3.2. Mechanical property tests of LWPCs
Compressive strengths were tested at the ages of 7 and 28 days
in according with ASTM C39 [25]. Before the testing, the samples
were capped at both ends with sulfur capping compound to level
the loading surface. The splitting tensile strength was tested at
28 days in according with ASTM C496 [26]. The reported results
were the averages of 3 samples.
Surface abrasion resistance was tested at 28 days by the rotating-
cutting method in accordance with ASTM C944 [27]. The samples
were left to dry for 1 day before the test (air-dry condition).
The sample was abraded with 98 N loads on the surface for 30 s
after contact between the cutter and the surface. The abrasion
resistances of each pervious concrete were done six times, three
on each side of the concrete samples.
