This study presents the use of IBA for the production of eco-pervious concrete, aiming at enhancing the recycling rate of IBA in construction materials. The IBA aggregates are used to replace the natural aggregates (NA) in various percentages (0%, 25%, 50%,75% and 100% by volume). The effect of IBA replacement ratios and casting methods on the mechanical properties, water permeability, porosity, density and thermal conductivity of the pervious concrete were determined. The volume stability of the pervious concrete incorporating IBA was evaluated. The results indicated that the appropriate content of IBA could benefit the mechanical properties due to the internal curing effect of IBA. However, the excessive content of IBA in the pervious concrete led to reduced water permeability, connected porosity and mechanical properties. Even so, the pervious concrete containing 100% IBA could achieve the required permeability and compressive strength for permeable pedestrian pavers (JIS A 5371). In addition, the incorporated IBA in pervious concrete causes little volume expansion from the reaction between alkalis and components consisting of metallic aluminum and glass in IBA owing to its high connected porosity. Furthermore, the pervious concrete incorporated IBA had a low density and thermal conductivity, showing the potential to be applied in thermal insulation areas.
