摘要
为防治火电厂贮灰场扬尘污染对粉煤灰固技术进行了试验研究。目前已研制出２个系列的粉煤灰固结剂，固结后的抗压强度都在１６ｋｇ／ｃｍ２以上，最高达７０ｋｇ／ｃｍ２；水稳系数和冻稳系数都在０．９０—１．００。该项技术具有抑尘效果好、保持时间长、治理成本低、原料来源广泛、施工工艺简单和易于推广等待点。它可用于正在使用的灰场（包括中转灰场、碾压灰场）和贮满灰的灰场治理扬尘，还可用于灰场防渗和灰坝加固。
Test and research have been made on a solidification technology for pulverized ash to be used in suppressing dust of ash ponds or landfills for coalfired power plants. As a result, two series of ashstabilizing agent have been already developed.The solidified ash has a compressive strength over 16 kg/cm2, with a maximum of 70 kg/cm2, and stability coefficients in water and in freezing state are over 0.90 and even up to 1.00. This process is highly efficient in dust suppression, durable in operation, low in cost, abundant in raw material supply, simple in applicatioll, and easy in popularization. It can be used for ash ponds or landfills in operation or being full, for reinforcing ash dykes and for preventing permeation of ash ponds.
