Abstract
The present invention discloses a production method of concrete brick by utilizing waste foundry sand. Its raw material includes hardening solidification agent, cement, waste foundry sand, furnace slag of cupola furnace and water, and its production process is identical to existent process.
Description
The invention belongs to a kind of material of construction, relate in particular to a kind of concrete brick.
At present, the starting material that adopted in the standard JC446-91 that has set up the project at home " concrete road pavement brick " standard and GB8239-1997 " normal concrete small hollow block " standard are building sand, flyash, coal gangue, boiler slag etc., adopt above-mentioned raw materials brickmaking to cause the waste of building sand resource easily, cost is higher, and dig sand in large quantities and can damage plough, people's living environment is had certain influence.
Purpose of the present invention is intended to overcome above-mentioned shortcoming, a kind of high strength is provided, reduces the wasting of resources and can eliminates the concrete brick that utilizes cast waste sand to produce that foundry waste pollutes.
For achieving the above object, solution of the present invention is: utilize foundry waste---cast waste sand, cupola slag, and add sclerosis peptizer, cement and an amount of raw materials such as water compacting and form.
Above-mentioned concrete brick is characterized in that: described sclerosis peptizer is industrial potassium alum or calcium chloride.
Above-mentioned concrete brick is characterized in that: the weight proportion of described raw material is:
Sclerosis peptizer 1-2 part cement 8-12 part
Cast waste sand 40-45 part cupola slag 40-45 part
Water 1-6 part
Production method of the present invention is: first magnetic separation, screening cast waste sand, magnetic separation, pulverizing cupola slag, to harden then and send into loading hopper after materials such as peptizer, cement, cast waste sand, cupola slag measure respectively and enter stirrer, add an amount of moisture content simultaneously, carrying out material mixes, mixed blank is delivered to storage hopper through transfer roller, the demoulding after box for feeding odd enters the hydropress extrusion forming automatically again, between maintenance, place natural curing in 24 hours after the demoulding, last piling, packing, be put into the maintenance of finished product reservoir area 28 days, and can dispatch from the factory.
The concrete technological process of production is as follows:
(magnetic separation, screening) cast waste sand, (magnetic separation, pulverizing) cupola slag, cement, sclerosis peptizer
Add the water stirring after doing stirring
------------cloth---shakes extrusion forming---------to give truck
The inspection after construction of product initial survey
------the demoulding------------piling---packing---of natural curing between maintenance in 24 hours
Maintenance product sampling observation in 28 days
---------------dispatched from the factory in the finished product reservoir area.
Compared with prior art, the present invention has following advantage:
1, the Shanxi Province is the production base of China's graphitic cast iron scatterer.Since the reform and opening-up, relied on Three Jins coal iron resources advantage, casting industry has been obtained significant progress, and has driven the leapfrogging growth of regional economy, and radiator industry becomes the tap of this area's economy.But in the time of development, also paid environmental pollution, the cost of the wasting of resources, only the big magnificent radiator of the subordinate enterprise of Zhao family's fort group company company limited discharges about 180 tons of casting waste residue, antiquated sand every day, annual about 54000 tons of the waste residue of discharging has certain influence to surrounding environment and resident.The present invention utilizes the waste of casting industry just---cupola slag, cast waste sand; add sclerosis peptizer, cement and water and produce concrete brick; like this; not only solved the pollution problem of foundry waste; protected environment again, and driven the development of foundry industry related industries, will form with the leading building materials comprehensive utilization enterprise of foundry industry; help this area's sustainable development of economy, its economic and social benefit is all considerable.
2, enforcement of the present invention can reduce the raw materials cost of existing concrete brick.
Embodiment 1: concrete road pavement brick, and its raw material and weight proportion are:
8 parts of 1 part of cement of industry potassium alum
40 parts of 40 parts of cupola slags of cast waste sand
1 part in water
Embodiment 2: concrete road pavement brick, and its raw material and weight proportion are:
12 parts of 2 parts of cement of calcium chloride
45 parts of 45 parts of cupola slags of cast waste sand
6 parts in water
Embodiment 3: concrete road pavement brick, and its raw material and weight proportion are:
10 parts of 2 parts of cement of industry potassium alum
42 parts of 42 parts of cupola slags of cast waste sand
3 parts in water
Proportioning raw materials by the foregoing description both can be made hexagonal pavior brick, also can make tetragonal pavior brick, and sexangle pavior brick demoulding applying pressure is 7-8Mpa=95kg/cm
2, square pavior brick demoulding applying pressure is 11-13Mpa=94.1kg/cm
2, can reach the standard of premium grads among the JC446-91 " concrete road pavement brick " through above-mentioned proportion scale and the prepared pavior brick of pressing force.
The normal concrete small hollow block proportioning raw materials is identical with pavior brick.Difference is to use the demoulding of the program control oscillatory type hydropress of photoelectricity, and test-results reaches GB8239-1997 " normal concrete small hollow block " standard MU3.5 level, can be used as the bearing type walling unit and uses.
Embodiment 4: color concrete brick, its bottom base adopt sclerosis peptizer, cement, cast waste sand, cupola slag and hydraulic pressure system to form, and precoat is made by white cement, pigment, sand, and be then that precoat and bottom base vibrations pressurization is promptly plastic.
Its concrete technical process is as follows:
---adding water stirs, and------bed material is given truck, and---cloth---shakes extrusion forming---for (magnetic separation, pulverizing) cupola slag, (magnetic separation, screening) antiquated sand, cement, sclerosis peptizer after dried the stirring
The inspection after construction of product initial survey the is molded---demoulding---------piling---packing---of natural curing between maintenance in 24 hours
---------dispatched from the factory in 28 days examination and test of products finished products of maintenance reservoir area.
