Study on Mechanical Behavior of Reinforced Concrete Beams under Sulfate Attack

Table 1

Test results of cracking load and yield load of test beam.

Number of test beam	Cracking load (kN)	Cracking moment Mcr (kN·m)	Mcr/Mcr0	Yield load (kN)	Yield moment My (kN·m)	My/My0
No. 0 test beam	24	8	1	149	49.67	1
No. 1 test beam	32	10.67	1.33	154	51.33	1.03

Note: M_cr is the cracking moment of the test beam corroded by sulfate; M_cr0 is the cracking moment of the test beam not corroded by sulfate; M_y is the yield moment of the test beam corroded by sulfate; and M_y0 is the yield moment of the test beam not corroded by sulfate.
