Similar to the crushing morphology of recycled aggregate pervious concrete, cracks are mostly like to happen where pore density is high and the paste-aggregate bond is weak [53]. When the specimen are loaded, a lot of cracks emerge at the peak stress as the existing cracks progressively are widened and produced new ones.
