Abstract

The Cement Concrete is widely used in Highway Pavements,and its slump losses is still a thorny question to the related construction companys.Writer mainly focused on the Air-entrained Cement Concrete Pavement,has analyzed the mechanism of the slump loss and detailed illustrated the effect of the water-cement ratio,water reducing agent,air-entraining agent and the state of motion of the concrete to the slump loss by the massive laboratory test data.In addition,put forward myself views on how to control the concrete slump loss.
