Results indicated that temperature and time of carbon curing have a substantial impact on the carbonation process. When the curing temperature increased, the structure, size, and quantity of calcium carbonate polymorphs, as well as their decomposition temperature alter. Vaterite is easier to form when cured at a temperature of 1 °C. Furthermore, although the carbonation process is separated into two stages, it is primarily regulated kinetically by product layer diffusion with an activation energy of about 51.9 kJ/mol. Temperature influences not only the microstructure and reaction process but also the compressive strength and carbonation products, which follow a particular rule as the temperature changes. This research has significant implications for the enhancement of early strength and construction efficiency of building materials in low-temperature environments.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"1 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41619540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, the source and characterization of AD are introduced, and the differences between primary aluminum dross (PAD) and secondary aluminum dross (SAD) are analyzed. Then, the harmless treatment and utilization of AD are studied. Relative to the mature PAD recycling industry, the treatment of SAD is still in the small-scale experimental stage. The pyrometallurgical and hydrometallurgical routes are discussed as SAD processing methods, and the removal rate of hazardous content of SAD can reach 90%. Based on the high removal rate, high-purity Al, Al2O3, and other products can be prepared from SAD. Certain products, such as foaming materials, refractory materials, admixtures, and aluminum hydroxide gel material can be prepared by SAD. Finally, the economic and environmental values of the treatment and utilization of SAD are discussed. The environmental and economic assessment of SAD treatment behaves well in both life cycle assessment and life cycle cost calculations. A comprehensive display of SAD lifecycle treatment may promote the sustainable development of the aluminum industry.

This study demonstrated that UHPC containing HPS showed a lower viscosity and yield stress and developed higher compressive strength and flowability than that of UHPC with SF. Furthermore, the HPS with higher pozzolanic activity consumed calcium hydroxide crystals and formed C-S-H gel, which refined the pore structure, improved the compressive strength, and decreased the porosity. Moreover, HPS changed the gel molecular structure, increased the Al substitution in the silicate network and mean chain length of C-(A)-S-H, and deceased Ca2p-Si2p energy separation values, which led to a higher degree of polymerization in the C-(A)-S-H.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1399 - 1413"},"PeriodicalIF":4.4,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48464867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of laboratory tests were carried out to study effects of different activator concentrations (i.e. 1, 2, and 3 mol/L) and temperatures (i.e. 20, 30, and 40 °C) on time-dependent rheological properties (i.e. yield stress, apparent viscosity, and thixotropy) of AAS paste, which was made from ground granulated blast furnace slag (GGBS) and sodium hydroxide activator. The temporal variations in hydration process of AAS paste were examined and analyzed using X-ray diffraction (XRD) and scanning electron microscope (SEM). Moreover, the plugging effect of AAS paste was investigated by tunnel leakage plugging test. The test results indicate that the shearing behavior of AAS paste could reasonably be described by Bingham plastic model. There was a great increase in yield stress, apparent viscosity, and thixotropy of AAS paste with an increase in activator concentration and temperature. The increase in those rheological properties were mainly attributed to the rapid formation of C-S-H gels and aluminum hydroxide magnesium at a higher concentration level and temperature. In addition, a power function was proposed to fit the time-dependent apparent viscosity, which enabled the explicit quantification of activation energy, i.e. the minimum energy required to initiate the hydration of AAS paste. In leakage plugging test, the characteristic of decreasing with the increase of exciter concentration and temperature was seen in both the point of water pressure and the time required to reach 0.5 MPa sealing water pressure.","PeriodicalId":48521,"journal":{"name":"Journal of Sustainable Cement-Based Materials","volume":"12 1","pages":"1360 - 1375"},"PeriodicalIF":4.4,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42531747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
