Reinforcement of Cement Stabilized Macadam

Image
                                       INTRODUCTION Cement stabilized macadam (CSM) serves as a critical semi-rigid base layer in Chinese highway pavement structures. Over time, environmental factors and traffic loads contribute to cracking, reducing its service life. Despite the widespread use of CSM, limited studies have examined the performance of repaired specimens. Understanding the fracture behavior and damage evolution of CSM after repair is essential for improving pavement durability. This study investigates these aspects using experimental and microscopic methods to enhance repair strategies and performance evaluation. LITERATURE BACKGROUND Previous research highlights the vulnerability of CSM to cracking due to cyclic loading and environmental impacts. Traditional studies focused mainly on initial damage rather than post-repair behavior. Repair methods, such as the application...

Legacy of Austro-Hungarian Military Buildings in Banja Luka #ArchitectureHistory

Image
  Introduction The architectural and urban evolution of Banja Luka, Bosnia and Herzegovina, is deeply intertwined with its Austro-Hungarian past, particularly through the transformation of former military structures. These buildings, initially erected between 1878 and 1918 for administrative, residential, healthcare, and logistical purposes, played a crucial role in shaping the city’s physical and cultural identity. This paper explores the processes of replanning, reconstruction, and rebranding that have redefined these structures across different historical phases. By analyzing the continuity and change in the architectural function and meaning of these edifices, the study reveals how military heritage has been adaptively integrated into modern urban life. The research combines archival investigation with contemporary field observations, providing insight into the evolving relationship between built heritage and socio-political transformations. The introduction establishes the st...

CO2 Impact on Steel Slag Materials | #CarbonCapture

Image
Introduction Steel slag, a by-product generated during steel manufacturing, poses significant environmental challenges due to its disposal issues. However, it also presents an opportunity for carbon utilization through carbonation curing. By exposing steel slag to carbon dioxide, its properties can be enhanced while simultaneously reducing CO2 emissions. This study explores how varying CO2 concentrations influence the curing process, focusing on the carbon uptake, mechanical strength, and microstructural transformations of compact steel slag. The investigation aims to optimize the use of industrial flue gas as a sustainable means of CO2 sequestration and material strengthening. Experimental Design and CO2 Concentration Range The research examined a broad spectrum of CO2 concentrations, ranging from 0.04% (representing ambient atmospheric levels) to 27% (simulating industrial flue gas conditions). Compact steel slag samples were subjected to these environments for carbonation curing. Th...

Bridge Health Monitoring #SHM

Image
  Introduction Bridges play a pivotal role in ensuring national mobility and supporting economic activity, making their structural health a critical concern. Structural health monitoring (SHM) systems are essential for maintaining bridge safety and durability. However, sensor faults, environmental noise, and transmission issues can compromise the quality of SHM data. To mitigate these challenges, anomaly detection methods are widely employed. Despite their popularity, there is no comprehensive evaluation comparing these techniques. This review addresses that gap by systematically analyzing recent research in SHM anomaly detection. Motivation and Research Gap Existing reviews on bridge SHM anomaly detection are limited in scope and often fail to synthesize comparative insights. Most studies overlook real-time performance and multivariate data analysis, which are crucial for practical deployment. Moreover, previous work rarely provides a structured framework to classify detection ...
