Abstract

This study addresses the key scientific problem that the mechanical properties of barite concrete differ significantly from those of ordinary concrete due to the special material characteristics of high density and high brittleness of aggregates, and adopts the method of fine-scale mechanics to carry out a systematic study. Based on the non-homogeneous characteristics of concrete materials at the fine-scale, the uniaxial compression damage mechanism of barite concrete is investigated in depth by using three-dimensional fine-scale numerical simulation technology in an innovative way. Relying on ABAQUS finite element analysis platform, combined with the secondary development function of Python language, the study firstly adopts the improved Monte Carlo stochastic algorithm to generate a random polyhedral aggregate model conforming to the Fuller grading curve, and then realizes the accurate simulation of the shape, size and spatial distribution of the aggregates through the parameterized control; subsequently, a 3D fine-view numerical simulation of the concrete material containing three-phase components (barite aggregates, cement mortar matrix, and interfacial transition zone) is established. Subsequently, a three-dimensional finite element model containing three-phase components (barite aggregate, cement mortar matrix, and interface zone) was established, and finally, the complete damage evolution of barite concrete under uniaxial compressive loading was systematically investigated by applying the quasi-static displacement load and using the explicit kinetic analysis method. The study focuses on analyzing the initial microcrack germination location, crack expansion path, and final damage mode, revealing the influence of high-density aggregates on the damage mechanism of concrete. The research results not only improve the damage theory of barite concrete, but also provide an important theoretical basis and design reference for its application in radiation protection projects, counterweight structures and other special fields, which is of great scientific significance and engineering value for promoting the development of high-performance concrete.
