The result of the experiments shows that the effects of compound pozzolanic and micro - aggregate have been produced when silica fume and slag were added into concrete together . and the stone enveloped with cement can meliorate distinctly the structure of the transition zone of interface , thus the strength of concrete is improved 试验结果表明：在混凝土中同时掺入硅灰和矿渣可以产生复合火山灰效应和微集料填充效应； “净浆裹石”搅拌工艺可以大大改善界面过渡区结构，从而提高混凝土的强度。
The facial and pore properties of lightweight aggregate and transition zone of lwac is studied by the means of sem and xrd . it is concluded that the " embedded " transition zone of lightweight aggregate - paste makes the principle contribution to the higher early strength of lwac . meanwhile , the " internal curing " of the double pore structure in lwac has been proved 本文利用xrd和sem等现代测试手段对轻集料的表面和孔特性以及轻集料和水泥石的界面结构进行了系统研究，揭示了轻集料和水泥石的“嵌套”界面结构是轻集料混凝土早期强度高的根本原因和轻集料对水泥石的“自养护”作用规律。
And as the number of ecap passes increases , the rate at which softening occurs in the transition zone increases and the onset temperature of recrystallization drops . moreover , the grain size after static recrystallization is more finer , so grain size can be further refined by controlling the temperature and time of recrystallization Ecap道次越多，再结晶的温度越低，再结晶软化的速度越快，而且再结晶后的晶粒尺寸更为细小，因此可以通过控制再结晶的温度和时间进一步细化晶粒。
