This paper mainly introduced the application of C40 fine-aggregate concrete in the Cast-in-place prestressed concrete hollow slab, the application effectively solved a series of construction difficulties such as small bar spacing, difficult pumping and filling. By taking measures of controlling the quality of materials, concrete production process and the construction site to realize the smooth casting of C40 fine-aggregate concrete. After the later detection, this concrete met the requirements of prestressed tensioning and the application effect proved to be ideal.
