“…Overall, copper slag possesses a high percentage of heavy elements, such as iron and a high density, which is beneficial to RSC production. Slag from the smelting of lead and zinc ore, known as lead–zinc slag, has also been used in RSC [ 96 , 97 ]. Lead–zinc has a high percentage of nickel at 59.09%, while other elements such as Fe, Al, and Mg are at 11.22%, 6.19%, and 3.48%, respectively [ 97 ].…”

Nuclear energy offers a wide range of applications, which include power generation, X-ray imaging, and non-destructive tests, in many economic sectors. However, such applications come with the risk of harmful radiation, thereby requiring shielding to prevent harmful effects on the surrounding environment and users. Concrete has long been used as part of structures in nuclear power plants, X-ray imaging rooms, and radioactive storage. The direction of recent research is headed toward concrete’s ability in attenuating harmful energy radiated from nuclear sources through various alterations to its composition. Radiation shielding concrete (RSC) is a composite-based concrete that was developed in the last few years with heavy natural aggregates such as magnetite or barites. RSC is deemed a superior alternative to many types of traditional normal concrete in terms of shielding against the harmful radiation, and being economical and moldable. Given the merits of RSCs, this article presents a comprehensive review on the subject, considering the classifications, alternative materials, design additives, and type of heavy aggregates used. This literature review also provides critical reviews on RSC performance in terms of radiation shielding characteristics, mechanical strength, and durability. In addition, this work extensively reviews the trends of development research toward a broad understanding of the application possibilities of RSC as an advanced concrete product for producing a robust and green concrete composite for the construction of radiation shielding facilities as a better solution for protection from sources of radiation. Furthermore, this critical review provides a view of the progress made on RSCs and proposes avenues for future research on this hotspot research topic.

“…Steel mill scale has the capacity to be evaluated as a substitute for river sand in concrete. Different experiments on consumption of this steel mill scale waste from iron industry have been conducted in concrete on its partial substitution for fine aggregates [10]. Mechanical strength properties produce better results for the concrete contains coarse steel mill scale aggregate [11].…”

In the current research work steel mill scales, waste from steel industries has been tested out as a fractional replacement for sand. Steel mill scale is a waste product obtained from the steel production industries and it has an adverse effect on the environment. Steel mill scale has become a good substitute for fine aggregates in the construction industry. The experimental parameter was the percentage of steel mill scale substitution (0%, 20%, 40%, 60%, 80% and 100%) by weight to fine aggregate content in M30 grade concrete and the results obtained from those mixes are compared with original M30 grade concrete. Compressive strength, split tensile strength, flexural strength and micro-structural characters of such concrete were evaluated. The interaction of steel mill scale within the concrete has been methodically investigated using micro-structural studies. It was found that very small particle size of steel mill scale fills the voids between the fine and coarse aggregate thus makes dense concrete. The test outcomes suggest that recycling steel mill scale by utilizing as a fractional replacement for fine aggregate offers a viable cost effective and environmentally friendly solution at 60% replacement.

This article is devoted to the study of determination of gamma radiation shielding efficiency by new radiation-resistant glasses of the 0.5TeO2-(0.5-x)Bi2O3-xWO3 type. As a method of obtaining glasses, the method of solid-phase synthesis combined with thermal annealing and subsequent hardening was used. The amorphous nature of the synthesized samples was confirmed by X-ray phase analysis. Determination of the shielding efficiency, as well as the effect of Bi2O3 and WO3 content in the glass composition on the attenuation efficiency was carried out by evaluation of gamma radiation intensities from the 137Cs source, with a gamma ray energy of 661 keV. The evaluation was performed on parameters such as radiation protection efficiency, linear and mass attenuation coefficients, half-value layer and mean free path. During the studies, it was found that glasses of the following composition 0.5TeO2-0.1Bi2O3-0.4WO3 are most effective, which are 1.3-2 times higher than those of the composition 0.5TeO2-0.4Bi2O3-0.1WO3.
