【摘要】:通過Reax FF反應(yīng)力場能量最小化方法優(yōu)化了幾種硅酸鈣礦物的晶胞參數(shù)和原子坐標,采用徑向分布函數(shù)及配位數(shù)的計算,分析了以硅酸三鈣、硅酸二鈣、硅灰石、假硅灰石、硅鈣石和斜方硅鈣石等為代表的硅酸鈣礦物的晶體結(jié)構(gòu),從而揭示了不同鈣硅比和不同硅氧四面體鏈接方式的礦物化學性質(zhì)及水化活性差異的機制。
[Abstract]:The unit cell parameters and atomic coordinates of several kinds of calcium silicate minerals were optimized by Reax FF reaction force field energy minimization method. Using radial distribution function and coordination number calculation, the authors analyzed the effects of tricalcium silicate, dicalcium silicate, wollastonite and pseudo-wollastonite. The crystal structure of calcium silicate minerals represented by silicalite and clinicalite reveals the mechanism of the difference of mineral chemical properties and hydration activity of different calcium / silicon ratios and different Si-O tetrahedron linking modes.
