COMPARISON OF EXPERIMENTAL AND SPACE SIMULATION APPROACHES TO PARTICLE PACKING IN CONCRETE

摘要

Experimental investigations of cementitious materials are the wide-used methods forconcrete research field. But sometimes, they are time-consuming and condition limited.Production of computer-simulated concrete can reduce time and efforts bestowed onassessment of geometrical properties of material structure. Realistic representation of particledispersion is particularly relevant when the researcher is interested in aspects of materialperformance that rely on such material configuration characteristic. Conventional sequentialrandom (particle) addition (SRA) computer simulation systems are unsuitable in practicalterms to produce higher particle densities, and fundamentally incapable of producingcomputer-made-concrete (compucrete) with properly dispersed particles. In this paper,concurrent algorithm-based SPACE system's estimates for properties of concrete structurewith different configuration sensitivities are compared with experimental data and shown tobe quite similar. This proves SPACE-produced compucrete is suitable for investigations ofeven configuration-sensitive features of material structure.
