Estimating the Tensile Strength of Ultrahigh-Performance Fiber-Reinforced Concrete Beams

Table 1

Mixing proportions of the UHPFRC.

Mixture		W	Binders			S	F	Steel fiber
			OPC	Zr	BFS			Fiber volume content, Vf (%)	Diameter, Df (mm)
FRC120	0.22	209	770	58	135	847	231	1.0 = 1.0 (19.5 mm)	0.2
FRC150	0.18	180	788	99	99	867	236	1.5 = 1.0 (19.5 mm) + 1.0 (16.5 mm)	0.2
FRC180	0.18	178	783	196	—	862	235	1.5 = 1.0 (19.5 mm) + 1.0 (16.5 mm)	0.2

OPC: ordinary Portland cement; Zr: zirconium; BFS: blast-furnace slag; S: sand; F: filler; W: water.
