ABSTRACT

Figure 1 shows that the size of specimens is 100 mm × 160 mm × 1200 mm. The concrete protective layer thickness is 20 mm. N1 is erect steel wire which used 8 well. The reinforcement ratio (ρ) of all specimens are in the proper range, the reinforcement ratio listed (ρ) in Table 2. Table 2 is the material list of specimens, The specimens numbered SL2-1∼SL2-3 made of high titanium heavy slag aggregate, the beams numbered OL1-1∼OL1-3 are ordinary aggregate concrete.
