Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin MK, manufactured by thermal activation-calcination of domestic kaolin clay, and commercial matakaolin CMK . Performance of the composite cements was evaluated through the setting time initial and final, compressive strengths for ages 2, 7, 28, 90 and 180 days and soundness, and compared with control cement Portland cement – CEM I. After 28 days, compressive strength was higher than that for control cement for cements prepared with addition of CMK, and with addition of up to 25 % MK.
