Eastern Croatia. It has a great location potential for becoming a motor sport center. The selected location has a possibility of venue extension for additional content, such as a test vehicle polygon, training center , and karting racing circuit. The conceptual design includes all the criteria, such as horizontal and vertical alignments, water drainage, pavement design, safety measures, and construction elements.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"10 1","pages":"98-107"},"PeriodicalIF":0.2,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44460298","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 sudden alteration to sediment regime and the sharp decreases of suspended sediment concentration (SSC) at the two gauging stations in the lower Drava River began in the 1980s. Suspended sediment load decreased about 65% between 1967–1981 (0.922×106 t/year) and 2003–2017 (0.323×106 t/year) for the Botovo station. For the Donji Miholjac station, suspended sediment load decreased about 81% between 1971–1981 (1.383×106 t/year) and 2007–2017 (0.263×106 t/year). The construction and operation of reservoirs were the main reasons for these sharp alterations. SSC and flow discharge (Q) relationships were assessed by proposing a new form of a sediment rating curve (SRC). Compared with the traditional SRC approach, the new form of the SRC can better capture seasonal dynamics of SSC at daily and monthly time-scales.","PeriodicalId":53887,"journal":{"name":"Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS","volume":"10 1","pages":"1-12"},"PeriodicalIF":0.2,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13167/2019.19.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47200237","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 absence of chemical admixtures in the concrete mixtures was because of the need to compare properly the properties of concretes with different cements without the influence of modifiers, which may result in different efficiencies for different types of binders. The concrete compositions of grades C20/25 and C30/35 were presented.

This paper presents a multi-criteria decision analysis to evaluate differen t waste management options and their applicability in small islands such as Vis. The results of this study indicate that the best food waste treatment option for small islands is discharging food waste into the city’s sewer system to be processed with wastewater through wastewater treatment.
