    Abstract

    The introduction into North America of a chemical specifically designed to retard setting of cement and lime mortars has led the way to the introduction of ready-mixed mortars for the masonry industry. Such mortar is delivered to the job site ready for use in containers; it can be kept up to 48 h and used at any time during this period. Once the mortar is placed between masonry units, it sets like an ordinary mortar. In this paper, the properties of Type S ready-mixed mortar are experimentally evaluated. The effect of elapsed time from production to use on compressive strength and tensile and shear bond are studied. Tensile and shear bond are established by using a centrifugal force testing apparatus developed by the authors.
