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 .
