This session will explain how silica fume lends to heightened sustainable and resilient construction. License design professionals, contractors, producers, and students will learn how silica fume lends to the overall lowered embodied carbon in structures. Topics will include extending service life through enhanced durability with silica fume, reducing member size in design when using silica fume concrete, increasing particle packing in concrete mixtures (SCC and HPC), and reducing water and cementitious material content when using silica fume in concrete pumping. In addition, case studies will exemplify the lowered embodied carbon and sustainable and resilient benefits to construction projects.

The contents of this course include 3 recorded presentations from the ACI 2023 Fall Convention:
1. Inter- and Intrasource Variability of Silica Fume and Their Effects on Reactivity; Jedadiah Burroughs, USACE Engineer Research & Development Center
2. Silica Fume - Marrying Sustainability with Resilience; Eckhart Buhler, Ferroglobe
3. Using Silica Fume to Facilitate Pumping and Enhance Productivity in High-Rise Construction; Kamal Khayat, Missouri S&T

1. Silica fume concrete increases the durability of concrete structures, lowering the overall embodied energy through increased service life.
2. Including silica fume in concrete mixtures as an SCM can replace the concrete's portland cement content and lower the mixture's embodied energy.
3. Using silica fume in concrete structures that can reduce specimen size, thus lowering the volume of concrete necessary and reducing the overall embodied energy of the structure.
4. The design of long-life structures and effective life cycle management of existing structures will enable the construction of housing and infrastructure that contributes to the protection of the environment and ensure public safety, health, security, serviceability, and life cycle cost-effectiveness.
