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
