2O)≤0.65%.This cement clinker by Wingdale, high red bauxite, anhydrite is levigate fires and form, and requires its 7 days ultimate compression strength 〉=68MPa.
Described anhydrite is a natural anhydrite, requires SO in the anhydrite
3〉=46%, one or more in also available dehydrated phosphogypsum, dihydrate gypsum, the fluorgypsum, but the SO in the gypsum
3〉=42%.Its objective is and promote C
4A
3The hydration rate of S produces microdilatancy, increases density, improves cohesive force, improves early strength, improves classification of waterproof and weather resistance.
Described Wingdale is natural fat lime stone ore stone, requires CaO 〉=52%, and its effect is to improve strength property, reduces the products production cost.
Described accelerator for hardening is the industrial lithium chloride (LiCl) or the industrial lithium carbonate (Li of purity 〉=98%
2C
2O
3), its effect is to promote patching materials rapid coagulation sclerosis, significantly improves early strength.
Described fluidizer is a polyacrylate, and its effect is to improve the incorporation degree of patching materials and plasticity-.
Described polypropylene short glass fibre specification is diameter≤60umm, length 15～19mm, and its effect is the resistance to cleavage that improves patching materials, strengthens crack resistance.
Above-mentioned sulphoaluminate cement clinker, anhydrite, Wingdale, fluidizer, accelerator for hardening combined grinding to nano level, are added the polypropylene short glass fibre again through efficiently stirring, promptly make efficient patching materials.
The technical indicator of the efficient patching materials of the present invention sees Table 1
Table 1
The performance characteristics of the efficient patching materials of the present invention:
1, fast solidifying, first final set are short at interval, and during 20 ℃ of temperature, in about 1～3 minute of presetting period, final set is after the initial set 1 minute.
2, leak stopping rapidly and efficiently can stop the certain pressure seepage in 4～6 minutes.
3, microdilatancy, impervious good, maintenance after three days in the clean slurry examination body water, waterproof under 1.5MPa hydraulic pressure.
4, strong (corrosion-resistant coefficient is greater than 1), good endurance of sulfate resistance and sea-water corrosion ability, the structure that is specially adapted to repair all kinds of chance seawater and corrodibility problem of groundwater.
5, cohesive force is strong, easily and construction surface bonding, but submersible.
6, easy and simple to handle, site operation only needs blunge to use.
7, basicity is low, and is nonpoisonous and tasteless, and safety, environmental protection do not have any harm to human body skin.
The present invention is a kind of fast solidifying, hour intensity height, hydraulic cementing materials with microdilatancy performance, can be widely used in leak stopping sealing, the repairing of engineerings such as house, municipal administration, underground, railway, water conservancy, mining industry, tunnel, pond, swimming pool, lavatory, kitchen, and engineering such as perfusion waterproofing and leakage-stopping etc., also can be used for the quick seam, leak stopping of pipeline etc.
