- •
Elastic properties of MKG pastes with different AE dosages and Ms levels were measured.
- •
Fracture behaviors of MKG pastes were characterized by axial and lateral stress-stain curves.
- •
AE dosage has a dual effect on Young's and shear moduli characterized by a quadratic double-logarithmic function.
- •
Increasing AE dosage tends to promote Poison ratio and bulk modulus characterized by a sigmoid function.
- •
Ms level has no obvious influences on the elastic properties of MKG pastes.
