A Study on the Flexural Experment of Precast Culvert with Slag

This study is intended to discuss the application of blast slag for concrete to improve the durability of precast concrete box culvert. The precast concrete box culverts with blast slag are tested to verify the effect of early strength. The results show that the initial cracking load and yielding load of the blast slag concrete members are increased when they are compared with those of the normal concrete. In the prototype precast concrete box culvert experiment, initial crack control effect and ductility index are increased. It can be concluded that the use of blast slag was improved the durability in precast concrete box culvert.
