Abstract
The invention discloses a tail slag fired perforated brick and a preparation method thereof, belonging to the technical field of perforated brick preparation method. The tail slag fired perforated brick is prepared by taking iron ore tail slag, coal ash, clay and water as raw materials, wherein the addition of the water is 10-20% of the total weight of the iron ore tail slag, the coal ash and the clay the contents of which are respectively 70-85% by weight, 8-15% by weight and 5-18% by weight. The perforated brick produced by adopting the method has the advantages of high compression strength and good durability.
Description
Technical field
The present invention discloses a kind of mine tailings sintered perforated brick and method of manufacture thereof, belongs to perforated brick preparing method's technical field.
Background technology
Perforated brick mainly is applicable to the weight bearing area of brick mix structure, is another materials for wall new variety after common and lightweight small size hollow concrete blocks.Perforated brick has that production energy consumption is low, sharp useless, the easy construction of joint soil and body is light, intensity is high, high insulating effect, durable, characteristics such as shrinkage strain is little, outward appearance is regular, is a kind of ideal material of alternative sintered clay brick.Along with construction quality require increasingly high, the ultimate compression strength of existing perforated brick can not satisfy the demand in market.
Summary of the invention
The purpose of this invention is to provide a kind of mine tailings sintered perforated brick and method of manufacture thereof with ultimate compression strength height, good endurance.
For achieving the above object, the technical scheme that the present invention adopted is:
A kind of mine tailings sintered perforated brick; With tailings of iron ore, flyash, clay, water is that raw material is processed; Wherein the add-on of water is the 10-20% of tailings of iron ore, flyash, clay summation weight, and the weight percent between tailings of iron ore, flyash, the clay is respectively 70-85%, 8-15%, 5-18%.
As the further setting of such scheme, the weight percent between said tailings of iron ore, flyash, the clay is respectively 75%, 15%, 10%.
The add-on of said water is 18% of tailings of iron ore, flyash, a clay summation weight.
A kind of method of manufacture of mine tailings sintered perforated brick comprises the steps:
(1) select for use the thickness hammer mill with tailings of iron ore and clay pulverize;
(2) with after carrying out mixing and stirring in tailings of iron ore, flyash, the clay input stirrer, add entry, continue to be stirred to evenly, obtain mixture;
(3) mixture being sent into vacuum extruder carries out extrusion molding and obtains adobe;
(4) sintering, cooling.
Said vacuum extruder is the two-stage vacuum brick extruding machine, and extrusion pressure reaches 3.0Mpa.
Through the perforated brick that the present invention produces, has the advantage of ultimate compression strength height, good endurance.
Porous brick performance of the present invention: product unit weight≤1000kg/M
2, 240mm thick wall body Coefficient K≤1.5W/ M
2.K, compression strength>=5.0Mpa, sound insulation>=45dB.
