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.

该项目旨在检查锚在一系列水泥中的性能，以促进新的安全和建筑指南。对更快的施工周期和更高的生产率的需求需要用于提升和连接要安装和装载在早期混凝土中的混凝土元件的锚定件。然而，评估锚固件的最佳实践是基于成熟的混凝土。也有越来越多的使用辅助胶凝材料与未知的影响锚。该项目旨在应对建筑业的这一挑战。该项目计划通过实验和分析研究早期蠕变对锚安装的影响，以及影响混凝土中浇筑和后安装机械锚的滑动行为和最终性能的因素。这些研究将为新的设计指南提供信息。
