Chemically-excited sulfur-fixing ash-based foam light soil
The invention relates to chemically-excited sulfur-fixing ash-based foam light soil which is prepared from the following raw materials in parts by mass: 88-165 parts of sulfur-fixing ash, 260-293 parts of cement, 29-55 parts of fly ash, 0.4-0.5 part of an excitant, 0.7-0.8 part of a foaming agent and 180-190 parts of water. According to the method, the solid waste sulfur-fixing ash of a thermal power plant is applied to the foamed light soil for the first time, a feasible method is provided for solving the stockpiling problem of the sulfur-fixing ash, and utilization and development of the clean energy technology of circulating fluidized bed combustion are promoted. The fly ash and the sulfur-fixing ash are mixed, so that the expansibility of the sulfur-fixing ash-based light soil can be reduced, the expansion stable period of the sulfur-fixing ash-based light soil is advanced, and the damage of the expansibility of the sulfur-fixing ash to the foamed light soil is reduced.
本发明涉及一种化学激发的固硫灰渣基泡沫轻质土，以质量份数计，由以下几种原料制成：固硫灰渣88～165份、水泥260～293份、粉煤灰29～55份、激发剂0.4～0.5份、发泡剂0.7～0.8份以及水180～190份。本发明首次将热电厂固体废物固硫灰渣应用于泡沫轻质土中，为解决固硫灰渣的堆存问题提供了一种可行的方法，促进循环流化床燃烧这种清洁能源技术的利用与发展。本发明采用粉煤灰与固硫灰混掺，可降低固硫灰渣轻质土的膨胀性并且使固硫灰基轻质土的膨胀稳定期提前，减小因固硫灰渣膨胀性对泡沫轻质土造成的破坏。
