Brucite Fiber Concrete Fatigue Performance Of The Pilot Study

Fibrous concrete is a cement composite material which is researched greatly and used widely. Its prospect is good, and now it has been used in the region of military, watercourse, architecture, road and so on. But now research of concrete reinforced by nature mineral fibrous is still absent in the foreign and is started recently in the nation. Because fibrous brucite is really cheap and the resource is rich in Shannxi, the research prospect of brucite's concrete is widely.Through a large amount of flexure fatigue tests, this paper received the fatigue life of brucite concrete under different stress levels. After statistical analysis of the dispersed test data with the Weibull distribution theory, the writer have drawn out the single logarithm and double logarithm fatigue equation of different reliability estimator and draw the P-N fatigue curve. And the paper give out the single logarithm and double logarithm fatigue equation of brucite concrete after thinking about some safe reserve .Meanwhile, the brucite concrete's enhancement mechanism, destruction mechanism and tired injury mechanism are analyzed in the base of concrete construction and theory analysis of fibrous concrete.
