  ABSTRACT: This study evaluates the possibility of using metakaolin produced from kaolinite clays from the villages of adjouzoumè and Adakplamè to substitute part of the Portland cement. The two clays are ground in a corn mill and passed through an 80-micron sieve before being calcined in a kiln at a speed of 10˚C/min up to 700˚C. Once 700˚C has been reached, this temperature is maintained for one hour. Reactivity is analyzed in accordance with ASTM C618. Mechanical tests were carried out on 40 × 40 × 160 mm3 specimens to determine compressive strength. Chemical analysis was used to estimate the levels of the main oxides. The results showed that Adjozoumè and Adakplamè metakaolins have a strength activity index of 97.5% and 96.26% respectively. The main oxide contents were 94.5% and 95% respectively. In the sense of this standard, these metakaolins are reactive.
