Surface Finish in Metal Additive Manufacturing > ENGINEERING.com

Additive manufacturing (AM) can now produce high-quality parts in metal alloys. It is increasingly being used for structural aerospace applications. This is possible because, unlike with early metal AM processes, parts are now fully dense with few pores and gain structures often equivalent to a forged part. Powder bed fusion (PBF) processes are also able…

Effect of Using GFRP Reinforcement on the Behavior of Hollow-Core Circular Concrete Columns | Journal of Composites for Construction

Abstract Hollow-core concrete columns are widely used as structural members to reduce the cost and self-weight of concrete structures. This study investigates the axial load–axial deformation behavior of glass fiber-reinforced polymer (GFRP) bar- and helix-reinforced hollow-core circular concrete columns. Four specimens of 214-mm outer diameter and 56-mm circular inner hole diameter with a height of…

Peer Pressure in BIM-Based Collaboration Improves Student Learning | Journal of Civil Engineering Education

Abstract Building information modeling (BIM)-based collaboration may be associated with peer pressure in educational settings. Peer pressure creates a challenge for educators to foster students’ BIM skills and prepare them for a career in the architectural, engineering, and construction (AEC) industry. However, the effects of peer pressure on student learning in BIM classes remain unknown….

Creep and Long-Term Properties of Alkali-Activated Swedish-Slag Concrete | Journal of Materials in Civil Engineering

Fresh State Properties Fig. 3 shows the effect of activator type on workability and setting times, as discussed in a previous publication (Humad et al. 2018), and similar trends were also obtained by other researchers (Rajesh et al. 2013). The final setting times of Mixes SS10, SC10, and SC5+SS5 were 27, 43, and 52  h , respectively. Previous studies…

Fiber-Reinforced Polymer Bars for Concrete Structures: State-of-the-Practice in Australia | Journal of Composites for Construction

Abstract The harsh Australian environment makes the use of steel reinforcement in concrete structures problematic on account of corrosion. The probability of corrosion damage will significantly increase in the years to come and will become a major problem not only in coastal regions but also in inland parts of Australia due to increasing carbon dioxide…
