Abstract

The invention relates to a method for producing a prefabricated member of a concrete ditch by using coal gangue. The method is characterized in that the prefabricated member of the concrete ditch is prepared from the following raw materials in parts by weight: 50-60 parts of coarse and fine aggregates, 5-10 parts of coal gangue powder, 10-15 parts of 42.5 sulfoaluminate cement, 2-5 parts of early strength agent, 2-5 parts of thickening and reinforcing agent, 1-3 parts of efficient water reducing agent and 0.1-0.5 part of antifoamer, wherein the efficient water reducing agent is a calcium lignosulfonate water reducing agent. According to the method, the prefabricated member of the concrete ditch is low in cost, excellent in performance and stable in quality and has excellent compressive strength and antifreeze and impervious performance; and the standardized construction of farmland water conservancy is further strengthened, the construction level and management level of farmland water conservancy projects in China are comprehensively increased, the utilization ratio of irrigation water is increased, and the efficient utilization of water resources is achieved.

Description

technical field [0001] The invention belongs to the field of concrete processing, and in particular relates to a method for producing concrete trench prefabricated parts by utilizing coal gangue, which can be widely used in agricultural engineering and water conservancy construction engineering. Background technique [0002] China is a developing country that uses coal as its main energy source. Coal accounts for more than 70% of primary energy consumption, which is more than double the world average. The energy structure is still dominated by coal. Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. Including the excavation gangue during the roadway excavation, the gangue extracted from the roof, floor and interlayer during the mining process, and the gangue picked out during the coal washing p...
