摘 要:在球形粒子假设的基础上,采用计算机模拟方法研究了集料细度以及集料体积分数对相邻粗集料表面最近间距分布的影响。结果表明,相邻粗集料表面最近间距随集料体积分数的增加以及集料细度的增大而减小。 Abstract: Based on the hypothesis that the aggregate particles are spherical, a study of the influences of aggregate fineness and aggregate volume fraction on the nearest surface spacing distribution between neighboring coarse aggregate particles in model concrete has been down by using of computer modeling technology. The results show that the surface spacing decreases with the increasing of aggregate fineness as well as with the increasing of aggregate volume fraction.

在球形粒子假设前提下,采用计算机模拟方法初步探索了邻近粗集料表面最近的间距分布随集料细度以及集料体积分数的变化情况,结果表明,相邻粒子的表面最近间距随集料体积分数的增加以及集料细度的加大而减小。可为混凝土中集料分布的细观结构研究提供参考。
