Description
<p>TITLE: Sealing agent for waterproof bafflers</p>
<p>DESCRIPTION</p>
<p>The subject of the invention is a sealing agent for making waterproof bamers in the form of water suspension made of polymineral clays.</p>
<p>There is already a patent no. PL 174766 made on another sealing agent for making waterproof bamers in the form of water solution made of polymineral clays.</p>
<p>The agent is a clay and cement water solution comprising 6-15% of cement, 19 -34% of clay, or better heavy clay with a plasticity factor JL = 15-20, in a granulometric composition of which the particles < 5 pm make up at least 60%, and particles > 50 pm make up not more than 5%. The mineral composition of the clay shall include kaolinite, hydromica and quartz, while in its chemical composition the content of A1203 should be about 20-28% and the content of Si02 should be 50-60%. Its transfer capacity should equal 15-30 milligramme equivalent units on bOg of dry clay and core composition of transferable cations is represented by Ca2 > Na > > Mg2. The agent is to be dissolved to 100% with water and/or natural brine. Moreover, the patented sealing agent includes S...</p>
<p>coherent and/or gritty clay, with a plasticity factor of JL= 6 -18, in the S. ** : *. granulometriC composition of which the particles < 5 pm make up 40-80%, and I..</p>
<p>particles > 50 pm make up about 5-9%. The mineral composition of the clay includes kaolinite, hydromica, mixed layer formations, quartz and carbonates while in its chemical composition the content of A1203 is about 18-24% and the S102 content about 55-65%. Its transfer capacity equals 25-40 milligramme</p>
<p>V</p>
<p>equivalent units on bOg of dry clay and core composition of transferable cations is represented by Ca2> Na > > Mg2.</p>
<p>The available sealing agent is particularly suitable for making waterproof barriers in rock fissures and loose soil by means of the injection method for rock, and deep soil mixing for loose soil.</p>
<p>However, due to its rheological, structural and mechanical properties, the available sealing agent does not guarantee in all geological conditions the leakproofness of the waterproof barriers, made by filling with the sealing agent solution formerly made openings, fissures, ditches, excavations, and other similar, deep and narrow hollows.</p>
<p>It transpired, however, that the addition of fly-ash (flue dusts) and/or rock dust of similar granulation as filling material to the patented sealing agent in the form of a clay and cement solution, with a simultaneous modification of the solution formula, produces a very efficient sealing agent for the construction of waterproof bamers by filling formerly excavated hollows in the ground with the sealing agent solution.</p>
<p>In accordance with the invention, the reformulated sealing agent for S. .... waterproof barriers in. the form of a clay and cement suspension made of polymineral clays, is characterized by the content of 3-15% parts by weight of cement, up to 65% parts by weight of fly-ash and/or rock dust and about 30-60% :: parts by weight, and better up to 50% parts by weight, of water suspension of * clay, heavy and/or loamy.</p>
<p>The product seems to have improved parameters when clay is added with a granulometric composition in which the particles < 5 pm make up at least 60%, and the mineral composition includes kaolinite, hydromica and quartz, with a chemical composition characterized by a Al203 content of about 20-28% and Si02 at about 50-60%, a transfer capacity equal to 15-30 milligramme equivalent units on 1 OOg of dry clay, and a core composition of transferable cations represented by Ca2 > Na> K> Mg2.</p>
<p>The reformulated agent requires the addition of portland cement, or portland cement with a sulphate resistance feature, or low aluminate cement and aluminium oxide containing cement.</p>
<p>The water content in water suspension is, according to the patent description, so adjusted that, after all the ingredients have been mixed, the density of a freshly made suspension of ready to use sealing agent equals from 1.40 to 1.65 Mg/rn3, and better not less than 1.45 Mg/rn3.</p>
<p>According to the patent description, the sealing agent contains at least 5% parts by weight of cement, up to 65 % parts by weight of fly-ash and/or rock dust of similar granulation, and 30-60 % parts by weight of water suspension of clay with such a content of water that a freshly made suspension of ready to use sealing agent has a density of 1.40 -1.65 Mg/rn3. I. *.</p>
