Study of the Dynamic Mechanical Properties of Recycled Concrete Containing Ferronickel Slag Subjected to Impact

Table 3

Mixing proportions of ordinary and recycled concrete.

Specimen	RR (%)	Mixing ratio (kg/m^3)
		Water	Cement	Sand	Natural coarse aggregate	RCA	Ferronickel slag	Silica fume	Superplasticizer
N0-60	0	175	382	604	1074	0	109	55	6.55
R30-60	30	181	382	604	752	322	109	55	6.55
R70-60	70	189	382	604	322	752	109	55	6.55
R100-60	100	195	382	604	0	1075	109	55	6.55

N and R represent the ordinary concrete and the recycled concrete, respectively; RR is the replacement rate of RCA; 60 represents the concrete strength of 60 MPa.
