Concrete is also an inert material.
Material optimization measures primarily include a reasonable selection of cement, such as choosing low-heat cement.

Biaxial tensile test The biaxial tensile test is performed at the Materials Mechanics Laboratory of POSTECH on a Kokusai KBAT-100 in-plane biaxial tensile testing machine.
Equal forces are maintained throughout the test but in (strongly) planar anisotropic materials εx and εy will differ with deformation and the stress state will theoretically deviate from pure equibiaxial stress.
