In this paper,it is emphasized that the raw materials for high strength concrete should be elaborately selected in order for its successful design and strength stability. Selection of materials include characteristics of cement, particle size,intrinsic strength, shape and texture of aggregate, chemical admixtures and mineral admixtures, etc. Furthermore, quality stability of cementitious materials and conformability between superplasticizers and cementitious materials are also important for material selection.
