Abstract
Mortar for masonry is important because it provides the linkage between masonry units so enabling the composite to behave as a single material. The type of mortar used determines the flexuraland compressive strength of them as onrysointhis paper, arange of mortarsis examined. These include traditional designation (iii) (1 cement: 1 lime: 6 sand), designation (iv) (1 cement: 1 lime: 9 sand) mortars as defined in BS 5628; Part 1, and two thin layer mortars denoted A and B. The conventional mortars were formed using either 42.5 N Portland cement (PC) to BS EN 197; Part 1- CEM I or 32.5 N PC to BS EN 197; Part 1- CEM I in order to ascertain the difference these two cements have on the properties of mortar. © 2005 Taylor & Francis Group.
