Hello,
When adding portland cement to a silty or sandy material, what is the effect on the shear strength. Obviously, the cohesion will increase, similar to a naturally cemented deposit but what happens to phi ?
Does addding portland cement to soil only increse the cohesion and the frictional component remains essentially unchanged ?
OR ?
It would seem that as the cement content increases, the material would begin to behave more like traditional concrete (stress independant) rather than a frictional material. Therefore, the strength of the soil would be determined using a test similar to how concrete is tested, unconfined compressive strength.
Your comments and/or references to technical publications would be appreciated.
