Design of Resilient Concrete Infrastructure for Corrosive Biogenic Environments

在现行的实务守则中，采用了一种规范性的方法来指定混凝土适用于不同的暴露环境。虽然这限制了供应链的创新和自由，但它仍然没有解决混凝土基础设施过早恶化的问题。通过以前的RCUK资助的项目，研究人员概述了一种基于性能的方法，用于含有海洋和除冰盐的常见暴露环境。该项目的目的是通过现场/实验室调查评估目前指定用于生物环境的混凝土的性能，并开发适合模拟此类环境的性能测试方法。生物源环境是指由于生物活动而导致的富含有害元素的暴露，如下水道管道，污水处理设施，厌氧发酵罐等。EPSRC相关研究领域：生物能源，建筑环境，能源网络，资源效率，弹性，整体能源系统

In the current codes of practice, a prescriptive approach is used for specifying concrete for different exposure environments. Whilst this restricts innovation and freedom at supply chain, it still does not address the premature deterioration of concrete infrastructure. Through previous RCUK funded projects, a performance-based methodology was outlined by the researchers for common exposure environments containing marine and de-icing salts. The aim of this project is to assess the performance of concretes currently specified for biogenic environments through site/laboratory investigations and develop a performance testing methodology suitable for mimicking such environments. Biogenic environments refer to exposures that are rich in harmful elements due to the biological activities, such as those in sewer pipes, sewage treatment facilities, anaerobic digestor, etc.EPSRC Related research areas: Bioenergy, Built Environment, Energy Networks, Resource Efficiency, Resilience, Whole Energy Systems
