Cracking is almost completely avoided in prestressed concrete . 预应力混凝土几乎可以完全避免出现裂缝。
The successful alternative was the cast-in-place segmental prestressed concrete box girder . 最后采用的方案是分段现浇的预应力混凝土箱形梁。
They would certainly be less pleasing to the eye and often more expensive than the prestressed concrete beam . 与预应力混凝土梁比较，它们自然更显得外貌粗拙，不甚美观，而且成本也往往更高一些。
