Magnetic susceptibility study on metakaolin admixtured cement paste

D.Govindarajan, R.Gopalakrishnan

The present works gossip the upshot of metakaolin on the properties of Portland cement through magnetic susceptibility study. Cement pastes containing 0%, 10%, 20%and 30%metakaolin in substitution for cement and in aWater/Cement (W/C) ratio of 0.4 have been prepared. The magnetic susceptibility at different hydration ages has been determined by Faraday Curie balance method and this has been related to changes in setting time and compressive strength measurement. The results illustrate to facilitate the magnetic susceptibility increases with increasing metakaolin content in the cement.
