Self-carbonization reinforced high-potassium Portland cement clinker as well as preparation method and application thereof
The invention relates to the technical field of Portland cement clinker preparation, and particularly discloses a self-carbonization reinforced high-potassium Portland cement clinker as well as a preparation method and application thereof. The cement clinker is prepared from the following mineral components in percentage by mass: 15.97% to 18.35% of C3S-M1, 35.83% to 36.34% of C3S-M3, 18.99% to 20.57% of C2S-alpha 'L, 1.3% to 2% of C2S-beta, 0.09% to 0.72% of C3A-c, 12.71% to 15.33% of C3A-o, 9.24% to 10.91% of C4AF and 1.28% to 1.48% of secondary free CaO. According to the invention, the harm of skinning and ring formation caused by alkali-sulfur circulation is reduced; and by utilizing the difference of the hydration rates of C2S-alpha 'L and C3A-o, the clinker system can continuously release K < + > ions without concentration after being contacted with water, so that the alkalinity in the hydration process is not reduced, a good alkaline environment is provided for carbonization, and the mechanical strength is improved.
本发明涉及硅酸盐水泥熟料制备技术领域,具体公开一种自碳化增强高钾硅酸盐水泥熟料及其制备方法与应用。按质量百分比计,所述水泥熟料的矿物组成包括:C3S‑M1 15.97~18.35%、C3S‑M3 35.83~36.34%、C2S‑α’L 18.99~20.57%、C2S‑β 1.3~2%、C3A‑c 0.09~0.72%、C3A‑o 12.71~15.33%、C4AF 9.24~10.91%、二次游离CaO 1.28~1.48%。本发明不仅降低了碱硫循环所带来的结皮结圈的危害,而且利用利用C2S‑α’L和C3A‑o由于其水化速率的差异,使得孰料体系在与水接触后可以持续但不集中的释放K+离子,保证了水化过程中的碱度不会降低,为碳化提供良好的碱性环境,提高了力学强度。
