Problems solved by technology

[0004] At present, my country's treatment of ceramic waste and granite waste is mainly through simple landfill methods. Ceramic waste and granite waste are dust wastes. If they are directly buried without treatment, they will cause serious pollution to the air. Haze weather, causing secondary pollution, affecting people's health and causing harm to the environment

Embodiment 1

[0039] The waste porcelain mud produced in the process of ceramic production is dehydrated into solid waste and damaged blanks, damaged waste products that have not been calcined and glazed, semi-finished products that have been calcined and glazed, waste products with damage or cracks, construction waste ceramics and sanitation The mixture of waste ceramic residues is crushed, sorted, pulverized, and magnetically separated to remove waste metals, and then dried, wheel-milled and sorted to make a powder with a particle size of less than -10mm;

[0040] A kind of volcanic ash-like mixed material formed by burning coal at high temperature to generate electricity is a kind of solid waste discharged from coal-fired power plants. The fineness is generally below 45um and then dried and screened to make fly ash powder.

[0041] The fine powder and leftover waste produced by the granite processing plant in the process of producing and cutting granite are crushed, sorted, pulverized, an...

Embodiment 2

[0044] Get the ceramic waste slag powder 55kg of embodiment 1, fly ash 20kg, granite waste slag powder 25kg, Portland cement 20kg, particle diameter is the unslaked lime powder 12kg of-0.2mm, gypsum powder 6kg, polycarboxylate high-efficiency 1.0kg of water reducing agent, 1.2kg of sodium carbonate, 0.6kg of calcium formate, 0.5kg of sodium sulfate and 18kg of water. The above raw materials are mixed with a twin-shaft mixing mixer until they are moist, and then extruded by mechanical vibration. Manufactured under a pressure of 28Mpa The molded ceramic waste lightweight hollow block has a specification of 390mm×140mm×190mm. It is cured at natural temperature, and then is naturally dried and cured at room temperature for 28 days by water spraying method to make the ceramic waste light-weight non-fired hollow block product. The average value of the tested compressive strength is: 6.8Mpa, and the minimum value of a single block is: 5.2Mpa, which is a qualified product.

Abstract

The invention relates to light non-fired hollow building blocks produced from ceramic waste residue and a manufacturing method thereof. The light non-fired hollow building blocks are characterized in that: the light non-fired hollow building blocks are prepared from the following raw materials: the ceramic waste residue, flayash, granite waste residue, portland cement, quick lime powder, gypsum powder, a polycarboxylate high-efficiency water reducing agent, sodium carbonate, calcium formate, sodium sulfate and water; and the manufacturing method comprises the following steps of: stirring the raw materials into a moist state with a blender, extruding and forming through mechanical vibration, manufacturing the ceramic waste residue light non-fired hollow building blocks under the pressure of between 25 and 30MPa, and naturally drying and curing for 28 days at normal temperature by a water spraying method to prepare the products. The raw materials of the invention can also be made into crown wall bricks, paving tiles and sidewalk tiles with different specifications. The products have the advantages of light weight, high strength, no pollution, low cost and good benefit, and meet the national economic requirements of energy conservation, emission reduction and low carbon.

Description

technical field [0001] The invention relates to a light-weight non-fired hollow block produced by ceramic waste residue, specifically, it uses ceramic waste residue and granite waste residue as main raw materials after crushing, sorting, pulverizing and sorting. The light-weight burning-free hollow block produced belongs to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the lightweight unfired hollow block. Background technique [0003] Ceramic waste slag is waste porcelain mud and damaged blanks produced by ceramic factories in the process of producing porcelain, damaged waste products that have not been calcined and glazed, semi-finished products that have been calcined and glazed in the factory, waste products due to damage or cracks, and waste products from construction Waste building ceramics, waste sanitary ceramics and other places where ceramics are applied on the construction site, as well as waste ceramic fragments a...
