Radiation-shielding concrete: A review of materials, performance, and the impact of radiation on concrete properties

Published in: Journal of Building Engineering

Nov 15, 2024

The efficiency of radiation shielding is crucial across industries having radioactive activities, from medical facilities to nuclear power stations. Radiation-Shielding Concrete (RSC) emerges as the preferred material for its cost-effectiveness, robust mechanical performance, ease of production, and excellent radiation attenuation properties against ionizing radiations such as gamma rays, X-rays, and neutrons. This comprehensive review delves into the evolution of SCI indexed research on concrete materials for radiation protection, focusing primarily on studies published in the last decade. It meticulously analyze the latest literature to understand how RSC materials enhance radiation attenuation. The review provides valuable insights into the influence of irradiation on both macro- and micro-properties, enriching the knowledge base for material efficiency and effectiveness concerning different types of radiation and shielding requirements. Additionally, this review with a set of recommendations for future research to advance progress in modern construction, encouraging further examination and innovation in the selection of RSC materials.

Response of Overhanging RC Beams Strengthened with Various Schemes of Externally Bonded CFRP Strips

Published in: Practice Periodical on Structural Design and Construction

Nov 01, 2024

This study evaluated the effectiveness of carbon fiber-reinforced polymer (CFRP) composites in strengthening RC beams for a simple span overhanging from both ends and subjected to equal concentrated forces at each end. This innovative loading configuration allows for investigating the performance of CFRP composites under pure moment within the middle span and ensuring continuity of the moment over the supports, which cannot be captured using the classical simple span with four-point loading configuration. A nonlinear finite-element analysis (NLFEA) using Abaqus software was carried out to accomplish the objectives of this study. The NLFEA models were verified initially based on independent experimental results from the literature to calibrate the NLFEA models in terms of the material constitutive models, boundary conditions, and meshing. Then 12 NLFEA models were created with different strengthening schemes of CFRP strips, varying in terms of length and number of layers, in addition to a control beam. All the evaluated RC beams were similar in terms of length and cross-sectional dimensions, material properties, and steel reinforcement. The results revealed that the developed NLFEA models can reasonably simulate the flexural behavior and failure mode of the studied RC beams, which are significantly affected by the configuration and length of the CFRP strips. The results also indicated that it is essential to extend the CFRP strips from the middle span toward the overhanging span to provide continuity and allow the CFRP strips to contribute effectively to the flexural strength.

Harmonizing smart technologies with building resilience and sustainable built environment systems

Published in: Results in Engineering

Jun 01, 2024

Given the escalating concerns posed by climate change-related disasters, there is an urgent need for a more sustainable and resilient built environment. The developing digital revolution in recent years has the potential to harness its superior features to achieve sustainable and resilient building sector goals. This paper aims to present a futuristic perspective on the three basic pillars of a more sustainable and resilient built environment. These pillars comprise sustainability, resilience, and the utilization of Artificial Intelligence (AI) for monitoring and managing structural health and performance. This is evident in the context of smart buildings and their ability to enhance energy consumption efficiency, improve quality of life, and strengthen structural health monitoring in terms of reducing damage and facilitating timely maintenance operations. Through comparing the components of the virtual city designed from two types of alkali-activated binder concrete (AABC) and ordinary Portland cement (OPC) concrete, all components of the city designed from AABC showed a reduction in the amount of emitted CO2. The highest decrease was observed in the schools designed from AABC, where the reduction was about 25 %, while the lowest decrease was for the villas and infrastructure; about 11 % and 10 % respectively, compared to those designed from OPC concrete. The results also indicated that the utilization of sustainable concrete instead of traditional varieties has the potential to decrease CO2 emissions by up to 25 %. The importance of this work resides in establishing a basis for forthcoming research that combines intelligent, environmentally friendly, and resilient building practices.

Towards increased adoption of furnace bottom ash as sustainable building materials: Characterization, standardization, and applications

Published in: Journal of Building Engineering

Apr 01, 2024

The global demand for coal is projected to increase in the current decade despite concerns regarding climate change, which will lead to an increasing volume of coal waste products such as furnace bottom ash (FBA). The effective use of alternative building materials such as FBA is important to meet various Sustainable Development Goals (SDGs), including SDG12&13 for Responsible Consumption and Production, and SDG9 for the promotion of sustainable industrialization and fostering innovation in infrastructure. This article aims to present a comprehensive review of the properties of FBA and its effect in cementitious composites in order to contribute to the development of relevant standards that frame, regulate, and encourage its usage as a sustainable and promising building material. The current article also provides an overview of the potential applications of FBA, as well as an extensive review of the crucial properties of FBA-based cementitious composites. It also covers the environmental benefits and cost feasibility related to using FBA as a sustainable building material. Finally, some obstacles to the recycling of FBA are highlighted, and gaps in the existing literature are identified, providing key directions for future research.

ANN-based critical review of the effective moment of inertia of RC beams

Published in: Emergent Materials

Jun 01, 2023

This paper presents an artificial neural network (ANN)–based critical review of the ACI 318 Code formula for calculating the effective moment of inertia (Ie) of reinforced concrete (RC) beams. The value of Ie varies along the span length from a gross cross-sectional moment of inertia (Ig) for uncracked sections to a cracked cross-sectional moment of inertia (Icr) for cracked sections. Branson’s expression for Ie was adopted by the ACI 318 Code until 2019 when a new equation for Ie was introduced in the most recent edition of the ACI 318–19 Code; however, the newly proposed modification requires further assessment. For that, the aim of this research is to propose a reasonable modification for estimating Ie based on the ANN technique considering various relevant parameters simultaneously that in turn will lead to more accurate calculation of the deflections of RC beams. Relevant data points were collected from various reputable experimental studies of RC beams and analyzed using the artificial neural network (ANN) technique. The collected data points entailed various parameters with potential influence on the value of Ie including the fibers’ volume fraction (Vf), concrete density, beam depth/width ratio, span length, applied moment (Ma), cracking moment (Mcr), and the values of Icr and Ig. A total of 657 data points were considered in the ANN training, testing, and verification processes. The results showed that the value of Ie noticeably increases with the increase in the Vf, concrete density, depth/width ratio, and Icr. Additionally, the influence of Mcr/Ma was more pronounced at a ratio of 0.5 rather than 2/3 as specified in the ACI-318–19 Code, which is included in the proposed modification to the ACI-318–19 Code.
