Concrete Mixes for Durability: A Hybrid Mathematical Optimisation Approach

该项目将引领混凝土配合比设计方法论的范式转变，该方法目前专注于满足混凝土的机械性能目标，以一种整体的方法来最大限度地提高混凝土的耐久性和机械性能。该方法基于混合方法，包括基于经验制定的耐久性和机械性能目标函数的混凝土配合比的数学优化。所提出的优化模型的多目标特性将允许同时考虑几个设计目标，包括：最小化开裂的总体风险，最小化渗透性；并最大限度地提高力量发展速度。

This project will lead a paradigm shift in concrete mix design methodology, which is currently focused on meeting the mechanical performance objectives of concrete, to a holistic approach that maximises durability of concrete alongside its mechanical performance. The approach is based on a hybrid methodology involving mathematical optimisation of concrete mix based on empirically formulated objective functions for durability properties and mechanical properties. The multi-objective nature of proposed optimisation model will allow simultaneous consideration of several design objectives including: minimising the overall risk of cracking, minimising the permeability; and maximising the rate of strength development.
