Abstract
The paper compares the behaviour of three types of integral water-repellents (WRs) on air lime mortars. These were based on sodium oleate, silane and silicone resin. Results demonstrated that sodium oleate was the most effective in reducing water absorption without compromising water vapour permeability, but decreased mechanical strength. Conversely, silicone resin had the lowest impact on porosity and water absorption, but it was the only WR that increased mechanical strength, even at early ages. These trends were intensified with increasing WR dosage. Silane had a performance between that of the other two substances. Based on the results, silicone resin has the highest potential to be used in lime mortars for restoration purposes.
