本文旨在研究利用生产斑岩和白云石石灰石产生的粉尘和污泥作为波特兰熟料窑的替代原料，并列举了可能的局限性。研究了生产成分变化稳定的原料的可能性，并进行了模拟，以最大限度地利用它们在熟料窑中的使用。此外，实验熟料的生产剂量被数值模拟认为是真实的。根据可能的矿物学影响对最终熟料进行了全面的分析和评估。
This paper aims to examine the use of fines and sludge generated out of the production of porphyry and dolomitic limestone as an alternative raw material for Portland clinker kilns with enumeration of possible limitations. The possibility to generate a raw material with a stable compositional variation was investigated and simulations were carried out to maximise their use in clinker kilns. Furthermore, experimental clinkers were produced with dosages that were esteemed as realistic by the numerical simulations. The final clinkers were fully analysed and evaluated on possible mineralogical influences.
