Abstract

The invention discloses a composite gel material taking bulk solid waste as a raw material. The composite gel material is prepared from the following raw materials in parts by weight: 40-50 parts of iron tailings, 5-10 parts of blast furnace slag, 10-20 parts of fly ash, 20-30 parts of desulfurized fly ash, 20-30 parts of carbide slag and 0.05-0.14 part of an activating agent. According to the invention, a large amount of industrial bulk solid waste can be consumed, environmental pollution can be reduced, a large amount of fertile farmland clay is saved, waste is turned into wealth, and high-efficiency utilization of the industrial bulk solid waste is realized; and the composite gel material is simple in production process, low in cost and high in quality.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling, and in particular relates to a composite gel material using bulk solid waste as a raw material and a preparation method thereof. Background technique [0002] In recent years, many scholars have carried out a series of researches on the current situation of single filling cementitious material and high filling cost. Lu Qianming et al. used papermaking sludge ash and sulphoaluminate cement clinker to prepare coal mine filling cementitious materials, and studied the effects of suspension thickeners, activators, and slurry water-solid ratios on the strength, water retention, and fluidity of cementitious materials. And using X-ray diffraction, scanning electron microscopy and energy spectrum analysis to analyze the hydration products microscopically, the prepared filling cementitious material can meet the requirements of pumping and strength at the same time; Li Gaolu et al. used fly as...
