摘　　要：高强混凝土具有强度高、负荷能力大、资源和能源消耗少以及耐久性优异等特点,在国内外众多工程中得到应用。然而,高强混凝土在应用过程中依然存在黏度大、体积稳定性差以及脆性大等问题。从高强混凝土特点出发并结合现有研究成果,分析问题产生的原因以及关键影响因素,并提出相应的调控措施。High strength concrete is widely used in many domestic and oversea projects due to its advantages,such as high strength,high load bearing capacity,low energy and resource consumption and good durability,etc.However,the defects of large viscosity,bad volume stability,high brittleness still exist in the construction of high strength concrete.Considering the characteristics of high strength concrete and combining current research results,the reasons for the problems are analyzed as well as the key influence factors.The corresponding measures to control the defects are proposed.
