AbstractNorth American mortar technology has been developed over the past fifty years and relies heavily on concrete technology. For example, compressive strength, which is a main requirement in mortar specifications, is essential to concrete, a structural material, but is only one of many properties of mortar, which has low tensile and flexural strengths and very high compressive strength. Architects and engineers have difficulties establishing a relationship between several current mortar test methods and "in situ" practice. There is a need for mortar technology that takes into account the function of mortar in a masonry wall and its interaction with masonry units. The new technology should also be sufficiently flexible to allow for an assessment of the new materials appearing on the market and to demonstrate the advantages of masonry. The paper examines certain reasons for the present situation, including difficulties in measuring mortar properties and mentions options such as the prism test and Scandinavian methods designed to match compatible mortar and masonry units.
