Compressive Mechanical Properties of a Novel Recycled Aggregate Concrete with Recycled Lightweight Aggregate

Table 2

Compressive performance of recycled lightweight aggregate concrete.

Replacement rate (%)	fcu (MPa)	fc (MPa)	fc/fcu
0	37.62	25.55	0.68
25	31.82	24.76	0.78
50	27.72	24.53	0.88
75	26.68	22.54	0.84
100	20.57	21.30	1.04

Note. The cubic compressive strength is expressed by f_cu. The axial compressive strength is expressed by f_c.
