Description of Concrete Creep under Time-Varying Stress Using Parallel Creep Curve

Table 1

Mixture proportions for the two test types of concrete.

Test type	Max. size of aggr. (mm)	W/C ratio (%)	Slump (mm)	Unit weight, (N/m^3)
				Water	Cement	Fine aggr.	Coarse aggr.
Type A	20	54	110	1,880	3,480	7,360	10,200
Type B	20	57	200	2,120	3,720	9,450	7,610
