Strengthening of pure lime mortars with nanoparticles of calcium hydroxide

Abstract eng:
CaLoSiL E25 is a suspension of nanoparticles of calcium hydroxide in ethanol, which has been developed as a consolidant for lime mortars. As a preliminary study, the behaviour of the product was evaluated on laboratory samples before on-site testing. Pure lime mortars were produced with different aggregate/binder ratios, in order to obtain cured mortars with different pore-size distributions and different strengths. After full carbonation, these lime mortar specimen were consolidated with several cycles of CaLoSiL E25. The changes in water transport were evaluated according to the number of cycles applied. The consolidation effect of the treatment was measured by three techniques developed in our laboratory for determination of flexural, compressive and tensile strengths on small samples.
