This paper presents the study on changes of the mechanical properties, including compressive strength, split tensile strength and rupture strength of four high strength concretes, caused by the addition of ground blast-furnace slag and silica fume. Blending ground blast-furnace slag and silica fume in combination with superplasticizer in concrete (total amount is 25 % of binders' weight) shall evidently improve the compressive strength, split tensile strength and rupture strength and enhance the rupture-resistance of concrete. The appropriate dosage of slag and silica fume are both 10 % to 15 % of the total weight of bonding materials in concrete. The development of compressive strength, split tensile strength and rupture strength of concrete does not synchronize, the compressive strength develops faster than the latter two ones. The addition of ground slag and silica fume may relatively accelerate the growth of split tensile strength and rupture strength compared with compressive strength, but the fundamental relationship between the development of three strengths is unchanged. The high strength concretes in this paper obtained higher TCSR (tensile to compressive strength ratio) and RCSR (rupture strength to compressive strength ratio) values, which varied in the range of 0.070 to 0.098 and 0.126 to 0.198, respectively.
