用统计连续理论研究混凝土的力学性能

混凝土材料可看成由骨料，水泥水化物和砂浆组成的三相非均质材料，或看成由骨料和细砂组成的二相非均质材料，本文提出了等效常数的概念，把混凝土看成随机非均匀连续介质，用统计连续理论研究其力学性能，并给出了计算等效弹性模量的公式。

Study of Mechanical Properties of Concrete on the Statictical Continuum Theory

Concrete products can be considered as three phase anisotropic materials made of aggregate, cement hydration and grout or two phase anisotropic of aggregate and refined grout. The concept of equivalent modulus is proposed in this paper. Concrete may be thought of random anisotropic continua and its mechanical properties are investigated based on the statistical continuum theory. The formulae for calculating equivalent modulus are also proposed.
