Prismatic specimens were molded, cured at 65 °C and 85 °C and submitted to flexural and compressive strength tests. Unreacted fly ash and geopolymers were characterized by X-ray diffraction and thermogravimetric analysis. In general, the mechanical strength was enhanced by increasing the molar concentration and the curing temperature. This trend was confirmed by thermogravimetric data. However, for a lower amount of NaOH there were no significant differences between the strength results. The mixture with the highest strength was obtained with the 16 M NaOH solution and curing temperature of 85 °C, which resulted in flexural strength of 4.20 MPa, compressive strength of 21.35 MPa and also the highest weight loss of 9.89%.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Effect_of_NaOH_concentration_and_curing_regime_on_geopolymer/5862075","contentUrl":null,"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":0,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2018-02-07T02:54:29.000Z","registered":"2018-02-07T02:54:29.000Z","published":"2018","updated":"2020-08-30T18:02:04.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id":"10.6084/m9.figshare.5862075","type":"media"}},"references":{"data":[]},"citations":{"data":[]},"parts":{"data":[]},"partOf":{"data":[]},"versions":{"data":[]},"versionOf":{"data":[]}}}}
