Establishing Random Aggregate Model of Recycled Concrete by MATLAB

Random aggregate model of recycled concrete is set up based on the understanding of recycled concrete mesostructure.First of all, the number of particles of all kinds of aggregate size was obtained on the 2 d and 3 d level by fuller grading theory and navarre gradation formula, then, Using carlo method ,the specific placement algorithm is developed based on the MATLAB language to generate the two-dimensional circular, three-dimensional ball geometric model of random aggregate.Finally, combining with the characteristics of recycled concrete, the simplified model of recycled concrete is put forward by improving the geometry model of random aggregate of ordinary concrete .The establishment of a typical two-dimensional circular, three-dimensional ball geometric model is completed in the ANSYS.
