POSTOPEK IN NAPRAVA ZA IZDELAVO SUSPENZIJ NAJFINEJSIH CEMENTOV/NAJFINEJSIH VEZIVPROCEDURE AND DEVICE FOR THE PRODUCTION OF SUSPENSIONS OF THE finest cements / finest binders
Najfinejši cementi/najfinejša veziva se uporabljajo vedno veC v območjih popravljanja betona in geotehnike. Pri tem sluzijo cementne suspenzije, izdelane iz najfinejših cementov/najfinejših veziv za polnjenje poklin v betonu, razpok in špranj v skali kot tudi por v kamninah.The finest cements / finest binders are increasingly used in concrete and geotechnical repair areas. Cement suspensions made of the finest cements / finest binders are used to fill the gaps in concrete, cracks and slits in the rock as well as pores in the rocks.
Najfinejši cementi so zelo drobno zrnata hidravlična veziva z zvezno in ozko stopnjevitimi porazdelitvami zrn in omejitvijo najveCjega zrna. Lastnosti in uporaba najfinejših cementov je regulirana, na primer v nekem predhodnem pismenem navodilu za dela vbrizgavanja z najfinejšimi vezivi v zemlj i nah (Merkbi att fur Ei npressarbei ten mit Fei nstbi ndemittel in Lockergesteinen) (Bautechriik 70, (1993), Heft 9,The finest cements are very fine-grained hydraulic binders with continuous and narrowly graded grain distributions and the limit of the largest grain. The properties and use of the finest cements is regulated, for example, in some prior written instruction for injection works with the finest binders in the earth (Bautechriik 70, (1993), Heft 9,
Ernst & Sohn, strani 550 do 560 in ZTV-RISS 93, Verkehrsbl att--Dokument B 5237, Verkehrsbl att-Verl ag) .Ernst & Sohn, pages 550 to 560 and ZTV-RISS 93, Verkehrsbl att - Document B 5237, Verkehrsbl att-Verl ag).
Terminologija v obeh poznanih pravilnikih ni enotna. V pismenem navodilu se uporablja pojem Najfinejše vezivo in v ZTV-RISS pojem fini cement. Amerikanska literatura govori o mikrofinih portlandskih čeme n ti h (US-PS 5 106 423). V naslednjem se uporablja predvsem pojem najfinejši cement, ki se uporablja tudi v zadevnih strokovnih poročilih (Beton 1/94, strani 12 do 16, Felsbau 11, (1993), Nummer 6, Sonderabdruck, Bauingenieur 67, (1992), strani 499 do 504).The terminology in the two known policies is not uniform. In the written instruction the term finest binder is used and in ZTV-RISS the term fine cement. American literature discusses microfinance of Portland chemi n ti h (US-PS 5 106 423). In the following, the term 'finest cement' is used in particular and is also used in the relevant expert reports (Concrete 1/94, pages 12 to 16, Felsbau 11, (1993), Nummer 6, Sonderabdruck, Bauingenieur 67, (1992), pages 499 to 504).
Po predpisih pravilnikov naj bi najfinejši cement za izdelavo cementnih suspenzij imel prehod skozi sito 2 95 % pri gostoti sita 16 pm (0,016 mm) in naj bi se pripravil sAccording to the regulations, the finest cement for the manufacture of cement suspensions should pass through a sieve of 2 95% at a sieve density of 16 pm (0.016 mm) and should be prepared with
-2primernimi dodatnimi snovmi in dodatnimi sredstvi. Pojmi in vsebine pojmov sestavin dodatnih snovi in dodatnih sredstev so definirani v Zement-Merkblatt Nr. B 3, 8B0/KA 1.93/20.-2appropriate additional substances and additives. The terms and contents of the concepts of the constituents of additional substances and additional agents are defined in Zement-Merkblatt Nr. B 3, 8B0 / KA 1.93 / 20.
Posebno primernost najfinejsih cementov/najfinejSih veziv za navedene ukrepe je treba pripisati visoki finoCi pri istočasno omejenem največjem zrnu suhih veziv. Odločilna za primernost najfinejsih cementov/najfinejSih veziv pa je poleg tega porazdelitev zrn veziva v suspenziji. Tako lahko pri nezadostni obdelavi najfinej Sega cementa v vodi nastanejo oziroma ostanejo aglomerati, ki na primer izključujejo injiciranje suspenzij najfinejsih cementov v najfinejše razpoke betona.The particular suitability of the finest cements / fine binders for the above measures should be attributed to the high fineness at the same time limited maximum grain of dry binders. In addition, the distribution of the binder grains in suspension is decisive for the suitability of the finest cements / fine binders. Thus, insufficient treatment of the finest Sega cement in water may result in agglomerates forming or remaining, for example, precluding the injection of suspensions of the finest cement into the finest cracks of concrete.
