The volume shrinkage of different cementitious materials was investigated. The results indicates the type and fineness of cement have significant effect on the volume stability of concrete, namely, the concrete with higher fineness cement has worse volume stability, and the low-heat Portland cement has better volume stability than the mid heat Portland cement. But the mixing of mineral admixtures makes the volume stability of cementitious materials become complex. The mineral admixtures of high quality can reduce the shrinkage of hardened cement paste, and the duality system of cement-fly ash is more suitable to produce concrete of good volume stability than ternary system of cement fly ash slag powder.
