Coarse aggregate size distribution is important for the research on concrete strength analysis. Usually it can not be obtained without cutting a part of concrete down.
粗骨料粒径分布对混凝土强度分析有重要影响，但如果不用切割方法，混凝土内粗骨料三维粒径分布测量就无法实现。
Because of vast volume of a dam, the coarse aggregate of concrete used for constructing a dam is of large grain size and more grading.
由于水坝的体积大，用来筑坝的混凝土的粗骨科粒径大、分级多。合理确定最大粒径、分级尺寸和级配十分重要。
The curing condition, the maximum size of coarse aggregate and silica fume have certain effects on the strength, fracture properties and brittleness of concrete.
养护条件，粗骨料最大粒径和硅灰对混凝土的强度，断裂性能和材料脆性都有一定影响。