Na potrebnost zadostne obdelave najfinejsih cementov /najfinejsih veziv pri izdelavi suspenzij se v zadevnih pravilnikih izrecno opozarja (ZTV-RISS, Merkblatt Feinstbindemittel - Pismeno navodilo najfinejSa veziva). V skladu z izvedbami v pismenem navodilu za najfinejSa veziva je treba za optimalno obdelavo najfinejsih veziv uporabiti izključno turbinske mešalnike ali druge mešalnike z visoko intenzivnostjo, ker je zlasti pri tehniki mesarija treba postaviti visoke zahteve. Kot primerne naprave so eksplicitno navedeni: turbinski mešalniki, centrifugalne črpalke, vijačne črpalke.The need for sufficient treatment of the finest cements / finest binders in the manufacture of suspensions is explicitly noted in the relevant regulations (ZTV-RISS, Merkblatt Feinstbindemittel - Written Instruction of the Finest Binders). According to the embodiments in the written instructions for the finest binders, only turbine blenders or other high intensity blenders should be used for optimum processing of the finest binders, since high requirements are especially required in the butchery technique. Exemplary devices are explicitly mentioned: turbine mixers, centrifugal pumps, screw pumps.
Iz Wi1ey-Interscience Publication Construction and Design of Cement Grouting je poznano, da se uporablja neko po Venturijevem principu delujoče mešalo, pri čemer se cement vsesa v vakuum in nato zmeša z vodnim curkom. Pri tem pa je navedeno, da ne pride do dobrega meSanja in je uravnavanje razmerja voda .‘cement zelo težavno, ker je treba vodo dovajati v kontinuirnem curku. Poleg tega je opisano, da taka meSala niso primerna za goste zmesi.It is known from Wi1ey-Interscience Publication Construction and Design of Cement Grouting that a Venturi-operated mixer is used, suctioning the cement into a vacuum and then mixing it with a water jet. However, it states that mixing is not good and regulating the water ratio. 'Cement is very difficult because the water must be fed in a continuous jet. In addition, such mixtures are described as not suitable for dense mixtures.
Iz EP 0 498 279'je poznana naprava za pripravo in stiskanje cementne suspenzije, ki ima območje priprave in območje stiskanja. Območje priprave in območje stiskanja sta drug z drugim povezana s povezovalnim vodom in imata vsakokrat zbiralnik, vod za krožni tok in Črpalko, ki lahko poganja cementno suspenzijo naokrog do priprave oz. stiskanja. Ta publikacija tudi navaja, da je v vodu za krožni tok območja priprave vstavljeno sito in da so zbiralniki vsakokrat obdani s hladilno napravo, skozi katero teCe hladilno sredstvo. S sitom naj bi se skepljenje prepredlo, ker se suspenzija potiska z relativno visokim tlakom skozi sito, pri čemer se v suspenziji nahajajoče se grudice razdelijo.EP 0 498 279 ' is a known device for preparing and compressing a cement slurry having a preparation area and a compression zone. The preparation area and the pressing area are connected to each other by a connecting line and each have a reservoir, a circulating flow line and a pump which can drive the cement slurry around until the preparation or. of squeezing. This publication also states that a sieve is inserted in the circuit for the circulating flow of the preparation area and that the reservoirs are each surrounded by a refrigerant through which the refrigerant flows. The sieve is supposed to prevent clamping because the suspension is pushed with relatively high pressure through the sieve, whereby the lumps in the suspension are split.

S tem postopkom v smislu izuma se lahko vsesa namesto čistega najfinejsega cementa/najfinejšega veziva tudi enako fina suha zmes iz zbiralnika 4, nameščenega pri meSalu 3. Taka suha zmes je praviloma sestavljena iz najfinejsega cementa/najfinejsega veziva in enega ali več dodatnih sredstev oziroma dodatnih snovi.By this process of the invention, the same dry fine mixture from the reservoir 4 mounted at meSal 3. Instead of pure pure cement / fine binder, such dry mixture may generally consist of the finest cement / fine binder and one or more additional agents or additional substances.
