Abstract

Concrete is a heterogeneous material with a highly non linear behavior, which is mainly caused by the initiation and propagation of micro cracks within the several components of the material. The damage behavior of CONCRETE is usually simulated on the macro scale using complex constitutive models. The direct determination of the homogenized material parameters is often difficult and sometimes impossible. Furthermore these materials models do not explicitly represent effects and bond behaviors of interfaces between the several components. So in order to predict of CONCRETE behaviors and characteristics, it should be modeled as a three phase composite material consisting of aggregate, interfacial transition zone (ITZ) and cement paste. The size and distribution of aggregate affects CONCRETE characteristics. Because of the random distribution and size variation of aggregate in CONCRETE, the modeling of CONCRETE behavior based on component in meso structure is difficult and so we must use simple assumption. In this paper with mixing design and GRADING curve we developed a simple method to replace real aggregate with equivalent sphere aggregate with effective diameter. So we can use simple methods instead of complex numeral and randomness or x ray methods to find effective diameter and use it to determine two arrangements with maximum and minimum aggregate volume as a repeatable basical element. As a result we can use this element to modeling the behavior of sample CONCRETE in meso scale and three phases.
