“…The International Organization for Standardization and the American Society for Testing and Materials classified AM into seven categories: vat photopolymerization, material jetting, binder jetting, material extrusion, powder bed fusion, sheet lamination, and directed energy deposition [146,147]. However, to date, the processes that are being used for applications in the construction industry include extrusion-based processes and binder jetting [148]. There are various applications of AM in the construction industry and there are even some records claiming different levels of success in printing buildings.…”

This paper presents a systematic review of Construction 4.0 in the context of the building information modeling (BIM) 4.0 premise. It comprises a review of the industry in the pre-fourth industrial revolution (4IR) age, the current and anticipated development of the 4IR, Construction 4.0’s origin and applications, and the synergy of its main drivers, i.e., the synergy of BIM with the internet of things (IoT) and big data (BD). The main aim of the paper is to determine the Construction 4.0 drivers and to what extent are they initialized by the 4IR, their development and their synergy with BIM, and the direction of BIM’s implementation in the construction phase. It was found that the main drivers of Construction 4.0, which originated from the 4IR, are BIM, IoT, and BD, but with specific implementations. The results of the analysis of BIM with IoT and/or BD revealed that the integrative approaches combining the aforementioned drivers show signs of project enhancement by providing significant benefits, such as improved real-time monitoring, data exchange and analysis, construction planning, and modeling. Furthermore, it was revealed that the main drivers are mostly applied in the project’s preconstruction phase, which is continuously developing and becoming more automated. The state-of-the-art review presented in this paper suggests that BIM is in transition, adopting Construction 4.0 to become BIM 4.0.

“…Recently, due to the development of novel materials and manufacturing processes, there has been an increasing need to utilize advanced manufacturing processes, materials and evaluate their mechanical behavior under extreme operating conditions [1,2]. Increasing interest has been observed to produce biodegradable materials for plenty of automotive parts rather than typically used glass, carbon, Kevlar, and other synthetic reinforcements that are hard to recycle [3,4].…”

Mechanical characterization of glass and jute fiber-based hybrid composites fabricated through compression molding technique

et al. 2021

Natural fibers, especially jute fibers, have gained interest in recent decades due to their attractive mechanical properties, high cellulose percentage, low cost, biodegradability, and easy availability. In the present study, flexural and drop weight impact behavior for different weight percentages of glass and jute fiber reinforced epoxy composites are studied experimentally according to ASTM standards. The hybrid composites were prepared through the compression molding technique. Numerical simulations were performed to investigate the predictive flexural response. The leading cause of error between experimental and numerical results is the manufacturing process and the reinforcement's woven nature. On the other hand, the impact strength was studied through drop weight testing at fixed 10 J energy. It is found that damage area decreases with increasing jute percentage in glass/jute hybrid composites, showing that jute fiber contributes more towards the composites' impact strength than glass fiber. Therefore, jute fiber can replace glass fiber in the glass/jute hybrid composite as a natural and eco-friendly constituent. The microscopic study reveals that the outer glass fiber layer helps minimize the stress distribution of jute fiber. A significant drawback of compression molding is the epoxy affluent areas in the composite.

This paper provides a state-of-the-art report on the up-to-date research on the emerging 3D concrete printing technology from the concrete materials perspective. It reviews the recent research focused on understanding and characterizing the rheological necessities of the concrete printing process and discusses how the researchers are tailoring compatible mix proportions for the 3D concrete printing process by using eco-friendly binders, waste aggregates, chemical admixtures, and nano-additives. This paper systematically evaluates anisotropic behavior in the mechanical properties of printed concrete and establishes an order for anisotropic behavior in the compressive, flexural, and tensile strengths along three different axes (X, Y, and Z axes) of printed concrete. It evaluates the ratio of flexural strength to the compressive strength of printed concrete along the above three axes. This article explains the influence of variation of printing process parameters on the mechanical properties and discusses reinforcement approaches used for increasing structural performance. The microstructure at the interface of adjacent layers and also at the interface of the reinforcement-cement matrix is discussed. The recent research on the durability performance of printed concrete is critically discussed and future research needs for 3D concrete printing are identified in this paper.
