In this paper, the parameters describing the material property of wall clay blended with fibers for plastering are modeled by cohesion and angle of shear resistance based on soil mechanics. The unconfined compression experiments are carried out in order to obtain the cohesion and angle of shear resistance from Mohr - Coulomb's failure criteria, young's modulus and consumption energy from the stress-strain relationship. According to above experiments, the values of cohesion, angle of shear resistance and consumption energy indicate the constant between 0.2 kg to 0.4kg per 100L of fiber ratio for plastering against wall clay. The later, those parameters decrease lineally with the increasing of fiber ratio. However, the young's modulus increase with the fiber ratio by being affected the bond between fiber and wall clay. Then, the optimal fiber ratio against wall clay is obtained as 0.4kg/100L from above experiments.
