在2024年12月1日于江苏大学举办的江苏高校首届外国留学研究生学术交流研讨会中,西交利物浦大学设计学院的一名斯里兰卡博士生Dhanushka Kobbekaduwa荣获学术论文奖一等奖。

At the First Jiangsu Foreign Postgraduate Research Symposium held at Jiangsu University on 1 December 2024, Dhanushka Kobbekaduwa, a Sri Lankan PhD student from Xi’an Jiaotong-Liverpool University’s Design School, won the First Prize for the Outstanding Academic Paper Award.

研讨会以“创新·学术之本”为主题,通过主旨演讲、墙报展示和分论坛汇报,为外国留学研究生们提供了一次宝贵的交流和学习机会。研讨会汇聚了来自省内23所高校的近百名外国留学研究生,共有12名学生获得学术论文奖一等奖。

Dhanushka是一名土木工程三年级博士生,他在获奖论文《Effect of Organic Corrosion Inhibitors on the Void Content Properties of Repair Mortars》中探索了如何提高混凝土结构的耐久性和可持续性。

With the theme of “Innovation: The Foundation of Academia”, the symposium provided an excellent opportunity for international postgraduate students to communicate with peer researchers through keynote speeches, poster presentations, and oral presentations. Nearly 100 international postgraduate students from 23 universities across Jiangsu province participated in the symposium, with 12 of them selected as first prize.

As a Year Three civil engineering PhD student, Kobbekaduwa explores how to improve the durability and sustainability of concrete structures in his awarded paper “Effect of Organic Corrosion Inhibitors on the Void Content Properties of Repair Mortars”.

开发更耐用的混凝土结构
Developing more durable concrete

作为现代土木工程的支柱材料,混凝土广泛应用于全球先进基础设施。然而,钢筋混凝土结构因耐久性问题,尤其是钢筋锈蚀,已成为备受关注的全球挑战。钢筋锈蚀会削弱钢筋与混凝土之间的粘结力,导致结构完整性下降、维修成本高昂和潜在安全风险。

Dhanushka说:“作为一个对土木工程和建筑充满热情的人,我一直对混凝土技术的应用及其创新潜力感到着迷。”

他的研究项目利用添加了有机缓蚀剂的修补砂浆来解决锈蚀问题。这种砂浆可以降低钢筋锈蚀速度,从而提高修补结构的耐久性和性能。

Concrete, a material that forms the backbone of modern civil engineering, is being used by sophisticated infrastructure at every corner of the modern world.

However, the deterioration of reinforced concrete structures due to durability challenges, particularly reinforcement corrosion, has become a significant global concern. Corrosion weakens the bond between steel reinforcement and concrete, leading to structural integrity issues, costly repairs, and safety risks.

“As someone deeply passionate about civil engineering and construction, I have always been fascinated by the applications of concrete technology and its potential for innovation,” says Kobbekaduwa.

His project focuses on a solution to the corrosion problem by utilising repair mortars enhanced with organic corrosion inhibitors, which reduce the rate of reinforcement corrosion, thereby improving the durability and performance of repaired structures.

Dhanushka解释道:“我的项目将改性修补砂浆与纺织品加固砂浆(TRM)系统相结合,这是一种十分有前景的复合材料,以卓越的机械性能裂缝控制能力而闻名。

“TRM作为一种外部加固系统,可提高承载能力,同时减轻环境暴露造成的进一步损害。”

他补充说,通过对这些创新材料及其应用的了解,该项目有助于开发经济高效、耐用的解决方案,助力全球混凝土结构的修复和改造。

Kobbekaduwa explains: “My project combines the modified repair mortars with textile-reinforced mortar (TRM) systems, a promising composite material known for its superior mechanical properties and effective crack control.

“TRM is applied as an external strengthening system to improve load-bearing capacity while mitigating further damage caused by environmental exposure.”

By advancing the understanding of these innovative materials and their applications, the project contributes to developing cost-effective and durable solutions for repairing and retrofitting concrete structures worldwide, he adds.

在西浦从事研究
Pursuing research at XJTLU

Dhanushka认为,西浦为他提供了一个探索兴趣和实现目标的理想平台。

他说:“西浦拥有先进的实验室设施、一流的资源和敬业的教职员工团队,为进行研究提供了良好的支持。

“在这里,我可以与土木工程领域的知名博士生导师共事,他们帮助我聚焦研究方向,培养完成研究的必要技能。”

Kobbekaduwa credits XJTLU for providing the ideal platform to explore his interests and achieve his goals.

“With its advanced laboratory facilities, state-of-the-art resources, and a team of dedicated academic staff, XJTLU offers a supportive environment for research.

“I get to work with renowned PhD supervisors who are experts in civil engineering, and help me refine my research focus and develop necessary skills for successful research,” he says.

对Dhanushka来说,参加本次研讨会是一次收获颇丰的经历。他指出,参与来自不同学科的研究生的研究报告,不仅拓宽了他的研究视野,也提供了全新的视角。

“这也是一个很好的交流平台,让我能够与来自不同大学的同学和学术人员建立联系。

“我非常感谢我的导师团队,Ominda Nanayakkara博士、Theofanis Krevaikas博士和Luigi Di Sarno博士,感谢他们在我攻读博士学位期间给予我的支持和指导。”他说。

To Kobbekaduwa, participating in the research symposium has been a rewarding experience, allowing him to engage in research presentations from postgraduate students across diverse disciplines, which helps broaden his research insights and offered fresh perspectives for his work.

“It was also an excellent platform for networking, enabling me to connect with fellow students and academic staff from various universities.

“I am grateful to my supervisory team, Dr Ominda Nanayakkara, Dr Theofanis Krevaikas, and Dr Luigi Di Sarno, for their continuous support and guidance throughout my PhD journey,” he adds.
