Table 3

Test results of the fine aggregate technical indicators.

Test index	Test method	Technical requirements	Test results
			Limestone	Diabase
Sand equivalent (%)	T0334	≥65	68.0	72.0
Fine aggregate angularity value (s)	T0345	≥30	35.3	43.1

Note. Fine aggregate angularity value can reflect the shape and surface roughness of fine aggregate.
