Abstract
This study investigates the effect of linseed oil on the microstructure of lime and lime-metakaolin pastes after 68â¯months of curing under controlled conditions. The hydrophobicity imparted by linseed oil to the pastes' bulk was confirmed by measuring water drops' contact angle. The results of thermal analysis, X-ray powder diffraction, and Fourier transform infrared spectroscopy showed that linseed oil significantly hindered the carbonation reaction in both lime and lime-metakaolin pastes and promoted the development of amorphous phases. The obtained results also indicated that linseed oil could foster the pozzolanic reaction in the lime-metakaolin system by stabilizing and/or promoting the development of hydration products resulting in reduced shrinkage in comparison with the reference.
