Influence of Curing Time on the Drying Shrinkage of Concretes with Different Binders and Water-to-Binder Ratios

Table 1

Chemical compositions of cement, GGBS, and fly ash (%).

	CaO	SiO2	Al2O3	Fe2O3	MgO	Na2	Loss on ignition
Cement	63.59	21.86	4.25	2.66	2.19	0.55	1.75
GGBS	36.44	31.76	14.84	0.60	9.08	0.56	0
Fly ash	2.44	48.67	30.95	5.62	1.15	0.78	7.65

Note. Na₂ = Na₂O + 0.658K₂O.
