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

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