【Abstract】 The optimizing design method of non-vibrated concrete has been put forward. Non-vibrated expansive high strength concrete has been prepared. The properties of this kind of concrete are good enough for modern concrete projects: the 28 d compressive strength of non-vibrated concrete is over 60 MPa, and the slump is over 24 cm, and the flow value is over 60 cm without bleeding and segregation.更多还原
