Research on the Mechanical Properties and Damage Model of Cemented Sand under Uniaxial Compression

Abstract

Using cement to solidify the sand is a effective way to prevent sand from erosion in the sea bank. To investigate the mechanical properties of cemented sand with different cement content, a series of unconfined compression tests were performed. In addition, to better describe the damage constitutive relation of cemented sand, a damage model with volume change considered were deduced. The results indicate that the unconfined compressive strength and deformation modulus increases linearly with the increase of cement content. The constitutive model with volume change considered can effectively fit the curves obtained from the test and describe the damage process of cemented sand.
