The Perry Construction Progress

Substructure Finale
FACT: Concrete and steel are partners when it comes to structural integrity. Concrete has outstanding strength in compression but it ranks weak in tension. Meanwhile, steel outperforms concrete in tension. The two materials together can resist tension and increase flexural strength. Further, the coefficient of thermal expansion is similar for concrete and steel, so when reinforced concretes freezes or gets hot, the two materials contract and expand similarly. If they didn’t, the combination would tear itself apart over it.
