4f). Mortar is a mixture of cement paste and fine aggregate; in fresh concrete, the material occupying the interstices among particles of coarse aggregate; in masonry construction, joint mortar may contain masonry cement, or may contain hydraulic cement with lime (and possibly other admixtures) to afford greater plasticity and workability than are attainable with standard portland cement mortar. The dust will prevent a good bond between the old masonry surfaces and the fresh mixture. So, what good is this stuff? The purpose of anchoring cement is to be a quick-drying cement for the fast setting of railings, machinery, bolts, and other such things into concrete, stone, brick, and masonry in general. A. This is because lime is used to add plasticity to modern cement mortars and thus, when you omit the cement you have the greatest workability. . Required fields are marked *.