Nadaljnji predmet izuma je naprava za izpeljavo zgoraj navedenega postopka, označena s skladiščnim zbiralnikom 1 za vodo, po potrebi za dodatna sredstva za n a j f i n e j S i cement/najfinejše vezivo ali za suspenzije najfinejšega cementa/najfinejSega veziva, s transportnim vodom 7a od skladiščnega zbiralnika 1 do črpalke 2, vklopljene za skladiščnim zbiralnikom 1, z nadaljnjim transportnim vodom 7a od črpalke 2 do mešala 3, ki deluje po Venturijevem principu, kot na primer črpalka na vodni curek, pri katerem je predviden zbiralnik 4 za dodajanje najfinejsih cementov/najfinejših veziv oziroma enako finih suhih zmesi in z nadaljnjim transportnim vodom 7c od mešala 3 do skladiščnega zbiralnika 1 in z mestom za odvzem 6, povezanim s črpalko 2 preko transportnega voda 7d, pri čemer je namestitev skladiščnega zbiralnika 1, črpalke 2 in mešala 3 taka, da so ti preko transportnih vodov 7 vklopljeni ciklično drug za drugim.A further object of the invention is a device for deriving the above process, indicated by a water storage tank 1, if necessary for additional agents for the finest S i cement / finer binder or suspensions of the finest cement / finer binder, with a transport line 7a from the storage tank 1 to pumps 2 switched on behind the storage tank 1, with a further conduit 7a from the pump 2 to the Venturi-operated mixer 3, such as a water jet pump, for which a reservoir 4 is provided to add the finest cements / finest binders or the same of fine dry mixtures and with a further conveyor line 7c from mixer 3 to storage tank 1 and to a withdrawal point 6 connected to pump 2 via conveyor line 7d, the installation of storage tank 1, pump 2 and mixer 3 being such that switched on cyclically one after the other through the transmission lines 7.
V naslednjem bo izum pojasnjen podrobneje na osnovi risbe, v kateri kaže;In the following, the invention will be explained in more detail based on the drawing in which it shows;
Slika 1 neko napravo v smislu izuma za izpeljavo postopka za izdelavo suspenzij najfinejsih cementov/najfinejsih veziv.1 is a device according to the invention for carrying out a process for making suspensions of the finest cements / fine binders.
Na sliki 1 prikazana naprava za izdelavo suspenzij najfinejših cementov/najfinejših veziv obsega nek skladiščni zbiralnik 1, opremljen z mešalnikom 5, ki se lahko polni z vodo in po potrebi z dodatnimi snovmi in/ali dodatnimi sredstvi, običajnimi za najfinejše cemente/najfinejsa veziva. Transportni vodi 7a in 7b vodijo od skladiščnega zbiralnika 1 do črpalke 2 in naprej do mešala 3, ki deluje po Venturijevem principu, na primer neke črpalke na vodni curek, ki je opremljeno z zbiralnikom 4, preko katerega poteka dodajanje najfinejših cementov/najfinejših veziv oz. enako finih suhih zmesi. S podtlakom, povzročenim v meSalu 3, se najfinejsi cement/najfinejše vezivo oz. suha zmes iz zbiralnika 4 vsesa v vodo, ki teče skozi meSalo 3 s tvorbo suspenziji podobne zmesi in preko transportnega voda 7c spet transportira v skladiščni zbiralnik 1.Figure 1 shows the finest cement / finest binder slurry device comprising a storage tank 1 equipped with a mixer 5 that can be filled with water and, if necessary, with additional substances and / or additives common to the finest cements / finer binders. Transport lines 7a and 7b run from storage tank 1 to pump 2 and beyond to a Venturi-operated mixer 3, for example, a water jet pump equipped with a reservoir 4 through which the finest cements / finest binders are added, or . equally fine dry mixtures. With the subpressure induced in meSal 3, the finest cement / finer binder or. the dry mixture from the reservoir 4 is sucked into the water, which flows through the mixer 3 to form a suspension-like mixture and is again transported through the conduit 7c to the storage reservoir 1.
