Smart, Durable, and Sustainable: Designing Concrete Structures for Tomorrow

使用生态高效建筑材料的好处是显而易见的，但人们对加拿大极端气候下可持续结构在现实环境和结构荷载条件下的长期性能知之甚少。与传统混凝土相比，使用再生混凝土骨料和低水泥含量可以减少结构混凝土的环境足迹，提供显著的可持续性好处，但由于对结构性能和耐久性的担忧，它们在该领域的使用一直受到限制。需要开发新的设计方法，以克服普遍存在的一种看法，即可持续混凝土天生就不如结构应用的传统配合比设计。拟议的研究计划旨在解决这些重要的知识差距，以确保加拿大在不损害其关键基础设施的长期耐久性的情况下，继续在可持续发展方面处于领先地位。

The benefits of using eco-efficient building materials are evident, yet relatively little is known regarding the long-term performance of sustainable structures subjected to combined realistic environmental and structural loading conditions in extreme Canadian climates. Structural concrete can be designed with reduced environmental footprints using recycled concrete aggregates and low cement content providing significant sustainability benefits compared to conventional concrete, but their use in the field has been limited due to concerns about structural performance and durability. New design methodologies need to be developed to overcome the prevailing perception that sustainable concrete is inherently inferior to conventional mix designs for structural applications. The proposed research program aims to address these important knowledge gaps to ensure that Canada continues to be a leader in sustainable development without compromising the long-term durability of its critical infrastructure.
