中文摘要：

我们调查了裂开和 ferro 硅质、硅质的原子牺牲的水泥的脱离行为的模拟。到这个目的，牺牲的水泥的四种类型被制作， i e， ferro 硅质的(F) 和硅质的(S) 平原水泥，和聚丙烯纤维增强了上面的水泥二(FF， SF ) 。裂开和牺牲的水泥的脱离行为被模拟测试调查，并且模仿的提高的温度借助于铝热剂粉末被获得。数字和裂缝的宽度被比较，牺牲的水泥的毛孔尺寸分发被测量。另外，接口和化学作文融化在不同位置被分析，并且牺牲的具体坩锅的脱离深度也被测量。硅质的水泥出现是对由于苍蝇灰和更低的水的更高的内容比 ferro 硅质的水泥裂开到文件夹比率敏感的更多，这被发现；尽管硅质的水泥的脱离深度被发现稍微更大，没有清楚的差别能为 basemat 脱离率被检测。

英文摘要：

We investigated the simulation of the cracking and ablation behavior of ferro-siliceous and siliceous nuclear sacrificial concretes. To this end, four type of sacrificial concretes were fabricated, i e, the ferro-siliceous（F） and siliceous（S） plain concretes, and the polypropylene fiber reinforced concretes of the above two（FF, SF）. The cracking and ablation behaviors of the sacrificial concretes were investigated by simulation tests, and the simulated elevated temperature was obtained by means of thermite powder. The number and the width of the cracks were compared and the pore size distribution of sacrificial concretes was measured. In addition, the interface and chemical composition of melt at different positions were analyzed, and the ablation depth of the sacrificial concrete crucibles was also measured. It was found that the siliceous concrete shows to be more prone to cracking than the ferro-siliceous concrete due to the higher content of fly ash and lower water to binder ratio; though the ablation depth of siliceous concrete is found to be slightly larger, no clear difference can be detected for the basemat ablation rate.
