The invention relates to the construction, namely the reconstruction and restoration of old buildings and structures, specifically to means and methods for flush cut-off waterproofing to protect the walls from exposure to soil moisture.
One of the serious problems encountered in the capital repair of buildings and structures, in particular historical interest is the high moisture content in building constructions.
A layer of horizontal waterproofing laid during the construction of building walls, over time destroyed, ceasing to perform its functions. Soil moisture penetrates deep into the building structures and rises due to capillary forces on the clutch all the above to a height of several floors.
Described water compositions and method for flush cut-off waterproofing. (Patent RU №2206675, C2 7 EV 1/62; SV 41/00).
The compounds are organosilicon compounds of the type:
where R; R1; R2- inorganic compounds, mainly methyl group.
This hydrophobic compounds with the disadvantage of low mobility in systems of capillaries inorganic building structures, the walls of which by their chemical nature are hydrophilic. The method consists of proburivaya in which the Lada two rows of holes, fill the top row organosilicon compound, lower - peschanozerskii solution introduction in the filled holes of the electrodes. Providing directional movement water-repellent composition due to the electrical field.
A similar method using electric field complicates and increases the cost of repairs. The closest to this invention to the technical essence is hydrophilic composition and method including liquid sodium glass and Supplement; method differs in that the composition is introduced into the material by immersion in a complex solution and maintained therein without pressure or pressure within 10-30 minutes (USSR Author's certificate No. 535259, CL SW 41/22, 1976).
Disadvantage: high viscosity composition, low penetration, the inefficiency of the method.
Also known composition for impregnation, including kationaktivnaya surfactant is disodium salt ethylendiaminetetraacetic acid (Trilon B) and Supplement.
The decision to grant a patent on the invention under the application №2006105993/04(00648 8). The composition for impregnation of building products, IPC SW 41/62 (2006.01), SW 41/68 (2006.01), 06 March 2007. The composition does not contain silicates, and not effective enough to shut waterproofing.
The purpose of the invention: reduced viscosity, increased permeability, improved performance of atsec the second waterproofing to protect the walls from exposure to soil moisture.
This is achieved by the fact that the composition comprising water glass and a Supplement that contains as water glass, potassium silicate, as an additive - kationaktivnaya surfactant - ethylendiaminetetraacetic acid (Trilon B) in the following ratio of components:
|Potassium liquid glass||a 99.6 to 99.9|
|Trilon B||of 0.1-0.4|
The recommended way is that the composition is served in the drilled masonry hole (holes), characterized in that it is served in conjunction with periodic drying in intermittent: - submission-drying-serving.
As an example, were used: potassium liquid glass, supplied by the German firm Cerezit, and domestic - in accordance with GOST 18958-73.
The density of liquid glass was installed in this and in another case 1,178/see the Amount of solid phase according to derivatographic in imported glass - 24%, in the domestic -19,2%.
The chemical composition of the solid phase, a certain method Icpspectroscopy, the following (wt.%):
Imported glass: SiO218,35: TiO20,004: Al2About3of 0.02; Fe2About30,01; MnO 0,001; CaO 0,001; MgO 0,001; Na2O 0,12; K2O 6,37; P2O50,005.
Domestic glass: SiO216,10; TiO; 0,01; Al2O3of 0.08; Fe2About30,02; MnO 0,01; CaO 0,01; 0,01 Mg; Na2O 0,62; K2About 6,90; P2O50,03.
Domestic glass, as can be seen, more contaminated with impurities, mainly sodium oxide, which affects the viscosity and filterability through the impregnated material. A smaller concentration of SiO2affects the effect of narrowing and blocking capillaries. It is important to limit the content of sodium oxide.
Trilon B correspond to GOST 10652-73.
Can be used commercially available potassium silicate in accordance with GOST 18958-73 a density of 1.1 to 1.2 g/cm3. Experimentally was installed desirable from the point of view of hydrodynamics impregnation density of the composition - 1,178 g/cm3.
Below 1,1 - reduces the effectiveness of clogged pores.
Above 1,2 - deteriorating hydrodynamics impregnation capillary pore space.
Featured modularity liquid glass 2,33-2,88.
Modularity reduces below bridging ability of silica gel. Above impairs the solubility of potassium silicate.
