Relationship between porosity characteristics and concrete frost durability in bridges

Current requirements for concrete mix design for bridges, including the acceptable absorption value of nw ≤ 4% are being widely discussed. This paper presents the results of the research conducted on concrete with granite aggregate content. The research involved the analysis of relationshp between strength, absorption, permeability, porosity structure and the freeze-thaw resistance of air entrained and non-air entrained concretes with variable W/C ratios.
