Abstract
The present invention discloses an environmental protection brick and a preparation method thereof, wherein the used raw materials at least comprise, by weight, 30-65% of stone tailings, 3-15% of fly ash, 10-12% of quick lime, 10-33% of river sand, and 8-12% of water, the raw materials are mixed, the mixed raw materials are subjected to complete stirring digestion, pressing molding is performed, and high temperature and high pressure steam curing is performed to prepare the environmental protection brick. According to the present invention, the environmental protection brick has characteristics of strong compressive strength, good fracture resistance, beautiful appearance, simple process, comprehensive utilization of waste resources, raw material grading improving, low cost, and no environmental pollution.
Description
Technical field
The present invention relates to a kind of environmental protection brick and preparation method thereof, be specifically related to a kind of heavy-load bearing brick for building and preparation method thereof, belong to building material field.
Current heavy-load bearing brick for building is still based on clay brick, and its main component is clay, forms through base, roasting.Producing this brick not only needs at substantial to plough, and can discharge a large amount of obnoxious flavour in sintering procedure, as carbon monoxide, carbonic acid gas, hydrogen sulfide etc., to environment, is detrimental to health.Tradition river sand brickmaking is because aggregate is single, material fineness inadequate, and thus the grating of raw material does not reach requirement, cause product strength not high, and outward appearance is poor.
Summary of the invention
The object of the invention is to the deficiency making up above-mentioned prior art, environmental protection brick for building that a kind of ultimate compression strength is high, fold resistance good, cost is low and preparation method thereof is provided.
Realizing the technical scheme that the object of the invention adopts is: a kind of environmental protection brick, its raw materials at least comprises stone material tailings, flyash, unslaked lime, river sand and water, the per-cent that each raw material accounts for raw material gross weight is respectively: stone material tailings 30 ~ 65%, flyash 3 ~ 15%, unslaked lime 10 ~ 12%, river sand 10 ~ 33%, water 8 ~ 12%.
Present invention also offers the preparation method of above-mentioned environmental protection brick, the method is specially: select raw material, described raw material at least comprises stone material tailings, flyash, unslaked lime, river sand and water, the per-cent that each raw material accounts for raw material gross weight is respectively stone material tailings 30 ~ 65%, flyash 5 ~ 15%, unslaked lime 10 ~ 12%, river sand 10 ~ 33% and water 8 ~ 12%, fully digestion 2 ~ 6 hours is stirred by after each raw material mixing, then compression moulding, finally at 180 ~ 190 DEG C, steam press maintenance under 0.9 ~ 1.0Mpa condition, obtain environmental protection brick.
Described raw material also comprises cinder, and the per-cent that each raw material accounts for raw material gross weight is respectively stone material tailings 30 ~ 65%, flyash 3 ~ 15%, unslaked lime 10 ~ 12%, river sand 10 ~ 30%, and water 8 ~ 12%, cinder is no more than 15%.
The fineness of described stone material tailings is more than 80 orders, and fineness of pulverized-coal ash is more than 40 orders.
Described stone material tailings is grouan tailings.
The described steam press maintenance time is 8 ~ 10 hours.
Compared with prior art, the present invention has the following advantages:
1. the present invention adopts the tailings and fly ash in electric power plant that produce in grouan recovery process to improve the raw material grating of traditional river sand brickmaking, raw material after tested more than 60 orders accounts for more than 20%, and the sand grain content of below 1mm is not less than 11%, raw material grating is made more easily to reach requirement.The present invention has fully utilized waste material, has saved soil, reduces enterprise's production cost, gained environmental protection brick ultimate compression strength high (13 ~ 15MPa), fold resistance good (3.5 ~ 5MPa), good looking appearance.
2. the inventive method technique is simple, is conducive to improving product quality, without the need to roasting in production process, can not discharge obnoxious flavour, avoid environmental pollution and the harm to HUMAN HEALTH.
