- Abstract
The effect of cement-grouting plays an important role in the engineering property of cement-treated sands. To investigate the effect of different water-cement (w/c) ratios on sand cementation, one dimensional seepage test was conducted with different particle size in this study. The permeability coefficient and uniaxial compressive (UC) strength of treated samples were studied respectively. Test results indicated that with the increase of w/c ratio, the increase of permeability coefficient of sands with particle size 1.25-2.50 mm is larger than that of sands with particle size 2.50- 5.00 mm after 7 days curing time. The UC strength of treated samples decreases with the increase of w/c ratio. The larger the particle size, the smaller the reduction of UC strength. These phenomena are closely related to the formed bond strength between sand particles.
