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.

该项目将领导混凝土混合设计方法的范式转变，该方法目前侧重于实现混凝土的机械性能目标，以一种整体方法，该方法将混凝土的耐用性与机械性能一起最大化。该方法基于一种混合方法，该方法涉及基于经验表述的耐用性能和机械性能的混凝土混合物的数学优化。拟议优化模型的多目标性质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，最大程度地降低渗透性；并最大化力量发展速度。
