Abstract
Repairing historical masonry structures by grout injection is very important since
it involves preserving the historical character of the structure while restoring and
repairing it to ensure its structural integrity. Different pilot tests in hydraulic
conditions have been conducted and several mixes with Portland cement and
microfine cement (both with admixtures) were used. The quality control of
grouting is a necessity to make sure that the objectives of consolidation by
injection are achieved without damaging the structure by excessive grout
pressure. Water tests before and after grouting are an effec
