Description

A kind of geopolymer grouting material
Technical field
The invention belongs to inorganic composite materials technical field, it is related to a kind of geopolymer grouting material and preparation method thereof.
Background technology
Geo-polymer is that geopolymer is by activated aluminosilicate material（Metakaolin, clay, slag, flyash, silicon Ash etc.）With highly basic or a class novel aluminum silicate inorganic Binder Materials of highly basic silicate solutions reaction generation.France in 1978 Famous scientist Davidovits is first geo-polymer this material designation and proposes the reaction machine of geo-polymer Reason.Geo-polymer extensively should due to having the advantages that high-early-strength, corrosion resistance, environmental protection, high temperature resistant, good endurance For fields such as construction material, traffic repairing, heavy metal ion adsorbed, nuclear waste disposals.In recent years, due to strength cement-based grouting material With chemical grouting material high cost, corrosion-resistant undesirable with flushing resistance, geo-polymer starts to apply in treatment of soft foundation, tunnel The aspects such as slip casting, pre-stressed bridge grouting, measures of cracks on concrete pavement reparation and plat-bottom escape treatment.But current geopolymer is filled Also there are following some deficiencies in slurry, limit application of the geo-polymer in grouting material field.
The content of the invention
In view of above-mentioned weak point, it is an object of the invention to provide a kind of high-early-strength, good fluidity, impervious corrosion resistant, Setting time short geopolymer grouting material applied widely.
In order to achieve the above object, present invention employs following technical scheme：
A kind of geopolymer grouting material is made up of the raw material of following weight portion：Stone flour 20-40 weight portions, flyash 30-45 parts, SILICA FUME 10-25 parts, slag powders 25-35 parts, alkali-activator 5-10 parts, NaOH 5-10 parts, sugar calcium 0.5-1 parts, can divide again Dissipate 3-5 parts of latex powder, polycarboxylate water-reducer 1-3 parts, sodium alkyl sulfonate 1-3 parts, aluminum stearate 1-3 parts, phenolic resin 10-15 Part, N, accelerine 0.5-1 parts, methyl ethyl ketone peroxide 0.5-1, Sodium Polyacrylate 0.5-1 parts, triethanolamine 0.5-1 parts, Citric acid 0.5-1 parts.
Further, the grouting material is made up of the raw material of following weight portion：30 parts of stone flour, 40 parts of flyash, micro- silicon 15 parts of powder, 25 parts of slag powders, 10 parts of alkali-activator, 5 parts of NaOH, 1 part of sugar calcium, 4 parts of redispersable latex powder, polycarboxylic acids subtract 2 parts of aqua, 2 parts of sodium alkyl sulfonate, 2 parts of aluminum stearate, 10 parts of phenolic resin, N, 0.5 part of accelerine, peroxidating first and second 0.5 part of ketone, 1 part of Sodium Polyacrylate, 0.5 part of triethanolamine, 0.5 part of citric acid.
Further, the alkali-activator is waterglass.
Present invention also offers a kind of preparation method of grouting material, comprise the following steps：
（1）By the stone flour of formula ratio, flyash, SILICA FUME, slag powders, alkali-activator, NaOH, sugar calcium, redispersible breast Rubber powder, polycarboxylate water-reducer, sodium alkyl sulfonate, aluminum stearate, phenolic resin, DMA, methyl ethyl ketone peroxide gathers PAA, triethanolamine, citric acid is placed in mixer, is uniformly mixed, and obtains compound；
（2）By compound and water with 1：0.4~0.5 weight ratio is placed in mixer, stirring mixing, obtains geopolymer grouting Material.
The present invention can flexibly be selected according to the requirement of construction, as long as at the construction field (site), plus as appropriate water is carried out Mixing just can be prepared into geopolymer grouting material.The method is similar with cement-based grout preparation method for material, and scene only needs to add water Uniform mixing, it is simple to operate.
Beneficial effects of the present invention：
Obtained grouting material 1d intensity >=20.0MPa of the invention, fluidity≤20s, the presetting period >=25min, final setting time≤ 60min.Road quick patching, Identification Beneath Concrete Slabs grouting, treatment of soft foundation, bridge strengthening crack is widely used in repair The engineering positions such as benefit, deep layer grout curtain, foot bolt fastening.Relative to traditional strength cement-based grouting material, low cost, in corrosion resistant The durability such as erosion, Heat-resistant stable, resistance to erosion aspect is more superior.In terms of existing technologies, locally aggregated thing grouting material is deposited Stable performance it is adjustable, the scope of application is big, advantage simple to operate.
