Abstract
The capacity of various consolidating liquids to strengthen weak mortars is reported in this paper. Commercial products (CaLoSiL IP 15, KSE 100) and liquids prepared in laboratory by dissolving chemicals in water (barium hydroxide, ammonium oxalate, ammonium phosphate) or by dilution more concentrated products (Syton X 30) were used for the experiment. In order to study the influence of the mineralogical composition of the mortar, various sorts of sand were alternatively used in the experiment for the mortar preparation. The efficiency of the treatment was evaluated as mechanical strength change measured on different shape specimens - on tubes for compression strength, on thin plates for tension test and on beams for flexural strength. All the tested consolidation agents showed positive strengthening effect when they were used for consolidation of the poor lime mortar, with the exception of the influence of lime water on the flexural strength. Very different results were achieved on soil-based mortar.
