Abstract

High-density concrete (HDC) has been extensively employed as radiation shielding owing to its high density and capacity to absorb gamma rays and neutrons. The optimal average density of HDC for protecting against various types of radiation generally ranges from 2.2 g/cm³ to 3.5 g/cm³. This density may vary depending on the type of aggregate used, such as serpentine, barite, siderite, magnesite, and others. The study analyzes the use of high density concrete as a radiation protector using systematic literature review. The research method uses the PRISMA methodology with data search using the Publish or Perish (PoP) application with the keywords "High-Density Concrete," "Materials," and "Radiation Shielding" on the Scopus database. Bibliometric analysis using VOSviewer visualizes relationships between key terms in research. The results show that the average optimal density on high density concrete for radiation protectors varies, depending on the type of aggregate used.The selection of aggregates has a significant impact on the performance of concrete in radiation protectors. Aggregates such as barite, hematite, magnetite, and industrial waste (such as CRT glass and EAF barrel) are effective in enhancing radiation protection performance. Overall, the compressive strength of high-density concrete is an important factor in ensuring structural stability and effectiveness as a radiation shield. This study provides an in-depth perspective on the development of high-density concrete as radiation shielding and offers directions for future research in this field.

Abstract

The development and advancement of digital technology, such as Digital Twin, providing real-time updates, and automation technologies like robotics, have been extensively explored in the construction industry. The capabilities of robotics, including enhanced safety features and the ability to perform tasks beyond human capacity, have led to widespread applications in design, construction management, autonomous transportation, and automated structural assembly. However, the limitations of robotics in adapting to changes on the field have prompted researchers to explore the integration of Digital Twin with robotics in the construction industry, aiming to enhance efficiency and safety for human workers. This research methodology is categorized into three stages: literature review, literature selection, and review process. The objective is to provide insights into the extent of Digital Twin and robotics utilization in the construction industry. The current integration of Digital Twin and robotics in ensuring workplace safety and fabrication tasks is still limited. Further research is needed to explore the application of Digital Twin and robotics in combination with other digital technologies such as AI, VR, IoT, and others. This holistic approach will contribute to the maximal development of these technologies. Abstrak Pengembangan dan kemajuan teknologi digital seperti Digital Twin yang dapat memberikan pembaruan waktu secara nyata. Teknologi otomasi seperti robotik juga sudah banyak dikembangkan untuk industri konstruksi, kemampuannya dalam memberikan keamanan dan membantu melakukan tugas-tugas diluar kapasitas manusia membuat robotik banyak diterapkan untuk desain, manajemen konstruksi, transportasi otonom, dan perakitan struktur otomatis. Keterbatasan robotik dalam menyesuaikan diri terhadap perubahan di lapangan, memberikan gagasan baru oleh para peneliti untuk mulai mengembangkan integrasi antara Digital Twin dengan robotik dalam industri konstruksi untuk memberikan kemudahan dan keamanan bagi manusia dalam melaksanakan pekerjaannya. Metode penelitian ini dikelompokkan menjadi tiga tahap: Pengambilan literatur, Pemilihan literatur, dan Proses peninjauan. Tujuannya adalah untuk mengidentifikasi makalah penelitian ini akan memberikan pandangan tentang sejauhmana penggunaan Digital Twin dan robotik untuk industri konstruksi. Pengembangan integrasi Digital Twin dan robotik masih sangat terbatas pengaplikasiannya pada keselamayan kerja dan pekerjaan fabrikasi. Perlu dilakukan penelitian lebih lanjut terkait dengan pengaplikasian Digital Twin dan robotik dengan adanya kombinasi terhadap tekologi digital seperti AI, VR, IoT dan lainnya , sehingga pengembangan teknologi tersebut dapat menjadi lebih maksimal.
