Cementing of sediment occurs naturally in many soils and weak rocks, during both early and late stages of diagenesis. Cementation can produce both an increase in both stiffness and strength, and in the case of early cementation the sediment may develop sufficient strength to preserve an open structure and high porosity even under significant burial depths.
This paper reports the results of a series of resonant column tests carried out on a range of sand-sized geomaterials to explore the effects of different cement morphologies on the very small strain stiffness of the materials. It is shown that the proportion of void space filled by cement, cement location, sand size and grain shape all have a significant effect on shear modulus. The change in stiffness between different host materials is affected by the density, specific surface and grading of the geomaterial.
