自硬性是指粉煤灰在加水以后能自发的凝结硬化的特性.通过研究实验表明,CFBC脱硫灰具有良好的自硬性.因为它含有游离的CaO和CaSO4,可以激发脱硫灰中的SiO2和活性Al2O3,生成具有一定水硬性的凝胶类物质钙矾石AFt.而且它在自硬过程中凝结时间不长,本次实验中一般的初凝时间不超过1h,终凝时间不超过2h.自硬强度受化学成分、细度的影响非常大.化学成分中SO3和f-CaO含量对其影响较大：随着SO3含量的增加而自硬强度逐渐增加；而f-CaO含量有一个最佳值,过高反而导致自硬强度下降.降低细度有利于提高CFBC脱硫灰的自硬强度,当45µm筛余降到2.7%时,其7d自硬强度可达3MPa,28d自硬强度达15Mpa,同时粉磨过程还可以改善体积安定性.随着成型水灰比的降低,其自硬强度急剧升高.CFBC脱硫灰硬化浆体的膨胀率随着养护时间的延长而逐渐增加,并且通过粉磨可以降低其膨胀率,而且有利于膨胀的稳定.CFBC脱硫灰良好的自硬性,可以用于土壤加固、有毒物质的固化、做回填材料以及做新型胶凝材料等.

Will be refers to the pulverized coal ash from the rigidity later to be able spontaneous to congeal the hardened characteristic in the watering.Indicated through the research experiment that,the CFBC desulphurization ash has good from the rigidity.Because it includes CaO and CaSO4 which drifts away,may stimulate in the desulphurization ash SiO2 and active Al2O3,the production has certainly certainly congeals gummy substances matter ettringite AFt.Moreover it in the set time is not long from the hard process in,in this experiment is ordinary initially congeals time not ultra 2h,the time does not surpass 2h.From the hard intensity study ingredient,degree of fineness influence is extremely big.In chemical composition SO3 and f-CaO content to its influence bigger:But gradually increases along with the SO3 content increase from the hard intensity; But the f-CaO content has a best value,excessively high instead causes from the hard intensity to drop.Reduces degree of fineness to be advantageous to enhances the CFBC desulphurization ash from the hard intensity,when 45 um sieves Yu Jiangdao 2.7%,7d may reach 3MPa.28d from the hard intensity from hard intensity 15Mpa,simultaneously the powder rubs the process also to be allowed to improve the volume stability.Along with takes shape reducing,it suddenly elevates from the hard intensity.The CFBC desulphurization ash hardening hydromass expansion rate along with maintains the time to lengthen but gradually increases,and rubs through the powder may reduce its expansion rate,moreover is advantageous to the inflation stability.The CFBC desulphurization ash is good from the rigidity,may use in the strengthening of soil,the virulent material solidification,makes the backfill material as well as makes the new gel gelation gelling material and so on .
