From data obtained by subjecting cubes cut from dry-tamped silo staves to durability cycles consisting of frost action alone or a combination of frost and acid action, it is concluded that the transverse strength and absorption are not adequate criteria of the durability of dry-tamped silo staves. From a discussion of exposure conditions and evidence obtained from field inspection, it is concluded that frost action is the chief factor in silo durability though acid action is still important because of its accelerating effect on the rate of disintegration in freezing and thawing tests. The procedure for a durability acceptance test is proposed.
