This paper proposes an optimal design method for low-carbon concrete containing fly ash and limestone powder. This design method considers the influence of strength (30, 40, and 50 MPa) and carbonization service life (50 and 100 years). The genetic algorithm was utilized to determine the optimal global solution, which satisfies different constraints and can find the decisive factor of the concrete mixture design. The analytical results are as follows: When the carbonization service life is 50 years, for ordinary-strength concrete (30 MPa), carbonation durability is the decisive factor in the mixture design, while for medium-(40 MPa) and high-strength (50 MPa) concrete, strength is the decisive factor. When the carbonation service life is 100 years, for ordinary- (30 MPa) and medium-strength (40 MPa) concrete, carbonation durability is the decisive factor for the mixture design, while for high-strength (50 MPa) concrete, compressive strength is the decisive factor. Furthermore, the CO2 emissions, compressive strength, and water–binder ratio of the optimized concrete design results are in line with the actual project, which proves the effectiveness of the proposed method.","PeriodicalId":9857,"journal":{"name":"Ceramics-silikaty","volume":"13 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87813740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chloride concentration was measured using the potentiometric method, and the Ca(OH) 2 content in the CAC was calculated using the thermogravimetric method. The results show that the chloride concentration in the submerged zone decreases with an increasing erosion depth; meanwhile, in the tidal and salt spray zones, the chloride concentration showed a two-stage distribution pattern. The depth of the convective zone gradually increases with an increasing erosion time, and the depth of the convective zone in the salt spray zone is larger than that in the tidal zone. The chloride diffusion coefficient exhibits a power-function attenuation relationship with erosion time when exposed to different corrosion zones. The attenuation coefficient of the chloride diffusion coefficient increases with an increasing FA content. Moreover, the attenuation coefficient is the highest in the salt spray zone with it being 10.8 % to 28.5 % higher than that of the tidal zone. In addition, the Ca(OH) 2 content in the tidal zone is not only the lowest, but also gradually decreases with an increasing erosion time.","PeriodicalId":9857,"journal":{"name":"Ceramics-silikaty","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82233035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
