Abstract
Many important properties of masonry, particularly strength and weather resistance, are affected to a considerable degree by the type of mortar used. One type, generally known as cement-lime mortar, is used extensively in North America and Europe for all types of unit masonry construction. This paper will review the development of this type of mortar and discuss the influence of certain of its properties on the strength, durability, and weather resistance of unit masonry. Masonry mortar is prepared by mixing sand, water, and a cementitious material. In cement- lime mortars the cementitious material is a mixture of lime and portland cement. The proportion of lime to portland cement may vary over a wide range in cement-lime mortars but generally it is not less than 20% of the volume of the cementitious material in the mortar. The proportion of cementitious material to sand also may vary in cement-lime mortars but generally it lies between 1:2 1/4 and 1:3 by volume of cementitious material to sand.
