Description

The method of producing composite gel material from industrial residue and matrix material thereof
Technical field
The invention belongs to the energy-conserving and environment-protective field of compound material in the field of new, the trade waste that utilizes that particularly relates to material of construction is produced the method and the technology of composite gelled material.
Technical background
Industries such as building, concrete, road construction, prevention of mass concrete use cement as the building hydraulic material in a large number, at present China is the country of cement output first in the world, need to consume resources such as a large amount of lime, coal, electricity, discharge waste gas such as a large amount of nitrogen peroxide, carbonic acid gas, sulphur trioxide, in order to reduce production costs, enterprise adopt the admixture blended material as stopping composition to save cement clinker and to regulate cement mark.But to reduce cement performance is cost, as reduce intensity, bleeding is big, water requirement is high, hydration heat is high or the like.Also make the bigger cement type of admixture blended material amount have the compatibility problem with admixture.It is organically compound that the present invention adopts various trade wastes to carry out, make full use of and bring into play the synergistic effect of multiple trade waste material, thereby reduce the usage quantity of cement clinker significantly, minimizing is because of a large amount of energy that clinker burning consumed, reduce the discharging of carbon, nitrogen, reduce the material of construction cost, make the composite gelled material of development have intensity height, hydration heat low, with advantages such as admixture adaptability is good, it is a kind of high-performance composite gelled material.
Comprehensive utilization industrial waste resource is produced composite gelled material, can reduce the wasting of resources, make limited resources obtain recycle, save cost greatly, avoid blindness to the waste of resource and loss economically, have extremely-huge economic and social benefit.
Summary of the invention
At the energy consumption height of existing gelling material existence, the shortcoming and the problem of waste resource, the object of the present invention is to provide a kind of composite gelled material that utilizes the trade waste resource to produce the method for composite gelled material and utilize this method to produce.
Technical scheme of the present invention is as follows:
Utilize the trade waste resource to produce the method for composite gelled material, it is characterized in that:
A kind of powdery product that various active blended materials such as the limestone tailing of the coal gangue that (1) composite gelled material is the sugared filter mud that produces in the blast furnace slag that utilizes various waste resources in the industrial production such as Iron and Steel Production to produce, the Closed Circulation in Sugar Production, coal production produces, the flyash that power plant produces, paper waste that the paper mill produces, mining, slag, carbide slag, lithium slag, cement clinker, toughener are prepared from through the modification grinding.
(2) the composite gelled material main chemical compositions is SiO2, Al2O3, Fe2O3 and CaO, has super-active;
(3) key of composite gelled material is that various trade waste resources are brought into play synergistic effect jointly, and so-called " synergistic effect " is meant the stack of the compound back of two or more trade waste components performance, the effect of promptly learning from other's strong points to offset one's weaknesses, having complementary advantages.Mainly play following three effects: the one, activating effect, it is relevant with the component and the fineness of trade waste resource.The 2nd, filler effect, it combines with the silicate minerals hydrated product, plays skeleton function.The 3rd, tightly packed effect when the particle diameter of trade waste resource is very little, can obviously improve the degree of compactness of material, improves the performance of hydraulicity structures, improves the intensity of structures.
(4) production of composite gelled material need be used the grinding machine grinding, various materials is reached can bring into play the grain composition of collaborative effectiveness, reaches various trade waste resources again and reaches and mix.Grinding process can be taked the mode of classification grinding, also can take the technology of common grinding.
(5) composite gelled material grinding process controlling index specific surface area is at 550~600m 2In/kg the scope.
(6) composite gelled material is mixed cement as adulterant, concrete or utilize in the modification gel powder cement production concrete, the contained SiO2 of these highly active composite gelled materials, Al2O3, Fe2O3 can react with the Ca (OH) 2 that C3S in the cement and C2S aquation produce, further form the hydrated calcium silicate product, be filled in the hole of cement concrete, increase substantially the density of cement concrete, simultaneously that intensity is lower Ca (OH) 2 crystal have changed into the higher hydrated calcium silicate gel of intensity, thereby cement or concrete a series of performance are significantly improved.
Described trade waste resource can be adjusted according to its chemical ingredients, can increase and decrease according to various places trade waste resource situation.
Described grinding machine can be that ball mill also can be that air swept mill, and the grinding machine specification is determined according to design output and trade waste resource fineness.
Described composite gelled material can directly mix in the cement as product, reduces cost; Described composite gelled material can be used as hydraulic cementing materials can be directly as in concrete material or the mass concrete.
Technique effect of the present invention is as follows:
The present invention by the trade waste resources that adopt multiple country such as blast furnace slag, sugared filter mud, coal gangue, flyash, paper waste, limestone tailing, slag, carbide slag, lithium slag, cement clinker, toughener and encourage to utilize as the matrix material, a kind of Powdered composite gelled material product that is prepared from through the modification grinding.
Utilize the effect of composite gelled material product of the present invention to be:
(1) can increase substantially concrete intensity, make the concrete of high-strength and high performance;
(2) be used for cement and concrete production, can reduce cement, concrete production cost;
(3) can effectively suppress the alkali-aggregate reaction of concrete etc., significantly improve concrete alkali resistant aggregate reaction performance, improve concrete weather resistance;
(4) can effectively improve concrete anti-seawater etch performance, be specially adapted to anti-seawater engineering;
(5) can significantly reduce concrete bleeding quantity, improve concrete workability;
(6) can significantly increase the density of cement concrete, improve the impermeability of cement concrete;
(7) can significantly reduce the hydration heat of cement concrete, be applicable to the preparation mass concrete.
The present invention is a large amount of trade waste resources of using in process of producing product, can be in a large number with waste as recycling, saved a large amount of national resourcess, reduced the pollution to environment of trade waste, contemporary use for cement clinker, reduce a large amount of energy consumptions and the resource consumption in the cement production process, can effectively reduce product cost, economize on resources, reached the purpose of energy-conserving and environment-protective.
