摘要
文章采用超细粉煤灰与硅灰的复合技术配制多孔水泥混凝土水泥浆体试件。通过与双掺硅灰和减水剂、双掺粉煤灰和减水剂以及复合掺粉煤灰、硅灰和减水剂的情况对比,系统研究了硅灰粉煤灰作为外掺挤对多孔水泥混凝土水泥浆体的强度的影响。实验结果表明,由于硅灰与超细粉煤灰的复合,在水泥浆体形成过程中,这2种材料充分发挥了各自的功能效应,使得多孔水泥混凝土水泥浆体的强度性能显著提高。文章通过扫描电镜试验,剖析了超细粉煤灰与硅灰复合效应的机理,论证了用超细粉煤灰和硅灰以及减水剂复合配制多孔水泥混凝土水泥浆体的可行性。
This paper adopts the composite technology of ultra-fine fly ash and silicon ash to collocate the cement paste specimen of porous cement concrete. According to the comparison of the condition of double-add silicon ash and water-reducing agent, double-add fly ash and water-reducing agent, as well as composite mixed fly ash, silicon ash and water-reducing agent, the author systematically analyzes the impact on the paste strength of high performance porous cement concrete, which is caused by fly ash and silicon ash as additives. The experimental results demonstrates that in the process of cement paste,as a result of the the composite of ultra-fine fly ash and silicon ash, these two materials fully play respective functional effect to obviously enhance the strength of the cement paste of porous cement concrete. Through the scanning electron microscopy test, this paper analyzes the mechanism of ultra-fine fly ash and silicon ash composite effect, it also argues the feasibility of using ultra-fine fly ash, silicon ash and water-reducing agent to collocate the cement paste specimen of porous cement concrete.
