Porous concrete is a material designed to manage stormwater in urban areas while reducing environmental impact. Unlike traditional concrete, which uses fine aggregates like sand, porous concrete incorporates larger aggregates, creating voids that allow water to percolate through. This permeability helps reduce surface runoff, mitigate flooding, and recharge groundwater. This resource, created by science communicator Mike Stone, covers the material’s composition, including the critical water-to-cement ratio for optimal strength and workability. It also highlights the role of porous concrete in sustainable urban planning, particularly in regions experiencing increased rainfall due to climate change.
