Description
Technical field
The present invention relates to blast-furnace dust (blast-furnace fume) effectively utilize method and can be in the foundation improvement engineering of civil construction industry or the engineering that intercepts water etc. widely used ground-improving material with the modulator approach of composition, said composition and with the injection material of its formation.
Background technology
In recent years, environmental problem is subjected to extremely paying close attention to, and particularly various trials has been carried out in effective utilization of industrial by-products.Wherein, blast furnace granulated slag, flyash or silica flour etc. have been established the multiple method of effectively utilizing, and are for example used by macro-mixing back in silicate cement, have also formulated corresponding standard in JIS.
But, still have and manyly establish the industrial by-products effectively utilize method as yet, and press for the method for utilizing of establishing them in order to make up circular form society.Blast-furnace dust is exactly one of them.
The by product that blast-furnace dust is in the steel plant process to be produced is the get up powder of gained of the flue dust collecting that produces from blast furnace during with system iron.Up to the present, the method for effectively utilizing with regard to blast-furnace dust proposed as the technical scheme (referring to patent documentation 1, patent documentation 2) that is used for the adulterant of glass fiber reinforced cement complex body.But, contain basic metal in the blast furnace ash composition, so present situation is owing to worrying that alkali is difficult to be applied to concrete, wishing to find it to utilize method.
On the other hand, ground-improving material is widely used in the foundation improvement engineering and the engineering etc. that intercepts water.
Inject chemical agent when the foundation improvement engineering is meant by underground structures constructions such as the curtain grouting of strengthening at the basic foundation of large-scale exceptional structures such as the dam of soft foundation etc. or power station and tunnel, oil or LPG deposit bases and wait the engineering that improves ground.The engineering that intercepts water is meant by injecting the water burst that injection material prevents under the place that is lower than ground water table, seabed and takes place during the excavation works of the underground structure at moisture ground place, perhaps injects the engineering of ground-improving material with the watertightness that improves ground.In addition, also have the ordinary residence that the ground of drainage difference and aqueousization ground etc. locate or the foundation improvement of mansion, and the engineering that prevent ground slump of the foundation structure of upper and lower water course etc. in safeguarding etc.
Ground-improving material is widely used in these engineerings, is the material that is used for the reinforcement etc. by ground consolidation or densification being dewatered realize ground.
Below, exemplify concrete example above-mentioned ground-improving material and the engineering of using this material are described.
For example, in the lining cutting in tunnel, when construction or after the construction, produce the cavity in the lining concrete back side sometimes.If keep this cavity no matter then the slope can cause that ground surface sinks to the blank part slump.When the slope slump is violent, there is the slump of distortion or damage, particularly tunnel that lining concrete takes place; Underground water flows into the cavity and causes the lining concrete deterioration, and the deterioration concrete one side direction driveway that is caused thus falls and in the winter time owing to come problems such as leaking of endokinetic fissure portion causes that driveway freezes.
In addition, in recent years in the ever-increasing tunnel of construction volume renovation project, have and a kind ofly in the cavity at the lining concrete back side, fill injection material, realize the steady solidified backfill grouting construction method in tunnel.Wherein employed injection material is called backing filling material, generally uses cement-wilkinite in the past.But, exist mobile excessively, backing filling material unnecessarily escapes and flows at a distance, and if water burst arranged, then backing filling material flows out or dilutedly causes degradation problem under the rerum natura.
For this reason, proposed in cement and wilkinite master material, to add super absorbent resin, increased its method of viscosity and add water glass promotion solidified method (referring to patent documentation 3, patent documentation 4).
But no matter any method viscosity rises all needs the time, and super absorbent resin itself costs an arm and a leg in the method for interpolation super absorbent resin.Also there are the following problems in addition, if promptly drop into mix in the injection material from the beginning, then because the viscosity of main material increases, causes force feed apart from shortening, and the grouting position is restricted.
On the other hand, add the method for water glass because the pH of water glass be strong basicity 13 or more, thus exist operation be severely limited, from the water of cured article stripping to environment cause bear and the longterm strength of cured article under the degradation problem.
Recently, as the method that solves the existing problem of backing filling material, following technical scheme has been proposed: in cement-wilkinite or the main material of cement-coal ash (flyash), add polymkeric substance as softening agent, instantaneous by this plasticizing improves not separation property and security (referring to patent documentation 3, patent documentation 5 and patent documentation 6) in the water.
On the other hand, for the reinforcement that obtains ground or the effect that intercepts water, adopt the injection material (referring to patent documentation 7) that has used cement.But, when geology is fine sand, mud or clay, have problems such as, grouting difficulty little to the perviousness of ground.
