在线搅拌机测量的改进被强加在采用日益复杂的制造工艺的不断增长的混凝土工业中。在这项工作中，我们讨论了一种在线图像分析技术应用于混凝土搅拌的监测，这是基于在搅拌床的表面拍摄的照片的纹理的演变。该方法是用来研究在一个密集的实验室规模的搅拌机三种不同的配方：一个难以混合的混凝土，自密实砂浆和易于混合水泥浆的加工过程中的膏体的演变。质地的演变允许获得关于混合期间不同制剂演变的重要信息;此外，该技术允许以良好的可重复性鉴定混合物演变的主要特征点，即内聚时间和流动性时间。(C)2016爱思唯尔B. V.保留所有权利。
The improvement of inline mixer measurements is imposed in a growing concrete industry employing increasingly complex manufacturing processes. In this work we discuss an inline image analysis technique applied to the monitoring of concrete mixing, which is based on the evolution of the texture of pictures taken at the surface of the mixing bed. The method is used to study the evolution of the paste during processing in an intensive laboratory scale mixer for three different formulations: a hard-to-mix concrete, a self-compacting mortar and an easy to mix cement paste. The evolution of the texture allows obtaining important information on the evolution of the different formulations during mixing; in addition, the technique allows identifying with a good repeatability the main characteristic points of the mixture evolution, i.e. the cohesion time and the fluidity time.
