Recycled powder as filler admixture in cementitious systems : production and characterization [PDF]
, 2016 In concrete production, aggregate represents almost 75% of the materials used. The exploitation of natural sources for this purpose also causes an environmental impact, while deposition of wastes from construction industry pollutes soil and water.

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.

Making Good Sense: Pragmatism's Mastery of Meaning, Truth, and Workable Rule of Law [PDF]
The hermeneutic pragmatism explored in this article timely examines how “post-truth” claims over-estimate semantic freedoms while at the same time underestimating semantic and pre-semantic restraints.

Assessment of the factor κk,max in classification of steel fiber‐reinforced concrete
Structural Concrete, EarlyView.Abstract This paper presents a general approach, and results employed in a study aimed at assessing the value of a coefficient, κk,max, introduced in Annex L in EN 1992‐1‐1:2023 (EC2). This coefficient defines an upper limit of the ratio between steel fiber reinforced concrete (SFRC) characteristic and mean values of the residual tensile strengths, fR1

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate
Structural Concrete, EarlyView.Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Structural Concrete, EarlyView.Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...
