The invention relates to a concrete mixture workability determination method and device, and the method comprises the steps: carrying out the feature extraction of a monitoring video sequence of current concrete based on a visual algorithm, and obtaining a homogeneity feature value and a slump feature value of the current concrete; based on a deep learning method, performing feature extraction on the monitoring video sequence to obtain image features of the current concrete; and substituting a feature set composed of the homogeneity feature value, the slump feature value and the image feature of the current concrete into a pre-constructed classifier to obtain the homogeneity category and the slump grade of the current concrete. According to the invention, intelligent monitoring of the concrete workability is realized, the defects of time and labor waste, low efficiency and poor real-time performance of manual monitoring in the past are overcome, and the requirements of low cost and high performance of enginee
