Detailed Webinar Instructions
Description
This webinar is jointly sponsored by NEx: An ACI Center of Excellence for Nonmetallic Building Materials and the American Concrete Institute (ACI).
Insulation of foundations of residential homes is critical to reduce the heat loss, lower the heating cost, and build energy-efficient homes. In this webinar, the thermal and structural performance of a modified concrete slab with partial replacement of coarse aggregates using expanded polystyrene (EPS) as a slab-on-grade foundation for residential homes is presented. The design of such slabs with incorporation of EPS and their effects on concrete design and strength will first be discussed. Thermal performance of the foundations using EPS-modified concrete slab from thermal insulation tests on slab-on-grade foundation systems will then be presented. In addition, the structural integrity of EPS-modified concrete foundation using large-scale plate load test under different load levels will be discussed. The webinar will then conclude with a brief discussion on the future research needs and development of guidelines on using EPS-modified concrete in slab-on-grade foundation applications.
