Abstract
A comprehensive study was carried out on the influence of Hydroxypropylmethylcellulose (Methocel F50-HPMC) on the mechanical properties of a reference sand. It was found that the nonlinear dependence of viscosity on HPMC content is in agreement with literature data. As far as the mechanical properties are concerned, no additional cohesion is generated. There is also no significant effect on the friction angle determined in the shear box and triaxial tests. The effective permeability of sand specimens can be significantly affected by changing the viscosity and thus reduced accordingly. The mechanical influence on the overall stress-strain relationship (strength as well as stiffness parameters) in the triaxial device is marginal when the pore fluid is replaced with an HPMC solution.
