WebTECHBRIEF Freeze-Thaw Resistance of Concrete with Marginal Air Content FHWA-HRT-06-118 Abstract Freeze-thaw resistance is a key durability factor for concrete pavements. Recommendations for the air void system parameters are normally 6 ± 1 percent total air and a spacing factor of < 0.20 millimeter (mm) (0.008 inch). However, it was observed that WebCONCRETE MASONRY CAVITY WALL. In masonry cavity walls, insulation is typically placed between the two wythes of masonry, as shown in Figure 1. This provides a continuous layer of insulation, which minimizes the …