Experimental data on the viscosity of the compositions, the filtration coefficient in brick and lime mortar are shown in table 1.
|Table No. 1|
|The composition for injection, %||The viscosity of 3-4 sec||Coefficie the t filter in the clutch, cm/sec|
|The import. CGS||Otechestvo. CGS||The import. CGS||Otechestvo. CGS|
|1. Sodium silicate, additive (A.S. No. 535259)||14|
|IS 100 Trilon B 0||12||0,8·10-3||0,5·10-3||0,25·10-4||0,2·10-4|
|SKIS 99,9 Trilon B 0,1||11||1,9·10-3||1,6·10-3||2,2·10-4||2·10-4|
|IS 99,6 Trilon B 0,4||10||1,9·10-3||1,8·10-3||2,3·10-4||2,3·10-4|
|IS 99 Trilon B 1||10||1,9·10-3||1,8·10-3||2,3·10-4||2,3·10-4|
As you can see, the filtration rate of the composition of the mortar is higher than in the brick. Imported glass with a lower content of K2O is preferable. The proposed composition comprising potassium liquid glass and additive - ethylendiaminetetraacetic to the slot in the specified quantities (formulations 4 and 5) has a low viscosity, a significant coefficient filter has a high penetrating power.
The additive is well combined with the liquid glass, it does not cause coagulation; has a blocking property against parietal cations CA2+and Mg2+by linking their complex connection; thereby promotes the penetration of liquid glass and silica gel in smaller pores, capillaries, micro-cracks. Data on humidity construction material at different levels of the wall at different times after treatment of masonry (feature shutoff waterproofing) are presented in table 2.
Injectible composition is introduced into the clutch portions for 5-6 innings in duration innings 0.5 hour. After each drying gets a break, drying was carried out using teploelektronagrevatel (heating Elements).
Intermittent circuit - flow-warm-up - allows you to expand the area of the dried material, vaporous moisture can escape from the clutches through the drilled holes. The temperature of the masonry near the heater was 100 degrees or more.
|Table No. 2|
|The composition for injection, %||To make above ground level, m||Humidity brick masonry, %|
|Without treatment in 3 days||After injection of the composition at ground level|
|After 3 days||After 3 months||After 6 months|
The most intense moisture sucked raw samples of the brick.
Raw samples for 72 hours pull moisture up to 15-20%. Processed for the time of 3-10%.
Most high performance cut-off waterproofing are the compounds 2 and 3. Compounds 1 and 4 the worst characteristics. Was performed the experiment on the way A.S. 539259, i.e. by immersing the material in a comprehensive solution. The effect of the cut-off waterproofing has not been detected. Thus, we recommended a new composition and method, which consists in applying the composition in drilled boreholes and periodic drying in intermittent: - submission-drying-filing-that allows you to provide a flush cut-off waterproofing.
An example implementation drying: the circuit "feed-drying-submission" - 5 cycles, each cycle drying 1 hour at a temperature of 100 degrees Celsius.
To form a continuous treatment area due to the filling composition of the fine pores of the masonry, freed from moisture during the previous drying.
The composition and method is useful when renovating older buildings to stop capillary water transport in brick and stone masonry, precast structures by creating a wall of hydrophobic effect and narrowing or overlap capillaries. Possible blockage of the composition of the capillaries and cracks opening up to 0.5-1 mm, with environmentally safe. The effect persists in the case of further education secondary capillary system.
The main stages of the production of intramural guide is isolatie are: the breakdown of holes, drilling, drying of masonry with the use of electric heaters. Installation of injectors and install the feed composition, the preparation of the recommended composition, flow in a tub, periodic drying, removing the injectors, transfer, install it on the new casting section, complete.
Elements of the technology are as follows.
The surface of brick masonry, mortar, gypsum or limestone blocks, etc. to clean from dust, dirt, oil, laitance, efflorescence, etc. from any foreign substances.
- To drill unstressed way hole in the wall on the perimeter near the Foundation with a diameter of 20-30 mm at a distance of 150-200 mm at an angle of 30-45° horizontal 3/4 the thickness of the wall. Debris and dust to remove.
- To prepare a recommended composition by mixing potassium liquid glass with Trilon B in the ratio indicated.
- To fill the holes line up. To give exposure to penetration by 1/2 length to the next hole. The application of pressure.
- Perform periodic process: - submission - drying - serving.
- Holes to close up, to give exposure to seminolecounty wall.
to track the production of works for the regularity of solutions in each hole, creating a continuous treated layer. The quality of processing is determined by the drying of the masonry above the treatment area within 0.5-1 year.
When is the change of the composition and method for flush cut-off waterproofing eliminates other well-known technologies waterproofing: kerf walls, the ventilation galleries, warming plates, construction of drainage around buildings walls. Masonry walls retains its strength, the components are cheap, the technology is available, work can be done in embossed conditions without the resettlement of residents.
