Resonant Column Testing of Microfine Cement Grouted Sands
Torsional resonant column tests were conducted on microfine and ordinary cement grouted sands and shear modulus and damping ratio values were obtained. The effect of confining pressure, shear strain, cement type and gradation, grout water-to-cement (W/C) ratio and sand gradation were investigated. The shear modulus of the grouted sands increased with increasing confining pressure, decreasing shear strain and decreasing W/C ratio, while the damping ratio increased with decreasing confining pressure, increasing shear strain and increasing W/C ratio. The effect of other material parameters was minor or negligible.
