heal.abstract	In order to evaluate the pozzolanic activity of metakaolin, several pastes were prepared, by mixing metakaolin with hydrated lime, in different ratios. The pastes were stored in standard conditions (kH=9%+/- 1%, T=25 +/- 1 degrees C) and evaluated using thermal analysis (DTA/TG), X-ray diffraction (XRD), compressive strength tests and mercury intrusion porosimetry (MIP), in time. The obtained results revealed that the compounds formed are CSH, C(2)ASH(8) and C(2)A (C) over barH(11) while C(4)AH(13) was not detected up to 270 days of curing. The calcium hydroxide consumption increases as the initial amount of the metakaolin in the paste augments. The maximum strength development is obtained for metakaolin/lime ratio:1.	en
