摘要：

Ultrafine sand mainly refers to the fine sand excavated underground in the Yellow River Basin and Jiaozuo or Kaifeng. The fineness modulus is between 0.3-1.0, and the quality is uneven. This paper systematically studies the basic characteristics of ultrafine sand from different origins, such as the mud content, fineness modulus, and MB value, and compares its effects on the performance of the second-generation and third-generation water-reducing agents through experiments. By replacing the machine-made sand in different proportions, the work performance and compressive strength of concrete are studied.
