Enhancing printability of 3D printed concrete by using metakaolin and silica fume

Structural Concrete, EarlyView.
Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Computer-aided analysis and design of the shape rolling process for producing turbine engine airfoils [PDF]

Mild steel (AISI 1018) was selected as model cold-rolling material and Ti-6Al-4V and INCONEL 718 were selected as typical hot-rolling and cold-rolling alloys, respectively.

Experimental study on the impact of traffic‐induced vibrations on early‐age concrete

Structural Concrete, EarlyView.
Abstract The COUNT (Concreting under Traffic) research project systematically examined the effects of traffic‐induced vibrations on early‐age, hardening concrete—a critical issue for bridge construction and renovation. Traffic closures are often imposed during such projects to mitigate potential damage from vibrations.

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

The behaviour of a two-component backfilling grout used in a Tunnel-Boring Machine [PDF]

, 2011
The instantaneous filling of the annulus that is created behind the segment lining at the end of the tail during the TBM advance is an operation of paramount importance.

Utilization of cellulose nanocrystal as a bio‐based material and nanosilica in cement‐based systems: A comparative study

Structural Concrete, EarlyView.
Abstract Cellulose nanocrystals (CNCs), increasingly utilized in cement‐bound materials, offer improved material properties and enhanced sustainability due to their bio‐based origin. Nanosilica (NS), known for its high reactivity and refinement of cement microstructure, also significantly impacts cement performance.