<p>: . According to the patent description, the sealing agent is cheap, easy to prepare at a construction site and easy to apply while its rheological, structural and mechanical properties enable the construction of very efficient watertight bamers. The practical tests made 28 days after the construction of filter proof barriers of the above mentioned agent proved that the axial compression of the barriers equalled at least 0.3 MPa, and the filtration factor was less than lxlO-8 -4. rn/s.</p>
<p>The invention is further described in the following practical examples of its composition and application.</p>
<p>Example I.</p>
<p>The sealing agent for waterproof bamers contains 7% parts by weight of portland cement, 52% parts by weight of fly-ash and rock dust mix, and 41% parts by weight of water suspension of loamy clay.</p>
<p>Any rock dust might be used for the preparation of the agent, provided that its granulation is similar to that of fly-ash, for instance calcareous, basaltic or dolomite dust might be used.</p>
<p>The clay which was used for the purpose had a granulometnc composition in which the particles <5 pm made up at least 60%, the mineral composition included kaolinite, hydromica and quartz, the chemical composition had the content of Al203 at about 20-28% and Si02 content at about 50-60%. Its transfer capacity was equal to 15-30 milligramme equivalent units on I OOg of dry clay, and a core composition of transferable cations was represented by Ca2> Na' > K> Mg2 The agent can be applied in a fresh water environment with low mineral content.</p>
<p>The sealing agent is to be prepared outdoors, close to the construction site of a waterproof barrier, using the following tools: -a clay mixer; a vibratory sieve for separation of small stones, sand and other particles from the clay and water suspension; -a tank for storage of the suspension; -a set of pumps and a piping system for pumping the suspension and for water supply; -a silo and a feeding device for the supply of fly-ash and, optionally, a silo with a rock dust feeder; -a silo and a feeding device for the supply of cement; -a paddle mixer; -a tank for periodic storage of the suspension of the sealing agent.</p>
<p>The preparation of the sealing agent is a two-stage process.</p>
<p>First, the basic suspension of clay with a density of 1.18 Mg/rn3 is to made.</p>
<p>To prepare the suspension, an appropnate amount of water should be poured into a clay mixer, and while the mixer is operational, an appropriate amount of clay should be added gradually. The density of the suspension should be tested from time to time, If too dense, add water to dilute until you get the desired density of the basic suspension. S... * * ***.</p>
<p>The process of preparation of the basic suspension is considered S. completed when the density parameters of the suspension are stabilised and as required.</p>
<p>*:*. In the next step the basic suspension is poured onto vibratory sieves and directed towards a storage tank. The production cycle is then repeated with a new portion of ingredients until an appropriate amount of the suspension is produced.</p>
<p>To prevent sedimentation of the stored suspension while new portions are being produced, it should periodically be pumped around in a tank -pump -tank cycle. The production of the suspension of the reformulated sealing agent is made at the second stage of the process, which takes place just before using the sealing agent at the waterproof baffler construction site.</p>
<p>To make the sealing agent itself, an appropriate amount of the basic suspension should be pumped into a paddle mixer, to which an appropriate amount of cement should added next. All substances shall be mixed for at least 5 to 10 minutes. While the ingredients are being paddled, an appropriate amount of fly-ash with an optional addition of rock dust should be added gradually. Density tests should be made from time to time to check the parameters.</p>
<p>To get the desired density of the basic suspension water should be added to dilute until the suspension achieves an appropriate density. The process of preparation of the suspension of the sealing agent Is considered completed when the density parameters of the suspension are stabilised and as required.</p>
<p>Next, the ready to use sealing agent is collected in a second tank, from :. which it is pumped directly to the waterproof baffler construction site. * a S...</p>
<p>When an appropnate amount of the sealing agent has been piped into the *5 place or there is a break in the piping process lasting more than 15 -20 minutes, *1S the pumps, piping system and the storage tank for the sealing agent should be *. S * S* * washed with water. I. S * S S S 55</p>
