A Comparative Analysis of the Rebound Hammer and Ultrasonic Pulse Velocity in Testing Concrete

Nigerian Journal of Technology, 2012
This work presents a study on the comparison between some non-destructive testing tech-niques (Rebound Hammer and Ultrasonic Pulse Velocity). Tests were performed to com-pare the accuracy between the rebound hammer and the ultrasonic pulse velocity methodin estimating the strength of concrete.

Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

Assessing the Aged Prestress Concrete Girder’s Quality in Al-Rayhanna Bridge Using NDT

Journal of Engineering
Many of the Iraqi highway bridges (especially in Anbar Province) are in poor condition even after they have been checked and determined to satisfy acceptable standards due to the effect of many risk factors. These risks are related to factors such as the

Advances in rebound hammer mechanical testing for concrete material strength assessment: Intelligent sensing fusion and arid-cold region application

Journal of Physics, Conference Series
The rebound hammer test serves as a fundamental mechanical non-destructive testing (NDT) technique for the in-situ evaluation of concrete compressive strength, which is critical for material performance characterization in civil engineering.

Reclaimed Well Sites on Salt Affected Soils: Electrical Conductivity and Sodium Adsorption Ratio as Plant Community Response Indicators

Land Degradation &Development, EarlyView.
ABSTRACT Salt affected soils are common worldwide, resulting from natural causes and anthropogenic activities. Saline and sodic soils often occur in association with oil and gas production, impacting soil properties which can impede vegetation growth and development.

Integrating X‐Ray Computed Tomography and Hydraulic Properties for Soil Quality Assessment Under Soil Compaction

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction poses a significant threat to soil quality and sustainability, necessitating advanced assessment methods. We hypothesized that incorporating x‐ray computed tomography (XCT)‐derived pore characteristics with hydraulic properties would significantly enhance the development of a soil quality index (SQI) under soil compaction ...

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Prediction of Concrete Compressive Strength Based on Gradient-Boosting ABC Algorithm and Point Density Correction

Eng
Accurate prediction of concrete compressive strength is essential for ensuring structural safety in civil engineering, particularly in road and bridge construction, where inadequate strength can lead to deformation, cracking, or collapse. Traditional non-

Localization Through Coordination? Implementing the Humanitarian‐Development‐Peace Nexus in the Democratic Republic of the Congo

Public Administration and Development, EarlyView.
ABSTRACT As a global concept and initiative, the Humanitarian‐Development‐Peace Nexus (HDPN) aims to improve integration across the traditionally siloed humanitarian, development, and security sectors, while foregrounding the involvement of local actors.
