Effects of Coarse and Fine Crushed Clay Brick Content on the Compressive Strength of Recycled Aggregate Concrete and the Microscopic Mechanism

Table 5

Compressive strength test scheme.

Experiments	Concrete type	Water-cement ratio	Coarse crushed clay brick content/(%)	Fine crushed clay brick content/(%)	Age/(d)
Compressive strength	RAC	0.4	0, 15, 30, 45, 60	0, 15, 30, 45, 60	3, 7, 14, 28, 60
	NAC		0, 15, 30, 45, 60	0, 15, 30, 45, 60
