通过运用图像分析软件matlab来分析混凝土的微观结构,试验结果表明:相比较同一批试块而言,标准养护条件下其骨料的等效直径要比自然养护条件下要大;matlab处理条件下可以清晰的看出混凝土的孔隙分布。与传统的方法相比,二值图像很直观、清晰,通过matlab的处理方式更为方便快捷,且能准确分析出骨料的最大、最小粒径及粒径大小。 By using the image analysis software matlab to analyze the microstructure of the concrete, the experimental results show that compared with the same batch of test blocks, the equivalent diameter of the aggregates under standard curing conditions is greater than that under the condition of natural curing; under matlab processing conditions Can clearly see the pore distribution of concrete. Compared with the traditional method, the binary image is very intuitive and clear. It is more convenient and quick to process by matlab, and can accurately analyze the maximum, minimum and size of aggregates.
