Consolidation of porous limestone with nanolime laboratory study
Original language description
Effects of a lower and a higher concentrated nanolime product CaLoSiL after its multiple applications on porous limestone have been studied and presented in the paper. The assessment of the consolidating efficiency of the products was based on performance of both the destructive and the non-destructive laboratory tests: bending and compressive strengths, ultrasound velocity measurements and porosity determination of stone specimens. Concluding the test results performed for the depth profiles of specimens, two applications of the CaLoSiL E 25 or IP 25 products seem to be an optimal procedure for treatment of the studied porous limestone. Further applications of the product especially in the case of the higher concentrated CaLoSiL E 50 resulted in an uneven distribution of the measured characteristics (strength and porosity) due to an accumulation of the consolidating product near the surface. The appropriate amount of the product (both the concentration of the effective compound and the sum of the product applications) should be chosen in relation to the stone porosity and the treatment condition in order to achieve a regular distribution of the product in the substrate.
