Abstract: Effects of three kinds of mineral admixtures ( fly ash, slag power and metakaolin ) on the compressive strength and volume stability of concrete are researched. Different dosages of mineral admixtures are added into concrete with strength grade C60 by the methods of separate addition and compound addition. The experimental results show that the shrinkage of concrete specimens is decreased after adding fly ash and metakaolin separately. At 60 days, contrasting to the blank sample with no admixtures, the shrinkage of concrete specimens with 20% fly ash is decreased by 19.07%, the shrinkage of concrete specimens with 10% and 20% metakaolin is decreased by 28.66% and 30.27% respectively. The compound addition of 10% metakaolin and 20%fly ash has a better effect on reducing the concrete shrinkage, according to data, this concrete shrinkage is only about 60.02% of the blank sample, at the same time, 28d compressive strength reaches to 63.5MPa, which is not much difference to the blank sample.
