Performance of safety critical anchors in early age concrete with SCM

该项目旨在检查一系列水泥中锚杆的性能，以帮助制定新的安全和建筑指南。为了加快施工周期和提高生产率，需要在早期混凝土中安装和加载用于提升和连接混凝土构件的锚杆。然而，评估锚杆的最佳实践是基于成熟的混凝土。也有越来越多的补充胶凝材料的使用，但对锚杆的影响未知。该项目旨在应对建筑业的这一挑战。该项目计划通过试验和分析研究早期蠕变对锚杆安装的影响，以及影响混凝土中预埋式和后安装机械锚杆的滑移行为和极限性能的因素。其目的是，这些研究将提供新的设计指南。

This project aims to examine the performance of anchors in a range of cements, to contribute to new safety and building guidelines. Demands for faster construction cycles and increased productivity require anchors for lifting and joining concrete elements to be installed and loaded in early age concrete. Yet, best practice for evaluation of anchors is based on mature concrete. There is also increasing use of supplementary cementitious materials with unknown effects on anchors. This project aims to address this construction industry challenge. The project plans to study experimentally and analytically the effect of early age creep on anchor installation and the factors affecting the slip behaviour and ultimate performance of cast-in and post-installed mechanical anchors in concretes. It is intended that these studies will then inform new design guidelines.
