Abstract
The invention discloses a brick-making technological method with construction waste as a raw material. The method comprises: selecting bricks and tiles, concrete, blocky and shattered lime sand from the construction waste; conducting shattering and washing to select aggregate and sand, which are stirred with cement in a dry state according to a certain proportion for 5-10 minutes, then adding an additive composed of polyvinyl alcohol, sodium sulfate, carboxymethyl cellulose sodium, calcium lignosulphonate, polyethylene glycol and zeolites, and water for stirring so as to prepare a green brick. Compared with the prior art, the invention can solve the problems of great cement consumption and high manufacturing cost in brick-making with the construction waste as the raw material.
Description
Technical field
The present invention relates to building material technical field, especially a kind of process for making of building brick.
Background technology
Quickening along with Urbanization in China, urban facilities upgrades and reconstruction of the old city town need be removed a large amount of buildingss, it is introduced the building of one square metre of every dismounting area, just can produce 0.65 cubic metre building waste, thereby the building waste amount that produces is very big, the present most employing for the treatment of process of these building wastes is cleared landfill to low-lying place and is stacked into idly, takies than large space, causes environmental pollution; On the other hand, build new engineering, need to buy a large amount of buildings again and lay bricks, if adopt the raw material of from the soil, exploiting to carry out brickmaking, certainly will will increase the weight of the consumption of land resources and cause the unnecessary misuse of transport facilities; Thereby can utilize building waste making building brick both can solve building waste land occupation and problem of environment pollution caused, and can satisfy a large amount of buildings of urban construction needs again and lay bricks, turn waste into wealth, benefit the nation and the people.The existing building waste that adopts is that the method that the raw material production building is laid bricks is: at first select brick and tile from urban architecture rubbish, concrete, block and pulverize sand-lime, then it is carried out fragmentation processing, again breaked material and cement mixing and stirring are made the brickmaking wet feed, at last wet feed is pressed into brick shape, brick drying to be formed, makes after strengthening.The building brick that adopts this scheme to produce, it is big to consume cement amount, the manufacturing cost height.
Summary of the invention
It is the method for making bricks using of raw material with the building waste that technical problem to be solved by this invention provides a kind of, and this method is compared with the existing brickmaking technology that adopts building waste and can be solved that to consume cement amount big, the problem that manufacturing cost is high.
In order to address the above problem, technical scheme of the present invention is: this is the method for making bricks using of raw material with the building waste, it is characterized in that including following steps:
The first step: from building waste, select brick and tile, concrete, bulk and the sand-lime of pulverizing;
Second step: the material of selecting is carried out Mechanical Crushing and washing, and sieve is got particle diameter＞2 millimeter, and≤5 millimeters particulate material is as aggregate; Sieve is got the particulate material of particle diameter≤2 millimeter as the sand material;
The 3rd the step: with drying aggregate, sand material and cement, additive press aggregate 40～60 weight parts, sand material 20～30 weight parts, cement is by the 3%-5% of described aggregate and sand material gross weight, mix to stir and to obtain the brickmaking siccative in 5～10 minutes, add to stir with water by 2%～4% additive of described brickmaking siccative weight then and obtain the brickmaking wet feed more than 5 minutes; The constituent of described additive and weight ratio are: specification is polyvinyl alcohol 30 weight parts, sodium sulfate 16 weight parts, sodium cellulose glycolate 3 weight parts, calcium lignin sulphonate 8 weight parts, polyoxyethylene glycol 10 weight parts, zeolite 20 weight parts of 17-88P type;
The 4th step: place the die for molding of brick press to be pressed into adobe described brickmaking wet feed;
The 5th step: described adobe obtains finished bricks through subsequent drying and reinforcement after date.
Above-mentioned is in the method for making bricks using of raw material with the building waste, scheme can be that the weight ratio of wherein used material is more specifically: described aggregate 60 weight parts, described sand material 20 weight parts, the weight of described cement is 5% of described aggregate and sand material summation, and the weight of described additive is 2% of described brickmaking siccative weight.
The weight ratio that another concrete scheme can be wherein used material is: described aggregate 40 weight parts, and described sand material 30 weight parts, the weight of described cement is 3% of described aggregate and sand material summation, the weight of described additive is 4% of described brickmaking siccative weight.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1. it is few to consume cement: because the building waste of the present invention after to fragmentation washed, the surface of aggregate and sand material obtains activation, and the adding by additive, can be so that brick producing material have just obtained high bonding strength under the very little situation of cement addition, in addition, carrying out siccative before brick producing material adds water earlier stirs, make various material of construction and the portions additive that adds obtain to mix fully, further make brick producing material under the very little situation of cement addition, just obtain high bonding strength adding the water stirring under this condition again.Therefore can obtain to consume the significantly reduced technique effect of cement amount, be that to make 390 millimeters * 190 millimeters * 190 millimeters building brick be example to raw material with the building waste, the applicant adopts existing conventional method of work, and 425 label cement consumptions are: 1500 kilograms/1000 bricks; Adopt processing method of the present invention, 425 label cement consumptions are: 400 kilograms/1000 bricks.
2. low cost of manufacture: with the building waste be raw material to make 390 millimeters * 190 millimeters * 190 millimeters building brick be example, the applicant adopts the brick making cost of existing conventional method of work to be: 1.30 yuan/1000 bricks; Adopt the brick making cost of processing method of the present invention to be: 0.85 yuan/1000 bricks.
