Description

A kind of mud building waste light-weight brick exempt from baking
Technical field
The present invention relates to a kind of mud building waste light-weight brick exempt from baking, specifically it is to be main raw material with sludge of sewage treatment plants powder and building waste, utilizes chemical reaction, with the light-weight brick exempt from baking of mechanical vibration extrusion molding, belongs to brick-making technology.
Background technology
Sludge of sewage treatment plants and building waste all are to adopt burying method to handle at present, reduce environmental pollution, but along with rapid increase is made in the fast development and the old housing reform of city-building, sewage disposal industry development speed is more and more faster, development scale is increasing, and mud and building waste generation are accumulated year by year and increased, and not only needs to take a large amount of land resources, also can cause secondary pollution, also cause the waste of resource.
Summary of the invention
It is the light-weight brick exempt from baking that main raw material is made with sludge of sewage treatment plants and building waste that purpose of the present invention provides a kind of in order to solve above-mentioned existing problems just, thereby both having solved mud and building waste handles problems, utilize resources synthetically has reduced the pollution to environment again.
The objective of the invention is to realize by following technical proposal:
Mud building waste light-weight brick exempt from baking is characterized in that it is made by the following weight proportion raw material:
Moisture 8-10% sludge of sewage treatment plants powder 30-50 part
Construction waste powder 30-50 part
Calcium oxide 10-15 part
Calcium sulfate 3-5 part
Cement 8-10 part
Ferrous sulfate 0.5-1.0 part
Sal epsom 6-10 part
Calcium chloride 0.5-1.5 part
MNC-Al hardening accelerator 0.1-0.25 part
MNC-C frostproofer 0.2-0.5 part
Water 8-12 part.
Described construction waste powder is dismantle and useless brick newly built construction and waste residue or the concrete waste material that old housing reform is made, and removes scrap metal and pulverizes, and its particle diameter is the powder less than 15mm; Described sludge of sewage treatment plants powder be sewage after treatment moisture 80-90% mud slurry and the mixed powder of industrial residue or building waste, its consumption of industrial residue or building waste is for making the mud powder moisture at 8-10%; The particle diameter that described calcium oxide and calcium sulfate are pulverized is less than 0.2mm.
It is the main raw material of light-weight brick exempt from baking that the present invention adopts sludge of sewage treatment plants powder and building waste, be to utilize mud and building waste to contain a large amount of silicon-dioxide and aluminium sesquioxide is the good raw material of light-weight brick exempt from baking, be mixed and made into light-weight brick exempt from baking with calcium oxide, calcium sulfate, calcium chloride, cement, MNC-Al hardening accelerator, MNC-C frostproofer chemical feedstocks, do not need high-temperature roasting and vapor cure, utilize the chemical reaction can be in ambient cure, three-waste free discharge is saved the energy, the protection environment; Ferrous sulfate is a reductive agent, and sal epsom is the retention agent of ferrous sulfate, and the smell in the mud is fully decomposed, and reaches rapid deodorizing.
The manufacture method of light-weight brick exempt from baking of the present invention is with the sludge of sewage treatment plants powder, after being moist shape, construction waste powder, calcium oxide, calcium sulfate, cement, ferrous sulfate, sal epsom, calcium chloride, hardening accelerator, frostproofer and water mixing use the mechanical vibration extrusion molding, under the pressure of 25-30MPa, make light-weight brick exempt from baking, with around the spraying seasoning maintenance at normal temperatures, make product again.
Also can be made into the holllow building block of different size with raw material of the present invention.
The light-weight brick exempt from baking of producing according to the technology of the present invention, through the relevant building materials quality detection department check of national regulation, every technical indicator all reaches the construction material standard-required of national regulation.
Building material quality measuring station detected result is as follows through Shenzhen Institute of Building Research:
Light-weight brick exempt from baking detects: according to the JC525-93 standard.Specification: 240 * 115 * 53mm
A) ultimate compression strength: 10 mean value: 9.8MPa, monolithic minimum value 7.7MPa.
B) folding strength: 2.5MPa.
C) water-intake rate: 17.1%.
D) volume density is 1503kg/m 3
The detection of non-burning brick holllow building block is according to GB15229-2002, and specification is 390 * 190 * 190mm, the highest 6.2MPa of monolithic ultimate compression strength, and minimum 4.9MPa, average out to 5.6MPa, result evaluation are 5.0 grades.
Owing to take technique scheme the technology of the present invention compared with the prior art to have following advantage and effect:
A) light-weight brick exempt from baking of the present invention, because the relative density of mud and other industrial residues and building waste is littler than clay, every light-weight brick exempt from baking than the light 0.5kg of clay solid brick about, and make hollow fragment of brick, lighter more than 30% than the building block of cement sand, therefore can alleviate the deadweight of buildings and the work-ing life of prolongation high-rise building;
B) production technique is simple, and three-waste free discharge meets No. 66 literary compositions of State Council " about greatly developing novel wall material such as the energy-conservation sharp useless heat insulating of water saving that saves land " and requires spirit, and less investment, instant effect, cost are low, profitable, are suitable for the factories that do at different levels;
C) utilize mud, building waste and other industrial residues to come brickmaking to replace traditional clay solid brick, be green building material, broad application prospect is arranged;
D) comprehensive utilization for mud, building waste and other industrial residue provides good in economic efficiency technology, has both solved environmental pollution, reduces the appropriation of land amount again.
