Decreasing Embodied Greenhouse Gas Emissions in One-Way Slabs Through Concrete Strength Reduction and Thickness Optimization

CSBE news

Concrete slab thickness is a key driver of embodied GHG emissions in modern buildings. This is in part driven by a widely-used method to select slab thickness which is based on the span-to-depth ratio and usually provides conservative slab thickness values. Optimizing...

Carbonation-activated microstructural refinement in GUL-GGBFS blended mortars: shrinkage mitigation and strength enhancement

CSBE news

In line with Canadian low-carbon roadmaps, the cement and concrete sector need to reduce greenhouse gas emissions to achieve net-zero targets by 2050. As clinker production is the primary source of cement-related CO2 emissions, reducing clinker content through...

Design Database Development and Comparative Performance Assessment of Connections in Cross-Laminated Timber Construction

CSBE news

The problem To grow housing without growing emissions, the AEC sector must rapidly scale lower-carbon, high-performance materials such as mass timber. Cross-Laminated Timber (CLT) has become a leading panelized option for mid- to high-rise buildings as codes in Canada...
