Mathematical Model and Test Study of Aggregate Gradation on Particulate-Reinforced Composite

Aggregate gradation of particulate-reinforced composites was analyzed with mathematics model and test. The results showed that: We can obtain the prior way of aggregate gradation with appropriate ratio of large particle quartz sand and small particle quartz sand, which can make the void ratio of gradation and specific surface of quartz sand lesser, lower the quantity of resin, so as to reduce the cost and improve the economic benefits, and the mathematical model and experimental results are in good agreement in the same time.
