固硫灰制备灌浆材料的试验研究

Test Study on Grouting Materials Preparation by Fluidized Bed Combustion Ash

以燃煤发电厂固体废弃物流化床固硫灰作为水泥基灌浆材料的掺合料,利用燃煤固硫灰火山灰活性、自硬性降低水泥基灌浆材料的水泥用量,利用其膨胀性,减少甚至不使用膨胀剂,配制出低成本并符合国家标准要求的灌浆材料。

Grouting material meeting the requirements and with low cost is prepared through using the solid waste of coal plant-fluidized bed combustion ash as cementitious admixtures, which can reduce the cement content because of its self-hardening and can reduce or even not use the expansive agent because of its expansion.
