Compression Behavior of Confined Columns with High-Volume Fly Ash Concrete

Table 2

Mix designs for OPC and HVFAC.

Binder type	W/B (%)	S/a (%)	Unit weight (kg/m^3)					Superplasticizer (% by cement weight)
			W	C	FA	S	G
OPC	50.0	40.2	175	350	0	710	1,054	0.05
HVFAC	35.0	44.1	120	154	189	821	1,042	1.50

Note. S/a is the sand-to-aggregate ratio; W is water; C is cement; FA is fly ash; S is sand; G is gravel.
