Test data on the influence of age at loading on the long term movements of clay brick and concrete block masonry walls under conditions which prevent moisture loss to the ambient medium are presented. Two types of clay brick and one type of concrete block were built with a 1: 0.5: 4.5 OPC:lime:sand mortar. It was found that creep of the masonry decreased with increase in the age at loading, which agrees with previous findings for creep of masonry subjected to conditions of drying. Typically, creep of sealed walls at 160d was between 25% and 65% of that in walls exposed to drying at r.h. of 65 ±5%.
