Two kinds of binders, microbially induced carbonate precipitation (MICP) and ordinary portland cement (OPC), were used separately to produce macroporous pervious concrete (MPC). Furthermore, the macro- and micromechanical properties of these two binders and MPCs produced with them were compared. The results revealed a significant difference between the effective porosities of samples produced with MICP and OPC. In addition, the MPCs made with MICP had a higher elastic modulus in comparison to those made with OPC. Moreover, MPCs produced with MICP required less cement to achieve the same compressive strength as those produced with OPC. Finally, investigation of the boundary of MICP binder and aggregates revealed that there was no interfacial transition zone between the aggregate and the MICP binder as existed between OPC and aggregates.
