摘要
评述颗粒堆积模型的基本理论、发展及其最新应用.对比分析多种颗粒堆积模型间的差异,指出颗粒堆积模型的主要优点、局限性及其在复合颗粒体系材料领域中的应用范围.分析表明,利用颗粒堆积模型优化计算混凝土的堆积密实度,可以降低复合颗粒体系间的空隙体积,使颗粒系统达到最紧密堆积状态,减少混凝土中胶凝材料的用量,实现低胶凝材料用量绿色混凝土优化设计.
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 accumula- tion 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.
