Abstract

The results of studies of the influence of dust from electrostatic precipitators of cement kilns on the synthesis of a binder containing mainly dicalcium silicate are demonstrated. The presence of alkali potassium and sodium oxides, as well as sulfate ions in the dust of electrostatic precipitators during annealing of a carbonate-siliceous mixture, promotes the formation of a solid solution based on the structure of β-modification 2СаО‧SiO₂, an increase the defectiveness of its crystal lattice, maintaining a metastable state during cooling and a rise in activity under hydrothermal conditions of hardening.

水泥窑静电除尘器中含尘合成硅酸二钙

摘要

证明了水泥窑静电除尘器产生的粉尘对合成主要含有硅酸二钙的粘合剂的影响的研究结果。碱钾和钠的氧化物，以及在静电除尘器的灰尘硫酸根离子的碳酸盐硅质混合物的退火过程中的存在，促进了固体溶液的基于β改性的2СаО‧SiO的结构中形成₂，一个会增加其晶格的缺陷，在冷却过程中保持亚稳态，并在硬化的水热条件下提高活性。
