粉煤灰是火力发电厂煤粉燃烧后产生的废渣。大量废渣被送至贮灰场或排入江河湖海,污染了水源和环境。为了综合利用粉煤灰,山西省第四建筑公司对蒸养粉煤灰加气混凝土进行了试验研究、扩大试验、试生产和工程应用。一、试验研究 1.原材料 (1)粉煤灰:太原市北郊第二热电厂湿排粉煤灰,细度为△900孔,筛余10％。 (2)水泥:大同425号普通硅酸盐水泥。 (3)生石灰为太原东涧河产石灰。
Fly ash is the waste residue from the combustion of pulverized coal in thermal power plants. A large amount of waste residue is sent to the ash yard or discharged into rivers, lakes and seas, polluting the water source and the environment. In order to make comprehensive use of fly ash, Shanxi No. 4 Construction Co., Ltd. conducted experimental research, expanded tests, pilot production and engineering applications for steamed fly ash aerated concrete. I. Experimental research 1. Raw materials (1) Fly ash: The wet discharged fly ash from the second thermal power plant in the northern suburbs of Taiyuan City has a fineness of △900 holes and a sieve of 10%. (2) Cement: Datong No. 425 Ordinary Portland Cement. (3) Lime is lime produced by Dongyuan River in Taiyuan.
