Results of WPG, ASE, BE, WU, and density

Treatment	WPG (%)	ASE (%)	WU (%)	BE (%)	Density (g/cm3)
Untreated	0a	0a	112.2 (±11.1)c	2.2 (±0.5)a	0.31 (±0.03)a
MEG	46.8 (±10.1)b	55.8 (±9.4)b	64.4 (±4.0)b	4.2 (±0.6)b	0.44 (±0.04)b
0.5% MEGSiO2	56.7 (±3.3)c	67.2 (±9.0)c	31.7 (±6.1)a	6.3 (±0.8)c	0.46 (±0.04)b

WPG, weight percent gain; ASE, antiswelling efficiency; WU, water uptake; BE, bulking effect.
Values followed by the same letters show no real difference based on the Duncan test.
