颗粒堆积模型在混凝土中的应用
Application of particle packing model in concrete
摘要
Abstract
The main advantages and limitations of particle packing models,as well as their applications in the field of composite particle systems are pointed out by comparing and analyzing the differences among various particle packing models.The analysis show that,in order to reduce the void volume and achieve the most compact accumulation state of the composite particle system,the particle packing model can be used to calculate the packing density,thus the volume of cementitious materials in the concrete can be reduced and the optimal design of low binder green concrete can be realized.关键词
