Embodiment 1
[0022] see figure 1 As shown in the present invention, a method for producing degradable blocks by utilizing industrial and agricultural wastes, the wastes are composed of waste ceramics, corn stalks and sodium hydroxide, and the mass percentages thereof are as follows:
[0023] Waste ceramics: 65%. Corn stover: 33%. Sodium hydroxide: 2%
[0024] Among them, waste ceramics are selected as waste ceramic floor tiles. In the chemical composition of waste ceramics, the mass percentage content of SiO2 is 67.2%, the mass percentage content of Al2O3 is 17.5%, the mass percentage content of Na2O is 2.1%, and the mass percentage content of K2O is 2.2%. The moisture content of corn stover is 8.6%.
[0025] The production method of degradable block is:
[0026] Pulverize the waste ceramics and grind them to a particle size of no more than 300μm, pulverize the corn stalks that meet the moisture content requirements to a particle size of no more than 300μm, then accurately weigh the m...

Abstract
The invention relates to a method for producing degradable building blocks by utilizing industrial and agricultural wastes. Belongs to the technical field of energy conservation. According to the building block, ceramic waste meeting the chemical component requirement and corn straw meeting the water content requirement serve as raw materials, and the building block can be used after being subjected to smashing, metering, stirring, high-temperature pressing forming and room-temperature cooling. Industrial and agricultural wastes which originally become environmental problems are reasonably developed and utilized, and the problem of environmental pollution is solved. The building block prepared by the invention does not contain cement, is low-carbon and environment-friendly, and has the characteristics of high compactness and degradability compared with a common concrete building block.
Description
technical field [0001] The invention relates to a method for producing degradable blocks by utilizing industrial and agricultural wastes, and belongs to the technical field of energy conservation and environmental protection. Background technique [0002] At present, the blocks used in building walls are mostly made of cement, fly ash, sand, etc. Cement production accounts for 8 percent of the world's carbon dioxide emissions, and raw materials such as sand are already hard to come by in some places. On the other hand, the discharge of ceramic waste from ceramic production and decoration and dismantling is considerable, and corn stalks produced in agricultural production are incinerated in some cases, and improper disposal is likely to cause environmental pollution. The use of industrial and agricultural waste to produce degradable blocks can save resources, be green and environmentally friendly, and can be recycled after the end of the service life; it not only meets the o...
