摘要/Abstract

摘要： 超硫酸盐水泥(SSC)中石膏存在最佳掺量,纳米二氧化硅(NS)虽然可以提高超硫酸盐水泥强度,但是对石膏与铝相水化反应具有抑制作用,导致石膏最佳掺量发生改变。因此,探究NS改性条件下的石膏最佳掺量,有望进一步提高SSC性能。本文通过改变掺入与未掺入3%(质量分数)NS的SSC中石膏掺量(5.0%~15.0%,质量分数),研究其对SSC力学性能及微观性能的影响。结果表明,未掺加NS时,SSC整体强度发展缓慢,反应1 d时,强度随石膏掺量的增加呈下降趋势,石膏最佳掺量为7.5%。掺入NS后,SSC强度显著提升,3～28 d强度增幅达100%~200%,石膏最佳掺量呈增加趋势,当石膏掺量为15.0%(本文设计最大掺量)时,强度最大。NS延缓石膏消耗,抑制钙矾石生成,但不影响最终石膏消耗量;加入NS后,SSC化学结合水含量、石膏消耗量呈增加趋势,表明体系对石膏的需求量增加。本文通过探究NS改性SSC中的石膏最佳掺量变化,为进一步降低矿粉用量、提高SSC绿色低碳性提供新思路。

Abstract: There is an optimum gypsum content in supersulfate cement (SSC), although nano-SiO₂ (NS) can effectively improve the strength of SSC, but it can inhibit the hydration reaction of gypsum and aluminum phase, and the optimum gypsum content is changed. So optimizing the content of gypsum in the system is expected to further improve the performance of SSC. In this paper, the effect of mixing with or without 3% (mass fraction) NS on the mechanical and microscopic properties of SSC with gypsum content (5.0%~15.0%, mass fraction) was studied. The results show that the overall strength of SSC without NS develops slowly, the strength shows a downward trend with the increase of gypsum content at 1 d, and the optimum gypsum content is 7.5%. When NS is added, the strength increases significantly, the 3~28 d strength increases 100%~200%, the optimum gypsum content shows an increasing trend and the maximum strength is obtained when the gypsum content is 15.0% (the maximum content designed in this paper). NS lags gypsum consumption rate and inhibits ettringite formation, but does not affect the final consumption of gypsum. After the addition of NS, the chemical binding water content and gypsum consumption of SSC show an increasing trend, indicating that the demand for gypsum in the system increases. By exploring the change of the optimal gypsum content in NS-modified SSC, this paper provides new ideas for further reducing the amount of mineral powder, and improving the green and low carbon properties of SSC.
