This paper examines the subject of creep and shrinkage in mortars. Previous research has revolved around brickwork or blockwork piers. An experimental program was devised to measure the shrinkage and creep in mortarts alone, using a range of seven mortar mixes. Some of the findings confirm earlier research, but considerable additional information concerning creep and shrinkage in mortars has been obtained. Results indicate that the quantity of line in a mortar is related to shrinkage and creep: the richer the mortar is in lime, the higher the values for creep and the lower the values for shrinkage. The laboratory data add to existing knowledge of mortars and their properties.
