Abstract
The building material produced with industrial slag has aggregate comprising flyash 65-80 wt%, molten slag 10-20 wt% and calcium sulfate 5-15 wt%, and the aggregate is compounded with promoter, curing agent and magnesium chloride solution in certain proportion to form the building material. The building material is produced into various kinds of bearing or non-bearing hollow or solid building boards in the method similar to that of making cement board. The present invention has wide material source, environment friendship and saving in energy, and the produced board has light weight, high strength and high heat insulating effect.
Description
The present invention relates to a kind of classification number is CO4B 18/08,18/14,14/42, EO4C 2/30, the material of construction that utilizes industrial residue to make, particularly with flyash, industrial melting waste slag etc. for the hollow wall of aggregate making, brick, watt, various material of construction such as sheet material.
At present, external and internal wall material for building is mainly used vitrified brick, and interior body of wall has light heat insulation materials such as the benzene of use plate, heat preservation composite wall plate or insulation quilt, and main drawback is: 1, waste a large amount of land resourcess, waste energy; 2, cost of manufacture height, complex process; 3, constructional difficulties is owing to the difference of operation skill influences construction quality.Disclosed application number is 02109640.6, title " load-bearing and non-load bearing partition cored slab " patent application, the manufacturing technology of disclosed building hollow wall sheet material, be to make aggregate with the flyash industrial residue, wherein added 10～15% lime carbonate in the aggregate, in the actual fabrication process, drying and setting rate are slow, particularly the prefabricated speed of winter construction is slow, and intensity also is under some influence.
The objective of the invention is the defective that exists in the above-mentioned compounding process, a kind of more rational compounding process is provided, promptly utilize flyash, industrial melting waste slag etc. to make various structure materials such as inside and outside body of wall hollow plate for aggregate.
Aggregate that the present invention mainly is made up of flyash, melting waste slag and calcium sulfate and the magnesium chloride solution that adds promotor, solidifying agent are mixed with, and it is characterized in that:
A) weight proportion of aggregate:
Flyash 65～80%, melting waste slag 10～20%, calcium sulfate 5～15%, magnesium oxide 5～10%;
B) magnesium chloride solution
Magnesium chloride: water=1: 1.5～2.0 (weight)
Magnesium chloride brine: solidifying agent: promotor=100: 0.1: 0.1 (weight);
C) aggregate: magnesium chloride solution=100: 10～20 (weight).
The present invention at the aggregate weight proportion of making bearing wall, sheet material is:
Flyash 65～70%, melting waste slag 15～20%, calcium sulfate 10～15%, magnesium oxide 5～10%;
The aggregate weight proportion of making non-bearing wall body, sheet material is:
Flyash 70～80%, melting waste slag 10～15%, calcium sulfate 5～10%, magnesium oxide 5～10%.
Flyash of the present invention can replace with coal gangue subculture, melting waste slag is to smelt pig iron grain slag (to enter the expanded waste material white foam that goes out in the water when iron work goes out molten iron, contain multiple compound composition such as calcium, magnesium, silicon), smelting furnace waste residue etc., the agricultural straw of also available 1～2 centimeter length of this melting waste slag replaces.The solidifying agent that adds in the preparation magnesium chloride solution is selected methylethyl ketone peroxide for use, and promotor is selected cobalt naphthenate for use.
The present invention has following advantage:
1, utilization of waste material is beneficial to environmental protection, saves the energy;
2, owing to add gypsum in the aggregate, quickened solidification forming speed, matching with other component has increased the intensity of sheet material;
3, this hollow wall sheet material insulation, soundproof effect are good;
4, in light weight, the easy construction of plate body has reduced a large amount of mechanical means, with this compounding process can prefabricated various hollow wall panels, hollow brick, pavement brick, watt, material of construction such as road surface.
Below by embodiment the present invention is described in detail.
