Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.

The influence of granite cutting waste on the properties of ultra-high performance concrete [PDF]
This study analyzes the effect of using waste by-products generated in the process of granite cutting as part of the granular structure of Ultra High Performance Concrete (UHPC). The manufactured concrete has a compressive strength greater than 115 MPa.

Abstract Structural health monitoring (SHM) research generates vast amount of information, especially as unstructured data formats. To date, most natural language processing (NLP) applications focus on extracting information (syntactic or semantic level) rather than providing latent knowledge and generating newer information (pragmatic level).

Micromechanical modelling of self-healing cementitious materials [PDF]
A new approach is described for simulating self-healing behaviour in cementitious materials with a two phase micro-mechanical constitutive model. A Mori-Tanaka homogenisation scheme is employed for the composite along with an exterior point Eshelby ...

Effects of Steel and Polypropylene Fiber Addition on Interface Bond Strength between Normal Concrete Substrate andSelf-Compacting Concrete Topping [PDF]
Based on facts that the composite action in semi-precast and strengthened structural system depends on the bond strength of the interface between concrete faces of different ages, this preliminary research is aimed to investigate effects of mixed ...

Interface Shear Behavior of UHPC
To date, very little research has been conducted on the interface shear behavior of UHPC-class materials. The structural concrete research group at FHWA’s Turner-Fairbank Highway Research Center is currently developing an experimental program to evaluate the interface shear behavior of this class of materials.

Self-desiccation and self-desiccation shrinkage of silica fume-cement pastes [PDF]
Self-desiccation is one common phenomenon of high-performance cementitious materials, which are characterized by low water/binder (w/b) ratio and high mineral admixture incorporation. As a consequence, large magnitude of self-desiccation shrinkage, a key
