6. From two tests carried out with 2-point load cell on silt sand mixture (50/50) stabilized with
cement and ImmoCem it can be concluded that the tensile bending strength of 2.5 to 2.75
MPa can be expected and that the breaking strain at failure of 750 à 875 µm/m can be
achieved.
This corresponds to the stiffness modulus at failure of 2900 to 3700 MPa.
As limited as this research is, the results suggest that the ImmoCem material has potentially a wide
range of applications in construction.
The challenge of obtaining and maintaining large strain at failure is to limit the variation in the
strength while maintaining the increased average strength. Depending on the intended field
applications the either the fatigue or the tensile bending strength and/or the compressive strength
can be most relevant.
