Abstract
The invention discloses a concrete brick containing sludge burning ash residue, the preparation method of which comprises the following steps that: raw materials are uniformly mixed with water to be formed and to be demolded after the moisture is volatized; raw materials comprises 12 to 50 percent of cement, 0 to 30 percent of sand, 0 to 50 percent of stone, 10 to 50 percent of sludge burning ash residue and 0.1 to 0.5 percent of chemical chelating stabilizer (weight ratio); and the chemical chelating stabilizer is of complexone or organic polybasic phosphonic acid. The sludge burning ash residue which is produced in the sewage treatment plant is used for manufacturing the concrete brick, so not only the consumption of other fine aggregates is reduced without reducing the strength, but also the following processing problems of the sludge discharge reduction and sludge burning ash residue are saved, thereby saving the resource and being economical and envionrment-friendly.
Description
Technical field
The present invention relates to building materials field, disclose a kind of concrete brick, be specially a kind of concrete brick that contains sludge burning ash residue.
Background technology
Municipal sewage can produce mud through handling, and the amount of these mud is very big, difficult treatment.Handling these mud by burning, is one of main mode of following mud decrement.
In Shanghai, Shanghai has peach Pu Wastewater Treatment Plant and Shi Dongkou sewage treatment plant that mud is carried out burning disposal at present, peach Pu Wastewater Treatment Plant 6 ten thousand steres of disposing of sewage every day, produce dewatered sludge 6t/d, produce about incineration residue 2t/d every day after the sludge incineration, about 700 tons of year generation incineration residues; Shi Dongkou sewage treatment plant's 40 ten thousand steres of disposing of sewage every day produce dewatered sludge 60t/d, and produce about incineration residue 15t/d every day after the part sludge incineration, year produce about 4500 tons of incineration residues.
Sludge burning ash residue comprises slag and the ashes that produced, and slag is a yellowish-brown graininess granule, mainly comes from the auxiliary fuel coal of sludge incineration, and ashes are the pitchy powder, mainly come from the residue and the coal ash of sludge incineration.
Can predict, along with urban development, the increase of sludge of sewage treatment plants burning amount, the resource of sludge burning ash residue, harmlessness disposing mode are that one of the problem of sustainable development that influences to be solved is arranged.Utilize sludge burning ash residue to research and produce building material product, it is turned waste into wealth, meet energy-conservation, joint soil, sharp useless and the national industrial policies of environmental protection and the development strategy of sustainable development.
Studies show that, raw materials such as resulting lime-ash of sludge incineration and cement are carried out hydration reaction, the mechanical property of the concrete road pavement brick of preparation meets JC/T446-2000 country building material industry standard; The sludge incineration slag can substitute the aggregate as concrete road pavement brick, and the consumption that reduces sand class fines is to save cost.
Summary of the invention
The present invention aims to provide a kind of concrete brick that contains sludge burning ash residue.
This concrete brick that contains sludge burning ash residue, its preparation method may further comprise the steps, and raw material is added the entry mixing, and the demoulding behind the moisture evaporation is treated in moulding; Raw material comprises following components in part by weight:
Cement 12%～50%
Sand 0～30%
Stone 0～50%
Sludge burning ash residue 10%～50%
Chemistry chelate stabilizer 0.1%～0.5%;
Described chemical chelate stabilizer is complexones or organic multicomponent phosphonic acids.
The component of sludge burning ash residue comprises ashes and slag, and both mass ratioes are 2: 1～1: 2, and the mass ratio of preferred ashes and slag is 1: 1～1: 2;
Described complexones is selected from ethylenediamine tetra-acetic acid, aminotriacetic acid or ethylenediamine tetrapropionic acid; Described organic multicomponent phosphonic acids is selected from ATMP, ethylene diamine tetra methylene phosphonic acid or hexamethylene diamine tetramethyl fork phosphonic acids.
Described cement is portland cement or Composite portland cement.
This concrete brick disclosed in this invention can be used as pavior brick, is mainly used in sidewalk road surface pavement brick and other sidewalk road surface pavement brick of laying the road both sides, plays the effect of beautifying the environment and making things convenient for the pedestrian.After testing, its mechanical property meets JC/T446-2000 country building material industry standard.The sludge burning ash residue cheaply owing to mixed in concrete, its raw materials for production cost obviously reduces than conventional concrete brick.
Therefore, the sludge incineration slag can substitute the aggregate as concrete road pavement brick, and the consumption that reduces sand class fines does not influence its intensity to save cost.
Simultaneously,, make heavy metal obtain effectively control, can not cause secondary pollution environment owing to added chemical chelate stabilizer.
The present invention has utilized the sludge burning ash residue that Wastewater Treatment Plant produced, and is used to make concrete brick, both can reduce the consumption of other finess, and not reduce its intensity; Solve the subsequent treatment problem of mud reduction of discharging and sludge burning ash residue again, economized on resources economic environmental protection.
