De plus, les ciments CSA presentent des caracteristiques ecologiques associees a leur production, notamment une reduction de l'empreinte CO2. Le comportement expansif des ciments CSA est principalement controle par la quantite de la phase ettringite, cette derniere est produite lors de l’hydratation de la phase importante, la ye’elimite [Ca4 (Al6O12)SO4]. Cette these presente, d’une part, les conditions optimales pour la synthese de la phase ye’elimite la plus pure possible par des reactions a l’etat solide, et d’autre part, une description fondamentale des mecanismes de formation de cette phase. Un autre aspect de ce travail vise a etudier l’influence de la finesse et de l’addition d’acide citrique sur la dissolution de la phase ye’elimite. Pour l’etude de l’effet de la finesse, une poudre fine et pure de ye’elimite a ete synthetisee par des methodes sol-gel, ces dernieres methodes de synthese ont ete developpees d’une maniere originale dans notre these. Plusieurs techniques experimentales ont ete realisees pour mener a bien les differents aspects de la presente these, a savoir l'analyse quantitative par DRX (methode Rietveld), l’analyse thermique (ATG, ATD, et dilatometrie), MEB (imagerie en retrodiffuse et cartographie EDS), l’analyse BET, l’analyse granulometrique par diffraction laser, et l’analyse d'images (porosite 2D et analyse granulometrique 2D).","PeriodicalId":282577,"journal":{"name":"SP-349: 11th ACI/RILEM International Conference on Cementitious Materials and Alternative Binders for Sustainable Concrete","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122007492","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}

Various sources of glass were used including soda glass, e-glass and Pyrex glass. All the materials showed excellent pozzolanic activity when ground to pass 75-microns. The use of ground glass resulted in substantial reductions in permeability and chloride penetrability, and improved resistance to sulfate attack. Air-entrained concrete containing glass showed good freeze-thaw resistance. E-glass and borosilicate glass were effective in preventing deleterious expansion due to alkali-silica reaction (ASR). Bottle glass, which contains substantial amounts of alkali, was not efficacious with regards to ASR. The inclusion of bottle glass results in very substantial increases to the pore solution alkalinity and this can result in substantial increases in expansion in concrete containing reactive aggregate and low-alkali cement. It is shown that the accelerated mortar bar test is not suitable for evaluating the impact of high-alkali materials on ASR as the alkalis contributed by the cementing materials are released when the mortar bars are masked by the conditions of the test (first immersed in hot water and then in hot NaOH solution).","PeriodicalId":282577,"journal":{"name":"SP-349: 11th ACI/RILEM International Conference on Cementitious Materials and Alternative Binders for Sustainable Concrete","volume":"128 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132804937","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}
