Moreover, green construction and sustainable waste managementpractices have adapted use of waste recycled materials for engineering purposes. This study explores the feasibility ofusing recycled construction and demolition waste and ground granulated blast furnace slag for developing shearstrength properties of bentonite clay. Direct shear tests were performed on specimens from bentonite and bentonite-stabiliser composites to evaluate the effect of both stabilisers under different curing times and percentages.Microanalyses were conducted to obtain microstructural, mineralogical and elemental composition of the stabilisedand unstabilised samples. Results exhibit that shear strength increased with increasing stabiliser percentages andcuring time, and the effects were more enhanced on higher stabiliser dosages and curing periods. Sample cohesionvalue increased from 58.90 kPa for pure bentonite sample to 67.26 kPa for the maximum additive percentages of 5%slag and 20%construction waste (sample S3G5), after 28 days of curing. The internal friction angle also increased by7.3° from the pure sample to the S3G5 bentonite-stabilisers composite specimen. Peak shear stress values alsoshowed a development of 55.95 kPa after additive induction and 28 days curing, for 200 kPa of normal stress. Curingperiod also affected the development of cohesion and peak shear strength of the stabilised samples. Internal frictionalangle for sample S3G5 also escalated by 2.3°, after 28 days, from the 25.0° value after sample curing of 1 day.Scanning Electron Microscopy (SEM) micrographs and Energy Dispersive Spectroscopy (EDS) spectra show thatstabilisers occupied vesicles and cracks found in construction waste particles, resulting in better particle interlockingmechanism and greater shear strength.SciVal Topic Prominence Topic: Prominence percentile: 81.105Reaxys Database InformationAuthor keywordsBentonite Recycled materials Shear strengthIndexed keywordsEngineeringcontrolled terms:Adhesion Blast furnaces Cements Curing Demolition Energy dispersive spectroscopyFriction Recycling Scanning electron microscopy Shear flow Shear strengthShear stress Slags Soil testing Strength of materials Waste managementEngineeringuncontrolled termsConstruction and demolition waste Energy dispersive spectroscopies (EDS)Ground granulated blast furnace slag Interlocking mechanisms Internal friction angleInternal frictional angles Recycled materials Sustainable waste management◅ Back to results ◅ Previous  ▻NextCSV export  Download  Print  E-mail  Save to PDF ⋆ Save to list  ▻More...View at PublisherJournal of GeoEngineeringVolume 11, Issue 2, 2016, Pages 59-73Hasan, U.a Chegenizadeh, A.a  Budihardjo, M.A.b Nikraz, H.a ab View references (23)Slags | Viscosity | TiO2 contentPlumX MetricsUsage, Captures, Mentions,Social Media and Citationsbeyond Scopus.Metrics 4 Citations in Scopus20th percentile1.00 Field-WeightedCitation ImpactCited by 4 documents,  , (2019) Journal of CleanerProduction,  ,(2018) E3S Web of Conferences,  , (2018) BuildingsInform me when this documentis cited in Scopus: Related documents,  ,(2016) Applied Clay Science  ▻View all metricsCritical review andmethodological issues inintegrated life-cycle analysis onroad networks Hasan, U.

It isbased on the idea that 'all citations are not createdequal'. SJR is a measure of scienti c in uence ofjournals that accounts for both the number of citationsreceived by a journal and the importance or prestige ofthe journals where such citations come from Itmeasures the scienti c in uence of the average articlein a journal it expresses how central to the globalCitations per documentThis indicator counts the number of citations received bydocuments from a journal and divides them by the totalnumber of documents published in that journal. Thechart shows the evolution of the average number oftimes documents published in a journal in the past two,three and four years have been cited in the current year.The two years line is equivalent to journal impact factor™ (Thomson Reuters) metric.Cites per document Year ValueCites / Doc.
