Description
Technical field
The present invention relates to engineering materials, being specifically related to a kind of aluminosulfate cement, ferro-aluminate cement and alumina is base material, compound multiple functional admixture material make from the agent of waterproof type high-performance quick-acting gelatin for stopping leakage.
Background technology
In construction work, hydro project, public works, often inconsiderate because of structure design, select the seepage that water-proof material is improper, construction quality is poor, uneven settlement of foundation causes construction of structures for use.Owing to when design and construction, do not take into full account the impermeability of concrete material and the brittle cracking of concrete structure, the seepage disease of various degrees such as many large-sized concrete buildingss, concrete diaphragm wall, vault, tunnel, had a strong impact on its functions of use, influence the normal use and the life-span of structures, must carry out leakage blocking and seepage-proofing and handle.
Current, and the difficulty of repairing for these works is very big.Common way has following two kinds:
1) with admixture the sand-cement slurry of water reducer, water-resisting agent and/or micro-expanding agent etc. wipe one's face;
2) brushing polyurethane water-proof paint, silicon rubber waterproof coating or organosilicon etc. on metope.
These two kinds of methods are pre-treatment of taking before engineering delivery, can improve the anti-leakage of concrete body to a certain extent.But, the seepage phenomenon often occurs in the engineering of having paid and having used, at this moment because hydraulic pressure is bigger, if adopt first method, because the adhesiveproperties of conventional cement mortar and basic unit is relatively poor and time of coagulation is long, before setting up intensity, just washed away its setting and harden usually by pressure water; If the employing second method, these waterproof paints all are solvent type on the one hand, can't combine with moist metope, and on the other hand, Bao coating also is difficult to the effect of renitency water like this.So these two kinds of usual methods all can not effectively solve the sealing leak stopping problem of the concrete structure that seepage takes place.
At present the patching materials on the domestic market mainly is divided into following a few class: the first kind is cement-inorganic coagulant class, and this class material is base-material with the Portland cement, adds a certain proportion of component with fixed attention soon, as water glass etc.Because it solidifies soon, often mix and stir inhomogeneous promptly gathering together and use, and the cement contraction is big, periphery usually seeps water.And material and the old substrate shortage of concrete cohesive force, easy and substrate breaks away from, and causes the leak stopping failure at last.Water glass has stronger corrosive nature to skin in addition, and skin ambustion brings difficulty to constructing operation easily.Second class is cement-organic setting accelerator class, this class material is base-material with the Portland cement, add patching materialss such as a certain proportion of organic solution, synthetic resin solution and water soluble resin, the advantage of this class material is that time of coagulation is fast, but cost an arm and a leg, and the performance less stable, poor durability, not acid-alkali-corrosive-resisting.The 3rd class is synthetic patching materials class, and this class material is base-material with the Portland cement, adds the commercialization patching materials that extraordinary inorganic water-proof masterbatch etc. mixes.But this class material often time of coagulation slow partially, only being applicable to that big area humidity, submerged wipe one's face to mend oozes, and is not suitable for handling the seepage of water burst and ejection.The 4th class is to be the material for quickly stopping leakage of main component with special cement fluoroaluminate cement and aluminosulfate cement, and this class material can condense in several minutes, and can produce higher hour intensity.But use fluoroaluminate cement and aluminosulfate cement material for quickly stopping leakage merely as main component, though its deficiency is to condense in several minutes, but early strength is not high enough, though compare with general cement, hour strength ratio is higher, the ultimate compression strength of general 6h can reach about 10.0MPa, but, the 1h ultimate compression strength that does not also reach the building material industry standard requirement far away is not less than 4.5MPa, and folding strength is not less than the technical requirements of 1.5MPa, is not enough to play the effect of leakage plugging under water.Secondly, adhesiveproperties does not reach the standard-required that 7d is not less than 1.2MPa especially, and is poor with the bonding properties on outmoded surface, is not suitable for the repairing of existing surface seep.In addition, consider the measure of the water resistance of raising material, for example improve the expansion character of material, to reduce fissured generation.
From these material for quickly stopping leakage in the market, the part material has the shortcoming of later stage contraction, and the expansion sources that mostly adopts swelling agent to shrink by way of compensation in case expansive agent dosage control is improper, will produce untoward reaction, influences the weather resistance of buildings; In addition, the water resistance of these patching materialss is all not obvious.Therefore, from the demand of waterproofing work, develop have water-swellable, the material for quickly stopping leakage of permanent waterproof is significant.
