Fig. 4 24-houre water absorption 4.3. WEIGHT OF MASS The specific density of concrete depends on the specific weight of the sand and the porosity of the roller concrete mass. There are a few air vents in roller concrete, varying between 0.5 and 5%, which reduces the action of compacting. The results showed in figure 5.
