Research on the Road Concrete Mixing Uniformity Control Technology

摘要

In this paper, chaos theory principle is applied in studying the concrete mixing process. Using piecewise linear mapping model describes the stirred mixture mixing and separation process. A chaotic model is established for particle movement in mixing process. In order to determine the reasonable stir parameters, the solving mixed movement method and the number of periodic windows is also given out. Suggested using chaos model determine the reasonably mixing time, proposed pre-mixed aggregate method, aggregate pre-wet method and admixture batch feeding ways to improve productivity and mixing uniformity.
