Machine-made sand was significantly different from natural sand in terms of particle gradation, morphology, composition and structure. The concrete composed of mechanical sand and natural sand was greatly influenced by the physical and chemical properties of sand and gravel in terms of its microscopic appearance and macroscopic properties. Therefore, this paper aimed to systematically analyze the big data of machine-made sand performance testing, and focus on the fluctuation of the fineness modulus, stone powder content, and other indicators of machine-made sand particles in various regions of Shaanxi, and solve measures were further discussed
