Alite-ye'elimite cement (ACSA) was synthesized by single firing process at lower temperature with addition of phosphorous slag and copper slag, which could be a promising low-energy Portland cement. The coexistence of alite and ye’elimite in this clinker can improve the cement quality and their coproduction during clinkering is crucial. Thus, in order to modify the mineralogical phase composition and its chemical industrial process during the clinker sintering, the kinetics of alite formation and ye’elimite decomposition processes were studied by XRD Rietveld refinement method in this work. Results showed that, during the alite formation and Ye’elimite decomposition processes, Ginstling-Brounshtein diffusion model can be employed to determine their apparent activation energy. The activation energy of ye'elimite decomposition with temperature lower and higher than 1275 °C are 230.4 kJ/mol and 998.9 kJ/mol, respectively. The activation energy of alite formation is temperature dependent in a piecewise function divided by 1278.5 °C. The key to make alite and ye’elimite better coexisted in cement production could be controlling the acquisition of CaO during alite formation and hindering the diffusion of CaO to contact with Ye’elimite during decomposition.

Alite-ye'elimite 水泥 (ACSA) 是通过添加磷渣和铜渣在较低温度下通过单烧法合成的，它可能是一种很有前途的低能硅酸盐水泥。在这种熟料中，alite 和 ye'elimite 的共存可以提高水泥质量，在熟料过程中它们的联产至关重要。因此，为了改变熟料烧结过程中的矿物相组成及其化学工业过程，本工作采用XRD Rietveld精修方法研究了alite形成和ye'elimite分解过程的动力学。结果表明，在alite形成和Ye'elimite分解过程中，可以采用Ginstling-Brounshtein扩散模型来确定它们的表观活化能。ye'的活化能 温度低于和高于 1275 °C 时的极限分解分别为 230.4 kJ/mol 和 998.9 kJ/mol。alite 形成的活化能与温度有关，呈分段函数除以 1278.5 °C。在水泥生产中使阿利特和叶氏剂更好地共存的关键可能是在阿利特形成过程中控制 CaO 的获取，并在分解过程中阻止 CaO 扩散到与叶氏剂接触。
