Traditional cement production emits approximately 1 ton of CO2 per ton of cement, which represents almost 80% of the total CO2 emissions of concrete and approximately 6% of the world’s emissions. Among supplementary cementitious materials, the use of agro-waste ash emerges due to its reduced CO2 emissions, chloride diffusion, and materials cost, in addition to its greater compressive strength. In Colombia, the disposal of agro-wastes, such as tobacco waste, is an environmental and economic concern. In this study, ash obtained from tobacco waste (TWA) was studied as a sustainable partial replacement for cement in hydraulic concrete. The TWA was reduced to a particle size of less than 75 μm and was characterized by X-ray florescence. A central composite design was used to study the influence of the ash replacement percentage of cement and the water/binder (w/b) ratio on the compressive strength at 28 days. The results show that it is possible to replace 10% of the cement with TWA using a 0.5 w/b ratio and obtain a 51% higher compressive strength than the control mixture at 28 days. Moreover, the experimental results demonstrated an improvement of 86% in the 7-day compressive strength when TWA was used.application/pdf10.1007/s40095-018-0272-x2008-91632251-6832https://repositorio.udes.edu.co/handle/001/3152engInternational Journal of Energy and Environmental EngineeringDerechos Reservados - Universidad de Santander, 2018info:eu-repo/semantics/openAccessAtribución-NoComercial 4.0 Internacional (CC BY-NC 4.0)https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf2https://link.springer.com/content/pdf/10.1007%2Fs40095-018-0272-x.pdfConcreteTobacco waste ashSupplementary cementitious materialSustainable construction materialCompressive strengthDesign of experimentsTobacco waste ash : A promising supplementary cementitious materialArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85PublicationTHUMBNAILTobacco waste ash. a promising supplementary cementitious material.pdf.jpgTobacco waste ash. a promising supplementary cementitious material.pdf.jpgGenerated Thumbnailimage/jpeg1793https://repositorio.udes.edu.co/bitstreams/fd07ac91-84dd-4fc9-8def-51ad72c466fe/download842183c4f1454d12b98f726b886a71efMD54Tobacco waste ash.
