Description
Technical field
The present invention relates to a kind of injecting paste material, relate in particular to a kind of red mud base novel injecting paste material for grouting and reinforcings such as tunnel, roadbed, underground workss and preparation method thereof.
Background technology
Current injecting paste material mainly contains inorganic and organic two large classes, wherein mineral-type injecting paste material is mainly take cement, cement-silicate etc. as main, although these materials have the lower and consolidating strength advantages of higher of price, but because grain diameter is thicker, slurries cannot be penetrated in the microfissure of Rock And Soil, also there is time of coagulation wayward, the slurries shortcomings such as precipitation of easily emanating; Organic injecting paste material is mainly take epoxy resin, polyurethanes as main, and these material property noted are good, but consolidating strength is lower, weather resistance is poor, expensive, especially underground water source is around had to serious pollution.Therefore, need to develop and a kind ofly can meet actual requirement of engineering, economic and practical injecting paste material again.
Along with industrial expansion, produce every year a large amount of industrial residues.Red mud is the strong basicity solid waste producing in raw material production alumina process take bauxite, and every production 1t aluminum oxide, approximately produces 0.8-1.5t red mud.China is the big producing country of aluminum oxide, and annual production accounts for 1/3 of world's total amount, and at present, China's red mud comprehensive utilization ratio is only 10% left and right, and accumulative total volume of cargo in storage is up to 200,000,000 tons.Along with the increase year after year of China's aluminum oxide output and the reduction of aluminum ore grade, red mud quantity discharged, by increasing, expects 2015, and red mud accumulative total volume of cargo in storage will reach 3.5 hundred million tons.Contain alkaline red mud bulk deposition, wasted a large amount of land resources, the environmental problem producing also becomes the great restraining factors of enterprise and national sustainable development.At present, existing many correlative studys that are applied to building material industry about red mud, are applied to injecting paste material relevant report but have no.
Summary of the invention
Technological thought of the present invention is: the activity excitation mechanism conventionally with the mineral material of lateral reactivity utilizes alkaline excitation to complete, and can generate thus hydrated calcium silicate, drated calcium aluminate and the hydrated calcium aluminate sulfate with the good hydraulicity.Utilize the active A l in red mud and adulterant
2o
3and SiO
2composition, makes its compound dissolution by the alkali excitation of alkali-activator, and depolymerization reaction occurs, and and then polycondensation occurs forms the geopolymer injecting paste material of three-dimensional network gel structure with higher-strength.
The present invention proposes a kind of red mud base novel injecting paste material, it is characterized in that: it consists of: dry powder blend material, water, compound alkali-activator.Described dry powder blend material be industrial residue red mud and mineral admixture by a certain percentage combined grinding form, according to weight percentage meter, described red mud volume is 70 ~ 80%, described mineral admixture is that slag, flyash any one or both mix again, volume is 20 ~ 30%, preferably, when both mix again, slag is 2:1 with flyash quality ratio; Described water is pure water or process water; Described compound alkali-activator is that NaOH and sodium silicate are formulated, and the suitable modulus of compound alkali-activator is 1.2 ~ 1.6, and suitable volume is 8 ~ 12%.
Serous granule fineness is less, and its penetrating quality is better, and intensity is higher, and the comprehensive product performance of the present invention and the factor consideration of controlling cost, determine that injecting paste material powder body material of the present invention must pass through grinding processing, and material granule D97 is not more than 20 μ m.
The preparation method of red mud base novel injecting paste material of the present invention is: first, prepare compound alkaline excitation agent solution with sodium silicate and NaOH; Secondly,, by combined grinding proportionally after each dry powder raw material stoving, obtain the dry powder blend material that certain fineness requires; Finally, the compound alkali-activator of preparation is added in dry powder blend material, according to certain water cement ratio mixing slurries, utilize grouting pump to get final product mortar depositing construction.
The present invention is a kind of red mud base novel injecting paste material of preparing take industrial waste red mud-mineral admixture as main raw material, the first, and the present invention is not high to the grade requirement of raw material, and trade waste is rationally utilized; The second, the present invention does not need high temperature to burn till, and has reduced the energy consumption in material preparation process; The 3rd, penetrating quality of the present invention is good, consolidating strength is higher and cheap, has overcome traditional mineral-type and organic injecting paste material many shortcomings in use, has a extensive future.
Beneficial effect of the present invention:
The Industry Waste rejected material red mud that red mud base novel injecting paste material of the present invention discharges using aluminium manufacturer in formula, as major ingredient, excites the activity in raw material with basic catalyst, can obtain a kind of Novel glue by the reconstruct-polycondensation of material dissolution-monomer and gaze at pulp material.This injecting paste material has good mobility and perviousness, and every physical and chemical performance can meet the needs of Grouting engineering substantially, and has good environmental protection and energy saving benefit.
