“…It also assists in the improvement of the adhesion of the matrix and fibre. It was reported by Ochbelagh et al [32] that the microstructures of gamma irradiated samples had changed and they were more compressed than the non-irradiated samples. Meaning that the gamma ray removed the micro-pores within the samples, which that demonstrated by scanning electron microscopy (SEM), as well as, the compressive strength was also enhanced.…”

In recent decades, researchers have used plastic to replace natural aggregates (NAs), or as filler and fibre within the concrete. This particular paper puts forward a review that gives comprehensive consideration to the properties and drawbacks, of concrete that contains plastic. As such, it may be hypothesised that poor bond capacity and higher air content due to inclusion of plastic aggregate (PA) within concrete are the predominant factors that reduce the properties in terms of mechanics and durability. In that regard, this study has put forward a new method of curing using microwave irradiation for improvement with respect to those factors. So, that there can be further improvement with regard to overall durability with respect to advanced chemical and hydrophobic resistivity and enhanced performance for conventional concrete with respect to bonding and ductility.

Beton, bulunduğumuz yüzyılın en yaygın kullanılan yapı malzemesidir. Ağır beton ise özel üretilmiş bir beton çeşididir ve birim hacim ağırlığı yüksek olan betonları tanımlamaktadır. Ağır beton üretimi için ağır agregaların kullanılması gerekmektedir. Teknolojinin ilerlemesi ve artan insan nüfusu ile insanlar, radyoaktif ışın ve dalgalara daha çok maruz kalmaktadır. Üretilecek özel yapı malzemeleri ile bu etkiden kaçınmak mümkündür. Ağır betonlar bu tür ışınlara karşı oluşturdukları zırh etkisi ile canlıları korur. Hali hazırda birçok hastane ve askeri birimlerde kullanılan ağır betonlar üretimi kolay ve kesin çözüm sunan bir yöntemdir. Özellikle nükleer çalışmaların hız kazandığı bu dönemde, ağır betonlar yüksek birim ağırlıkları nedeniyle olası patlama, ışın yayınımı, ayrıca yüksek sıcaklık ve ses etkisinden yüksek korunma sağlar. Bu çalışmanın amacı son yıllarda ağır beton ve ultra yüksek dayanımlı ağır beton ile ilgili yapılan çalışmalardaki gelişmeleri takip etmektir. Arama indekslerinde yakın tarihli yapılan literatür araştırması sonucunda ağır betonlar ile ilgili genel bir bakış açısı sunan çalışmaya rastlanmamıştır. Literatürdeki bu eksiğin kapatılması adına bu çalışmanın yapılmasına ihtiyaç duyulmuştur.

“…This type of radiation is an electromagnetic radiation that is similar to X-rays but at shorter wavelengths [ 55 ]. The high intrusion of gamma rays is further demonstrated through the solidification and removal of micropores in the concrete’s microstructure after 7 days of exposure to a gamma source [ 104 ]. The efficiency of RSC in attenuating gamma rays is measured based on the linear attenuation coefficient.…”

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.
