Strength-Related Data of Grouts
This Chapter deals with grout-mix design issues related to the targeted strength of the masonry to be grouted. Only two parameters enter the discussion: targeted fwc-value and corresponding required fgr,c-value. The chapter explores how a range of required fgr,c-values suffices to be related to a targeted fwc-value. This loose correlation is due to the fact that grout-to- stone bond properties are shaping the final structural behaviour of grouted masonry. Thus, tensile rather than compressive strength of the grout is the relevant parameter. Besides, dehydration of grout entering the masonry takes place; consequently, some additional rules regarding mix-composition are respectively derived. Finally, several empirical relationships are offered predicting masonry compressive strength before and after grouting. Obviously, among the grout compositions resulting in fgr,c-values within the required strength range, those mixes will be retained respecting the other required performances. The Chapter ends with a long Appendix presenting detailed strength results (both tensile and compressive) for several grout compositions, described in literature.
