Description

Brick made of mud
Technical field
Brick made of mud of the present invention is a kind of novel materials for wall, relates to material of construction.
Background technology
The area, Shanghai is positioned at the forward position, Yangtze River Delta, faces the East Sea, leans against Plain, southern Jiangsu and Hangjiahu Plain, and north relates to Hangzhou Wan according to the Changjiang river, south, except that the low mound of west and south minority, all the other physical features are smooth, and most of regional shallow soil is more typical hemipelagic sediment, also common name " Shanghai soft soil ".Shanghai soft soil has the common characteristic of general weak soil, that is: high-moisture, maximum nearly 70%; Macrovoid ratio, maximum above 1.6; High-compressibility, compression factor reaches 1.5Mpa; Low strength.The main composition soil layer of Shanghai soft soil is silt clay, mild clay, wherein accompanies silty sand matter thin layer.On such weak soil base, build highway, factory, warehouse, stockyard and various big and small buildings all need to carry out earlier foundation stabilization and could satisfy intensity, distortion and the stability requirement of engineering to ground.The most reliable way of silt clay layer that extensively distributes for Shanghai area and big and small creek, the sludge treatment in the dark pool is to change the bed course of filling out other materials after the desilting.Just produce the huge mud earthwork in the desilting engineering, improved construction costs, polluted environment.In order to protect farmland, save energy, the Ministry of Construction, territory management board send the documents, from day in April, 2000 the urban house building forbid re-using solid clay brick, from January, 2003, forbid that Bricks and Tiles Plant's regeneration produces clay brick.Just, developed novel wall material brick made of mud technology based on above-mentioned 2 points.
Summary of the invention
The objective of the invention is to: a kind of varying strength requirement of satisfying is provided, and the brick made of mud made from mud.
The object of the invention can be achieved through the following technical solutions: be main raw material with mud, being aided with aggregate materials such as solidifying agent, building waste, refuse incineration slag is spike, add the properties-correcting agent that multiple chemical industry and natural matter constitute, the block body of wall type material that mud regeneration structure properties is stable, nontoxic, harmless.According to requirement of strength, the proportioning of solidifying agent and mud is different.
Wherein, solidifying agent is mainly selected low-cost ore deposit raw material light-burning magnesium powder and halogen sheet or halogen powder for use, and not only associativity is good, and low price, production technique is simple and easy to do, realized low-cost, handle the new way of mud on a large scale.
It is the physical strength height that the solidifying agent of brick made of mud technology requires, and wear resistance is good, and water resistance is strong.Solidifying agent adds several inorganic water-proof agents and organic waterproof agent, sterilant etc., makes brick made of mud have very high resistance to compression, folding strength and better waterproof, wear resistance.
The treatment process of brick made of mud technology: the brick made of mud technology is that creek, lake, beach mud are handled the environmental protection building material that modification forms through science.
Shown in the brick made of mud technical process accompanying drawing, mud, solidifying agent, aggregate are mixed, make the mud compound, moulding, maintenance, brick made of mud moulding.
Each weight percentage is in the brick made of mud: mud 35~50%, solidifying agent 15~35%, aggregate 50~15%.Wherein, solidifying agent is made up of magnesia unslacked, halogen sheet or halogen powder, water and adjustment agent, and the weight percentage of this solidifying agent is: magnesia unslacked 52~58%; Halogen sheet or halogen powder 20~25%; Water 20~25%; Adjust agent 0.1~0.5%.
The brick made of mud manufacturing process is: the water of solidifying agent weight part 20~25% is dissolved to the solution that degree Beaume is 23~25 degree with 20~30% halogen sheets or halogen powder, add 0.1~0.5% adjustment agent then, again deployed solution is added to stir in the magnesia unslacked and makes solidifying agent, in mud, add the solidifying agent mixing and stirring, mix an amount of aggregate at last and make the brick made of mud compound, its composition by weight percentage composition is mud 35~50%, solidifying agent 15~35%, aggregate 50~15%.
With the water of solidifying agent weight part 20~25% 20~30% halogen sheets or halogen powder are dissolved to the solution that degree Beaume is 23~29 degree, add 0.1~0.5% adjustment agent then and more deployed solution is added to stir in the magnesia unslacked and makes solidifying agent.
Wherein, the MgO content in the light-burning magnesium powder be 70~90%, the MgCl in halogen sheet or the halogen powder 2Content is 42~46%.The adjustment agent is that a kind of in ferrous sulfate, copper sulfate, sal epsom, potassium permanganate, urea-formaldehyde resin, ammonium chloride, hydrochloric acid, phosphoric acid, the silicone emulsion or several combine.
This patent is cured as the road building materials with sludge treatment, recycling, becomes Fei Weibao.Its superiority is: provide a brand-new approach for handling mud on a large scale, can be fast effectively, low-cost processes is silt harmless, resource utilization, and solved the secondary pollution problem; For material of construction provides a novel environment friendly material that cheaply, need not destroy natural resources; Mud is stepped in the benign cycle of Sustainable development.So the present invention can have a tremendous social and economic benefits.
