Study on the Stiffness and Deformation Performance of Self-Compacting Concrete Prestressed Beams with Mechanized Sand

There are more studies on self-compacting concrete but less on self-compacting prestressed concrete members using mechanism sand. In this paper, the stiffness and deformation performance of the test members are investigated by observing the mid-span deflection and concrete strains in different cross-sections during and after the tensioning process of 19.2-m mechanism sand self-compacting prestress...
