Abstract

The invention relates to a method for producing light high-strength artistical cast stone from coal ash, aiming to effectively solve the problems of high energy consumption and high pollution in the process of producing the artistical cast stone and the problem that the waste coal ash discharged by a coal-fired power plant in power generation cannot be utilized effectively. The technical solution is as follows: the method comprises the steps of die painting, blank fabrication, moulding, steam curing, demoulding, drying and packaging. The method has the following advantages: a coal ash-alkali-calcium sulfate stimulation system is employed to stimulate the activity of the coal ash, and simultaneously, the grading of the mixture is adjusted, so that the comprehensive utilization of the coal ash is promoted and the industrial energy consumption is reduced; the coal ash is applied to the production of the artistical cast stone for the first time; and in this way, energy is saved and emission is reduced, the coal ash is comprehensively utilized and the defect of insufficient activity of the coal ash is overcome. Besides, the production cost is reduced, the product performance is improved and good social and economical benefits are produced.

Description

technical field [0001] The invention relates to the technical field of building material manufacturing, in particular to a method for manufacturing lightweight high-strength artistic pouring stone by using fly ash. Background technique [0002] The industry uses cement, ceramsite and admixtures as raw materials for making artistic pouring stones, but both cement and ceramsite require high-temperature calcination, which is a high-energy-consuming and high-pollution industry. [0003] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. Fly ash is one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. The problem of the treatment and utilization of fly ash has attracted widespread attention. my country is a large coal-producing country, and coal is used as the b...
