Mechanical Properties of SiO₂-Coated Carbon Fiber-Reinforced Mortar Composites with Different Fiber Lengths and Fiber Volume Fractions

Table 4

Mix proportions of mortar.

Type of mortar	W/C (%)	C : S ratio	Fiber volume fractions (%, in vol)	Fiber lengths (mm)	Content of SP (cement × 1.0%)
CC	50	1 : 3	0.5	6, 12	1.0
