Results revealedecological zonation taking into account the taxonomic richness and the relative abundance of different zoological groups, and allowed distinguishing abundant, ubiquitous and permanent taxa as well as the existence of a spatiotemporal faunistic gradient. These preliminary results allowed highlightingtaxonomically the “upstream invertebrate fauna”, the “ubiquitous invertebrate fauna” and the “downstream invertebrate fauna”. Consequently, it appearedthat Plecoptera, Hemiptera, Coleoptera are characteristic to the upstream area during the whole year in most of the sampling sites, whereas Diptera, Oligochaeta and Hydracarina are more abundant in the downstream area but in less density in the middle stream. On the other hand, the longitudinal evolution approach was considered in order to evaluate the inter-site distribution. According to the trophic levels, the classification between the various communities was investigated taking into account the concepts of the \"Food Functional Group\" and \"The River Continuum Concept\".","PeriodicalId":31081,"journal":{"name":"Lebanese Science Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48840160","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}

To overcome it, it will be necessary to ensure a rational exploitation of the aggregates available to the country by aevaluation of the existingresources. According to the statistics, the glass wastes accounted for 7% of the world’s solid wastes. The glass wastes can be used in concrete production in two forms: replacing part of aggregate or using as supplementary cementmaterial to replace cement. Using glass wastes to produce recycled aggregates for the production of new concrete reduces the consumption of natural resources as well as landfills.This work consists in formulating a micro-concrete with a substitution of 5 to 25% by weight of crushed calcareous aggregates of fraction 3/8 by glass aggregates of the same fraction 3/8. The incorporation of glass wastes as an aggregate in the micro-concrete plays a role of skeleton and improves its compressive mechanical strength.The compressive strength is considerably improved by substitution of crushed calcareous aggregates by recycled glass aggregates. The optimum has been reached for a value of around 46 MPa for a substitution of 10% of crushed limestone aggregates. The substitution of 10% crushed gravel by crushed glass allows improving the strength of more than 27%.The results obtained provedthat waste glass can be used as an aggregate for producing micro-concrete with a relatively high strength which will not deteriorate with time.","PeriodicalId":31081,"journal":{"name":"Lebanese Science Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45621895","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}
