针硅钙石

The traditional ceramic semifinished materials are the aluminum silicate system, the production phase are mainly the mullite, the solid phase reaction temperature are quite high, generally in 1200℃ about; But after joining the wollastonite, turns the calcium silicate system, the high temperature resultant for the anorthite and the cristobalite, reduced the solid phase reaction temperature largely, approximately for 1000℃~1050℃, and the anorthite assumes acicular.

传统的陶瓷坯料为硅酸铝系统，生成的物相主要为莫来石，固相反应温度比较高，一般在1200℃左右；而加入硅灰石后变成硅酸钙系统，高温生成物为钙长石和方石英，大幅降低了固相反应温度，大约为1000℃～1050℃，且钙长石呈针状。

Adding silica sand to cement whose temperature ranges from 110～150℃or maintaining it in 110℃about three days, cement can form the fiber C5S6H5. After temperature above 150℃, it form thick needle C6S6H which can to some extent effectively curb the high-temperature recession of cement strength.

在水泥中加入硅砂时，在110～150温度范围内，或110℃养护时间超过3天，水泥石中分别出现了由纤维针状结晶C5S6H5，温度超过150℃后，又出现粗大针状结晶硬硅钙石C6S6H，这两种产物在一定程度上有效地抑制水泥石强度的高温衰退现象。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
