From high-pressure x-ray diffraction, the bulk modulus of monocarboaluminate was measured as 53 GPa, which is larger than any other reported bulk moduli of hydrated phases in concrete system. In addition, first-principles calculation confirmed the experiment and predicted additional elastic properties of fully and partially hydrated monocarboaluminates. The atomistic simulation implies that the additions of carbonate group and water molecules significantly attenuate anisotropic nature of calcium aluminate framework. Thus it considerably makes the crystal structure incompressible and thermodynamically stable.
