Effect of the Concrete Mesostructure Geometric Form on Its Elastic Modulus

摘要: A comprehensive understanding of the geometrical form concrete mesostructure is important because it associated with complex and random mechanical behavior concrete. There still uncertainty about how to characterize its effect on observed macroscopic behavior. The coarse aggregate content fractal dimension were used in this study indicate at mesolevel. Taking parameters measured experiments, a group mesomodels various dimensions contents was simulated by using modeling method then studied discussed. analytical solution, simulation, experimental data all suggested that elastic modulus increased increasing content. Meanwhile, can cause decline slightly. consideration both geometry classical Euclidean aid predicting
