For the cement, the surface hydration is the primary process at the initial stage, the kaolin disorganizes and gets into the solution in the form of the silicate tetrahedron and aluminate tetrahedron at the induce stage; the silicon-aluminum tetrahedron network structure is formed at the accelerate stage; the unti-network structure is formed and the rate of heat evolution falls at the decelerate stage; the reaction finished ultimately at the stable stage.

但其水化机理与传统的硅酸盐水泥不同：初始期主要是表面水化，诱导期是高岭土解体并以硅氧四面和铝氧四面体的形式进入液相；加速期形成硅铝四面体网络结构；减速期网络基本形成，水化放热速率降低；稳定期反应速率很低，网络结构趋于稳定。

If they were initially thwarted by allegedly indestructible siding made of aluminum, vinyl, or the maintenance-free, portland-cement-cellulose-fiber clapboards known as Hardie planks, they merely have to wait a century before most of it is lying on the ground.

如果它们最初被阻挡在所谓的坚不可摧的墙板外面——这种墙板由铝、乙烯化合物构成，也可能由被称为&高能厚壁板&、无需保养的硅酸盐水泥纤维隔板构成——它们所要做的不过是等上一个世纪，那么大部分的人工材料都会不攻自破了。
