Abstract
Grout is an essential element in reinforced and prestressed masonry constructions. A review indicates that in the earlier studies on grouted masonry many of the parameters (block geometry, core taper, face shell/full mortar bedding, two/three course prisms and stack/running prisms) are not standardized. This has resulted in contradictions. Also, the influence of relative strengths of grout, mortar and block has yet to be elucidated. In order to generalize the effect of block-mortar and block-grout strength ratios, a three-dimensional finite element analysis of grouted masonry with a standardized structurally efficient block geometry has been carried out. To clarify the influence of block-mortar and block-grout strength ratios, the behaviour of grouted masonry is compared with that of solid masonry and also monolithic prisms rather than with ungrouted hollow block masonry, and this is discussed through a detailed analysis of stress distribution along different vertical sections of block, grout and mortar. © 1995, Thomas Telford Ltd.
