Cylinder specimens (U100200 mm) were made by
rodding 25 times in three layers, and then applying a vibration
for 10 s. The concrete panels for the water-purifying tests
(400400100 mm) were made by rodding in two layers,
and then applying a vibration for 10 s. The test specimens
were removed from their forms after 48 h and cured under
