Abstract

Based on a simplified theoretical design method which took the objective void ratio in coarse aggregates (VCAobj) as the index, three different gradation designs with VCAobj of 35% were proposed in this paper. Through the PFC2D software, both the loading and force transferring were simulated on a micro level of the gradation of aggregate skeleton. During the orthogonal tests for the optimized gradation design, three factors (cement aggregate ratio, water cement ratio and recycled aggregate content) were analyzed to draw the conclusion of their influence on the 28th day's compressive strength and effective void ratio.
