Open Access Cementing Material on Mechanical Property of Calcareous Sand

Abstract: It is difficult to obtain high quality samples of natural material covering a range of densities and degree of ce-mentation, so study on the sample preparation techniques with similar mechanical properties of natural samples are very important. Experiments were carried out to study the effects of cementation of different materials on the mechanical prop-erties of calcareous sand, e.g., the effects of contents and types of cementation materials on the strength and the character-istics of stress-strain. It is shown that Portland cement is a good cementation agent, compared to calcite and gypsum. The strength of calcareous sand increases with the increase of Portland cement content
