Abstract:
Reports studies of the homogeneit o f air-entraining concrete by means of testing for resistnance to abrasion. An air-entraining agent was used with no added accelerators, dispersing agents or gas forming materiaIs. Since air entrainment has a tendency to eliminate bleeding of concrete it is only reasonable to believe that such concretes are more homogeneous the top surface (of a slab) would have the same strength and density characteristics as the bottom surface. Plotted data show that there is pro-gressive increase in abrasion loss in specimens as air content increases beyond 6 percent.