Suspenzija se lahko zdaj s pomočjo črpalke 2 ponovno vsaj enkrat črpa iz skladiščnega zbiralnika 1 k mešalu 3 in zmeša z nadaljnjim najfinejšim cementom/najfinejšim vezivom in se nato spet črpa v skladiščni zbiralnik 1 nazaj, pri čemer se da ta postopek tudi večkrat ponoviti, dokler se ne uravna zaželenega razmerja voda:cement in se dodatna sredstva v suspenziji optimalno porazdel I jo in obdelajo.The suspension can now be pumped back from the storage tank 1 to the mixer 3 at least once with the aid of pump 2 and mixed with further finest cement / finer binder and then pumped back into the storage tank 1 again, and may be repeated several times until does not balance the desired ratio of water: cement and the additional suspensions in the suspension are optimally distributed and treated.
Da bi dosegli optimalne pogoje strjevanja za tako izdelane suspenzije najfinejših cementov/najfinejših veziv, na primer pri polnjenju poklin ali špranj in razpok v skali, se v skladu z neko ugodno izvedbo v odvisnosti od zunanje temperature skladiščni zbiralnik I da s pomočjo naprave za segrevanje ali ohlajevanje segreti ali hladiti, tako da se da suspenzija naj finejšega cementa/najfinejšega veziva naravnati na točno optimalno temperaturno območje.In order to achieve optimum curing conditions for the finest cement / finest binder suspensions thus produced, for example when filling voids or cracks and cracks in the rock, in accordance with an advantageous embodiment, depending on the external temperature, the storage tank I is provided by means of a heating device or cooling to warm or cool so that the suspension of the finest cement / finest binder can be adjusted to the exact optimum temperature range.
Zaradi vsaj enkratnega ali večkratnega vodenja suspenzije v krožnem toku je možno, da se suha dodatna sredstva v obliki prahu najprej optimalno pripravijo v najfinejšem cementu/najfinejšem vezivu tako, da je možno reduciranje uporablje-6 nih količin dodatnih sredstev.Due to the at least one or more run of the suspension in a circular flow, it is possible that the first dry additives in powder form can first be optimally prepared in the finest cement / finer binder so that the amounts of additional agents used can be reduced.
Zaradi ločenega dovajanja vode/po potrebi dodatnih snovi/dodatnih sredstev v skladiščni zbiralnik 1 in najfinejšega cementa/najfinejšega veziva v mešalo 3 in zaradi v mešalu 3 potekajočega hitrega zmešanja sestavin, se prepreči skepljenje v suspenziji, pri Čemer se zlasti z uporabo mešala 3, ki deluje po Venturijevem principu, kot na primer s Črpalko na vodni curek, v primerjavi z mehansko delujočimi mešalniki z visokim in nizkim številom vrtljajev, prepreči dovajanje dodatne torne toplote v mešalni sistem in v zmesi tudi ne pride do nikakršnega povišanja temperature zaradi obratovanja črpalk, ker je motorni blok locen od transportnega agregata Črpalke. Na ta naCin je mogoCe pripravo suspenzij najfinejših cementov/najfinejših veziv izpeljati pri pretežno konstantni temperaturi.Separate feed of water / if necessary additional substances / additional agents into the storage tank 1 and the finest cement / finer binder into the mixer 3 and due to the rapid mixing of the ingredients in the mixer 3 prevents cumulation in suspension, in particular by using the mixer 3, operating according to the Venturi principle, such as with a water jet pump, in comparison with high-speed and low-speed mechanical mixers, prevents additional friction heat from being introduced into the mixing system and does not cause any increase in temperature due to the operation of the pumps, because the motor block is separate from the pump transport unit. In this way, the preparation of suspensions of the finest cements / finest binders can be carried out at a predominantly constant temperature.
Naprava v smislu izuma ima, poleg enostavne in hitre izdelave suspenzij brez grud z dobro obdelavo v njih vsebovanih dodatnih sredstev, še nadaljnjo prednost, da se skladiščni zbiralnik 1, na primer pri visokih temperaturah poleti lahko hladi ali segreva, Ce se suspenzija predeluje v hladni skali, da bi se zagotovila optimalna strditev v skali.The device of the invention has the further advantage, in addition to the simple and rapid production of lump-free suspensions with good treatment of the additional agents contained therein, that the storage reservoir 1, for example at high temperatures in summer, can be cooled or heated, if the suspension is processed in cold to ensure optimum solidification in the rock.
