摘　　要：用正交设计法配制高强混凝土,对影响混凝土抗压强度、劈拉强度和抗折强度的水胶比、减水剂掺量、矿渣微粉掺量和硅粉掺量等主要因素进行分析,确定高强混凝土合理的配合比,并回归分析了高强混凝土劈拉强度与抗折强度的关系。结果表明,水胶比和硅粉掺量对高强混凝土强度影响最为明显。This paper studies high-strength concrete by using orthogonal desigh method.The main factors of water-binder ratio,water reducer content,slag powder content and ganister sand content are analyzed,which affect the compressive strength,splitting tensile strength and bending strength.Then,rational high-strength concrete mix proportion is determined.And the relation between bending strength and splitting tensile strength of high-strength concrete is analyzed.It indicates that water-binder ratio and ganister sand content have significant effects on the strength of high-strength concrete.
