The main objective of these tests is to evaluate the influence of varying air content in such mixtures on the structure and frost resistance of concrete. The authors suggest that the approach presented here allows for a safe design of concrete mixtures in terms of their frost resistance. The results indicate that concrete can be resistant to surface scaling even at the W/C ratio markedly higher than 0.45. Increased addition of ggbs leads to a decrease in concrete resistance to surface scaling. Proper air entrainment is the fundamental factor for frost-resistant concrete, and the air void system has to be assessed (micropore content A₃₀₀, spacing factor L). The addition of ggbs increases pore diameters, thus, to obtain the appropriate air pore spacing factor, micropore quantities introduced have to be increased.}, type={Artykuły / Articles}, title={Odporność na powierzchniowe łuszczenie i charakterystyka porów powietrznych betonów zawierających żużel}, title={Scaling resistance and air void characteristics in concrete containing ggbs}, URL={http://www.czasopisma.pan.pl/Content/103299/PDF-MASTER/22%20Scaling%20Resistance%20and%20Air%20Void%20Characteristics%20in%20Concrete%20Containing%20GGBS.pdf}, keywords={powierzchniowe łuszczenie, napowietrzanie, żużel, struktura porów powietrznych, scaling resistance, air entrainment, ggbs, air pore system}, }
