Abstract: | This paper deals with the efficacy of creating artificial carbonate sand from crushed chalk to model the natural carbonate
sand. Direct drained shear using 100 mm shear box and compressibility tests using 150 mm Rowe cell have been performed on
artificial carbonate sand in order to determine the shear stress-strain and compressibility characteristics of the artificial
material. These are compared with data from natural carbonate sands given in the literature. The results obtained demonstrate
that shear stress-strain and compressibility characteristics of the artificial material closely mirror that of natural carbonate
soils. The artificial carbonate sand shows generally similar characteristics, which are in the range of the natural carbonate
material. |
