Abstract
The invention relates to wall materials used in construction industry, more particularly to an oil shale waste wall brick and a preparation method thereof. The method comprises the steps of: mixing brick-manufacturing raw materials in proper proportions required by the proportion scheme, adding the appropriate amount of water, uniformly stirring and then filling the stirred mixture in a brick-manufacturing mold, and obtaining the wall brick by extrusion forming or vibration forming and then wet curing, wherein the raw materials include the oil shale waste. In the above scheme, the raw materials of the wall brick further include fly ash, sand, cement, quicklime and activator. The wall brick has the advantages of using the waste as the valuable and environmental protection, and has prominent economical and social benefits.
Description
Technical field
The present invention relates to materials for wall used in the building trade, particularly oil shale waste wall body brick and preparation method thereof.
Background technology
Oil shale reserves is very abundant in the world, and stock number that it has been established that is 10,727 hundred million tons.The purposes of oil shale mainly is to refine shale oil or be directly used in combustion power generation by destructive distillation.But the content of ashes of oil shale can produce a large amount of lime-ash, i.e. oil shale waste greater than 40% during development and utilization.At the commitment of oil shale exploitation, owing to lack environmental consciousness and sustainable development idea, the processing mode of oil shale lime-ash is directly abandoned accumulation often, caused taking in a large number of serious ecological environmental pollution and soil.Until current, though extensive day by day both at home and abroad to the research and the application of oil shale waste, can guarantee that bigger utilization, the oil shale waste that has a better economic value added again utilize scheme actually rare.The main research and the application of oil shale waste are aspects such as metallic element extraction, waste gas and wastewater treatment, agricultural fertilizer, chemical products and constructional materials production at present.Owing to through high temperature action, after the organic oil material after-flame volatilization wherein, stay a large amount of micropores when oil shale waste forms, internal surface area significantly increases, active higher, can be used to produce building material products such as cement, wall body brick, concrete light aggregate, have good economic value added; Because building material industry is bigger to the use amount of oil shale waste, can solve the accumulation problem of oil shale waste effectively, simultaneously for the oil shale industrial expansion is removed the obstacles.Therefore, oil shale waste is the main direction of oil shale waste research and application in the research and the application of building material industry.At present, utilize oil shale waste to produce building material product and mainly contain (1) as the cement doping material." utilize oil shale waste and combustible gas to generate electricity and produce the method for clinker " (application number: 200710012507.9) etc. of the patent of this respect main relevant model, Xin Fuge; (2) be used to produce haydite.The patent of this respect mainly contains the Guo Li's of China University of Geosciences etc. " with haydite of oil shale waste preparation and preparation method thereof " (application number: 200610019341.9) etc.; (3) be used to produce light-weight brick.The rarely seen Jilin Province Building Materials Industry Design and Research Institute of this respect is main raw material(s) with the oil shale waste, produces and steam the report of pressing the oil shale slag brick, do not see related application.As seen, utilize oil shale waste manufacturing building material product to still need and strengthen research energetically.
Summary of the invention
Purpose of the present invention
The purpose of this invention is to provide a kind of non-autoclaved and unburned wall body brick with oil shale waste preparation and preparation method thereof.On the one hand, the oil shale slag brick that makes can replace solid clay brick fully, can save the clay resource that the mankind depend on for existence, protects farmland; On the other hand, realize twice laid, turned waste into wealth, not only alleviated the pressure of environmental protection aspect, helped human kind sustainable development again, had tangible economic benefit and social benefit.
Technical solution of the present invention
The technical solution adopted in the present invention is: with the wall body brick of oil shale waste preparation, it by match ratio scheme batching, adds suitable quantity of water with raw material, inserts brick-making mould after stirring, and wet curing is made after extrusion modling or vibration moulding, raw material packet oil scraper shale slag.In the such scheme, also comprise flyash, sand, cement, quicklime and exciting agent in its raw material.The percentage by weight of each component is in the raw material:
Oil shale waste 30.0 ~ 45.0%, flyash 5.0 ~ 10.0%, sand 18.0 ~ 30.0%, cement 20.0 ~ 35.0%, quicklime 2.0 ~ 8.0%, exciting agent 0.5 ~ 1.2%, the weight ratio (ratio of water to material) of water and other raw material gross weights is 0.18 ~ 0.25.
The described exciting agent of such scheme is a water glass.
The present invention with the method step that oil shale waste prepares non-autoclaved and unburned wall body brick is: (1) is with oil shale waste, quicklime porphyrize homogenizing; (2) weigh batching; (3) adding water is stirred to evenly; (4) insert brick-making mould pressurization extrusion modling or vibration moulding; (5) demoulding maintenance.
Technique effect:
The wall body brick structured size that the present invention makes, corner angle are clearly demarcated, the surfacing flawless, and the color and luster light gray is with dark yellow slightly, and the closely knit exquisiteness of outward appearance, every performance indications reach the standard of 15 grades of fly ash brick MU15 and Autoclaved limesand bricks.
The advantage of the inventive method is:
1, utilize oil shale waste to prepare non-autoclaved and unburned wall body brick, product has added value preferably.
2, because the chemical composition of oil shale waste mainly contains SiO
2, Al
2O
3, Fe
2O
3, CaO, MgO etc., its chemical composition and content and clay are close.Therefore, the oil shale waste instead of clay is as the raw materials for production of wall body brick, and is not only sharp useless, and joint soil.
3, owing to adopt the method for extrusion modling to make the oil shale slag brick, do not need high temperature sintering, and need not adopt the steam press maintenance method, save the energy.
4, utilize oil shale waste to prepare wall body brick, can use oil shale waste in a large number, effectively solve the accumulation problem of oil shale waste, have huge social benefit and environmental benefit.
5, the energy-conservation profit of oil shale slag brick is useless, and " turning waste into wealth " is with low cost, and to compare economic indicator good with other materials for walls (as various concrete blocks, Autoclaved limesand brick etc.), has good economic benefit.
