摘要
高掺量粉煤灰轻质节能免烧砖以粉煤灰为主要原料,加入部分陶粒、膨胀珍珠岩、砂、石粉等做骨料,并配以少量的钙质材料和微量的激发剂混合而成。通过优选原材料、配合比,设定合理的生产工艺等控制产品质量,其表观密度在1700～1900 kg/m3,强度等级不小于MU10,其他主要技术指标达到JC 2392-2001粉煤灰砖的标准。最后简单探讨了其增强机理。
The mixture ratio of lightweight energy-saving unburned brick with large mixed fly ash was studied that fly ash as raw materials, adding the partial ceramisite agitator, expanded perlite, sand, rock powder to make the aggregate, and being mixed with few calcareous materials and the micro excitant. We have controlled the product quality by selecting raw materials and mixture ratio, setting technique of production. Its apparent density in 1700-1900 kg/m3 strength grade of not less than MUI0, and other qualification have reached JC 2392-2001. Finally we have discussed its enhancement mechanism simply.
