Radiological characterisation of alkali-activated construction materials containing red mud, fly ash and ground granulated blast-furnace slag
No full textPoor storage of industrial wastes has been a cause of land contamination issues. These wastes or by-products have the potential to be used as secondary raw materials in construction, promoting the concept of a circular economy that will avoid land contamination. Here we evaluate radiological environmental impacts when wastes that contain elevated levels of naturally occurring radionuclides (NORs) such as red mud, fly ash and ground granulated blast furnace slag are made into ‘green cements’ such as geopolymers or alkali-activated materials (AAMs). During the study, three AAM concrete and mortar series with various mixing ratios were prepared and investigated. The NOR content, I-Index, radon emanation and exhalation of the precursor waste materials and their cement products were measured and calculated and the strength of the cement products was compared. The emanation and the exhalation properties were calculated for the final products, weighing the data of the components as a function of their mixing ratio. The I-index alone suggested that the AAMs would be suitable products. AAMs containing ground granulated blast furnace slag exhibited the lowest radon exhalation and higher compressive strength, while the fly ash and red mud AAMs had increased final radon exhalation. In the case of fly ash, alkaline activation of fly ash dramatically increased the radon exhalation; the highest measured fly ash exhalation was 1.49 times of the theoretically calculated exhalation value. This highlights the increased risk of using fly ash as a component in AAMs and the need to carry out testing on the final products as well as individual secondary raw materials.</p

Early Shakespeare, 1588-1594
No full textEarly Shakespeare, 1588–1594 draws together leading scholars of text, performance, and theatre history to offer a rigorous re-appraisal of Shakespeare's early career. The contributors offer rich new critical insights into the theatrical and poetic context in which Shakespeare first wrote and his emergence as an author of note, while challenging traditional readings of his beginnings in the burgeoning theatre industry. Shakespeare's earliest works are treated on their own merit and in their own time without looking forward to Shakespeare's later achievements; contributors situate Shakespeare, in his twenties, in a very specific time, place, and cultural moment. The volume features essays about Shakespeare's early style, characterisation, and dramaturgy, together with analysis of his early co-authors, rivals, and influences (including Lyly, Spenser and Marlowe). This collection provides essential entry points to, and original readings of, the poet-dramatist's earliest extant writings and shines new light on his first activities as a professional author

Radiological evaluation of industrial residues for construction purposes correlated with their chemical properties
Full text linkThis is the author accepted manuscript. The final version is available from Elsevier via the DOI in this recordThis study characterises the naturally occurring radionuclide (NOR) contents of a suite of secondary raw materials or industrial residues that are normally disposed of in landfills or lagoons but now are increasingly used in green concretes. This includes ashes from a variety of industrial processes and red mud from aluminium production, as well as air pollution control residue and cement kiln dust. The chemical composition of the samples was determined with X-ray fluorescence spectroscopy (XRF). The Ra-226, Th-232 and K-40 activity concentrations were obtained by gamma spectrometry, and the results were compared with recently published NOR databases. The correlation between the NOR contents and the main chemical composition was investigated. The radioactive equilibrium in the U-238 chain was studied based on the determination of progeny isotopes. The most commonly used calculation methods (activity concentration index and radium equivalent concentration) were applied to classify the samples. The radon exhalation rate of the samples was measured, and the radon emanation coefficient was calculated. Significant correlation was found between the NORs and certain chemical components. The massic exhalation demonstrated a broad range, and it was found that the emanation coefficients were significantly lower in the case of the residues generated as a result of high-temperature combustion processes. The results showed a weak correlation between the Ra-226 concentration and the radon exhalation. This emphasises that managing the Ra-226 content of recycled material by itself is not sufficient to control the radon exhalation of recycled materials used in building products. The investigated parameters and their correlation behaviour could be used to source apportion materials found during the process of landfill mining and recovery of material for recycling.European Union Horizon 202
