Embodiment 1-3
[0018] The main raw materials are desulfurization gypsum, waste incineration fly ash, limestone, bauxite. The main chemical components of the raw materials are shown in Table 1.
[0019] Table 1 Chemical Composition / wt% of Raw Materials
[0020]
[0021] Calculated according to the designed mineral clinker composition: garbage ash: 20%; limestone: 31%; desulfurized gypsum: 19%; bauxite: 30%. The raw materials in the above ratio were calcined in an electric furnace at 1200° C. for 1 hour at a heating rate of 30° C. / min, and then taken out for rapid cooling. The chemical composition of the sulfoaluminate clinker is shown in Table 2.

Abstract
The invention relates to a method for preparing an underwater rapid leaking stoppage material from industrial waste residues. The industrial waste residues comprise waste incineration ash, fly ash andthe like. The method comprises the following steps: (1) calcining a quick-hardening cement-based material, namely heating a raw material prepared from waste incineration fly ash to 1200-1250 DEG C inan electric furnace at a heating speed of 20-30 DEG C / min, keeping the temperature for 1-2 hours to prepare a quick-hardening sulphoaluminate cement clinker, and mixing the clinker with anhydrous gypsum to obtain sulphoaluminate cement; and (2) preparation of the quick-hardening cement-based underwater leaking stoppage material: mixing sulphoaluminate cement, quartz sand, fly ash, hydroxypropyl methyl cellulose ether, redispersible rubber powder and fibers to obtain the underwater leaking stoppage material. Compared with the prior art, the method has the advantages that the product performance is guaranteed, and meanwhile, the serious burden and the treatment cost of the environment due to the fact that fly ash, desulfurized gypsum and the like are not utilized can be reduced.
Description
technical field [0001] The invention belongs to the field of new material technology, environmental protection and energy saving technology, and relates to the utilization of industrial waste residues such as waste incineration fly ash and the production of an underwater rapid plugging material. Background technique [0002] With the rapid development of urban construction and rapid population growth, the discharge of municipal solid waste is also increasing sharply, and its composition is becoming more and more complex. Taking domestic waste as an example, the national urban domestic waste removal volume was only 53.98 million tons in 1987, and it soared to 120 million tons in 1997. In 2002, my country's urban waste has reached more than 150 million tons, and the annual rate is 8% to 10%. The speed is increasing, and it is estimated that by 2010, the annual discharge of municipal solid waste in my country will reach 210 million tons. These wastes pose a serious threat to th...
