Table 6 provides the compressive and flexural strengths of all the pervious concrete mixes studied. As seen in the table, SPC and PPC mixes produced in this research all have good strengths (higher than 32 MPa), even for the mixes having porosity close to 25%. More detailed analyses of the strength results are presented below.

Pervious concrete is increasingly used in the pavements and overlays subjected to heavy traffic and in cold weather regions. In the present study, strength, fracture toughness and fatigue life of two types of pervious concrete, supplementary cementitious material (SCM)-modified pervious concrete (SPC) and polymer-modified pervious concrete (PPC), are investigated. The results indicate that high strength pervious concrete (32-46 MPa at 28 days depending upon the porosity) can be achieved through both SCM-modification, using silica fume (SF) and ...
