Properties of Artificially Cemented Carbonate Sand
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 124, Issue 6
Abstract
Naturally cemented materials often have inherent variabilities in density and degree of cementation. The influence of this variability on the properties of cemented materials is investigated by producing artificially cemented specimens at dry unit weights ranging from 12 to 19 kN/m3 and gypsum cement contents ranging from 0% to 20%. Tests have been performed to investigate the index strengths, the behavior in isotropic and K0 compression, and the responses from standard triaxial compression tests over a wide range of confining pressures. The index properties, and the compression and stiffness parameters of the cemented sands are presented, with particular attention given to the influences of density and degree of cementation. For the artificial soil, the effects of the bonding are only significant for stresses below an apparent preconsolidation stress. The strength and stiffness increase with increasing density and cement content, but the influence of the cementation decreases as the density increases.
