This problem dates back to 1611, when Johannes Kepler conjectured that the best packing arrangement for identical spheres was arranging them in what is now called face centered cubic packing - similar to how one sees cannon balls stacked.

这个问题可追溯到1611年约翰尼斯·开普勒提出堆积等大球体最佳方法的猜想（译者注：当等大球体按照--球心位于正方体各面的中心上--的形式，并且将第一层摆放成六角形时，它们占用的空间最小，对空间的利用率可以超过74%），现在把这个方法叫做面心立体堆积法--类似于加农炮弹的堆积方式。1998年，安娜堡密西根大学教授托马斯·C·黑尔斯证明了这个猜想。

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.

由图象分析可知，即C原材料的比例及颗粒度符合密实堆积原理，堆积物的孔隙率达到最小；差示扫描量热分析表明，RPC的水化反应速度很快，主要的水化过程集中在较短时间内；扫描电镜及X衍射试验表明，RPC硬化体的结构非常致密，主要由一些不规则状的扁平粒子紧密堆积在一起，水化产物主要是Ⅲ型C-S-H， Ca2晶体的量稀少且没有钙矶石。
