【摘要】:通过Reax FF反应力场能量最小化方法优化了几种硅酸钙矿物的晶胞参数和原子坐标,采用径向分布函数及配位数的计算,分析了以硅酸三钙、硅酸二钙、硅灰石、假硅灰石、硅钙石和斜方硅钙石等为代表的硅酸钙矿物的晶体结构,从而揭示了不同钙硅比和不同硅氧四面体链接方式的矿物化学性质及水化活性差异的机制。
[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.
