Material characterization and hydraulic conductivity modeling of macroporous recycled-aggregate pervious concrete

The objective of this work was to characterize the mechanical, physical, and hydraulic conductivity properties of macroporous (>30% voids) pervious concrete (MPC) containing recycled aggregates and two binder additives, namely sand and titanium dioxide (TiO2). While MPC exhibited lower compressive strength and higher permeability than normal pervious concrete, the experimental data suggest that the high absorption and low specific gravity of...
