The results of the first statistical studies of the mechanical properties of the new construction material of MONICA are presented. The statistical parameters of the strength and yield strength, the relative elongation, Young’s modulus and hardness are established. The interrelations of the strength — plasticity and strength — hardness characteristics for this material are analyzed.

dispersion of properties, ultimate strength, yield stress, elongation at break, hardness, Young’s modulus, stretching curve, empirical distribution function of a random variable, parameters of the distribution function
