A tharollo Concrete

Kajeno, ho se ho hlokahala thepa, hore na khoebo kapa poraefete, e ntseng e eketseha letsatsi le letsatsi. Le ka lebaka leo e ntseng e eketseha litlhoko tsa ka thepa ea ho haha, palo ea tse akarelletsang ho hlakileng, ditharollo hahiloeng ka konkreite, additives fapaneng ka konkreite, mixes omileng, 'me, ea e le hantle, tharollo.

Kahoo, ka tharollo majoe Lejoe ka fana ka oxyphobe solidity clinker kapa majoe bakeng sa rala. Polymer-na le mohaho ditharollo na ka mabapi bona mona ke metsoako: metsi (ka go tlhaolega e tlhotliloeng), samente (samente, samente kapa kalaka) le aggregate (lehlabathe 'me hangata gravelite). Ka tloaelo ho ka metsoako joalo (bakeng sa majoe) palo ea kalaka le lehlabathe la 1: 3 kapa 1: 4. motsoako ona o bitsoa lihahi seretse sehlopha sa pele (RG Ke). Ha mona ho motsoako (mohlala, bophahamo ba modumo dilitara tse 80), eketsa e spades maloa samente, tabeng eo fumana bobeli motsoako seretse lihlopha - WG II. Ho haha mehaho e ka microcyteme kapa makalana sebediswa samente-lehlabathe motsoako, e leng e sebelisoa ka libaka kaho ba atisa ho ba bang, 'me palo ea karolo ea metsoako e joalo, e mong ya ka yuniti ya lehlabathe: diyuniti tse tharo cementitious elements kapa e' ngoe ea lehlabathe: samente likarolo tse tšeletseng.

E boetse e atisa ho sebelisoa samente. O entsoeng ka unit trust e mong oa kalaka le lehlabathe likarolo tse tharo - e 's ho sebedisa kantle. E le karolo ea mosebetsi oa ka hare, e Correlation tsa dikarolo tse fapaneng tse 'maloa - nngwe ya ka yuniti ya kalaka ho likarolo tse hlano tsa lehlabathe. Samente samente motsoako ke seng ka tlase ratoa ho feta samente le lehlabathe ho makalana ka, 'me e na le ea ho hlophisoa tsena tse latelang: palo ea lehlabathe le samente - 1: 3. Hona joale e leng tse fapa-fapaneng ka bophara ho sebelisoe sebelisitsoe ka slurry samente e le hore ho ntlafatsa thepa mechine le 'meleng. Le litumeliso gypsum ka elements tlamang, ho tsitsipanyang crystallization thulaganyou e ka boeona e, ka ntle additives efe kapa efe.

Ha u tšoara ka cubage motsoako eketseha, hobane ho qoba sena, eketsa ka lehlabathe hanyane - karolo e 'ngoe ho likarolo tse peli tsa gypsum. From karo-karolelano pakeng tsa chelete ea binder le filler mafura hlaheletseng, 'me tloaelehileng tšesaane seretse metsoako. Tse mafura - motsoako tenyetsehang, empa etsa shrinkage khōlō nakong phekola, 'me haeba e sebelisoa le e tenya - koahetsoeng ka mapetsong. Lean na le palo e fokolang ea elements binder, 'me, Ka lehlakoreng le leng, u se fe shrinkage nyenyane haholo, e haholo-holo a ananela ha tsamaisang baeti.

Ha o batla ho fana ka ya hao lula le tatso e ikhethang, ebe ba khaotse ho khetho ea hao ka 'mala majoe seretse. Ka ho khetheha, ba khethile ho tšoanang le tobane le lintho tse bonahalang majoe motsoako etsa ho ka khoneha ho etsa seams patehileng. Seretse - e ntle lijo-thollo motsoako, e neng e ka ho feletseng vymeryat, 'me e na le e lintho tse bonahalang inorganic, e nyenyane ea metsi le dikotwana tse nyenyane tsa filler. E sebediswa bakeng sa ae kgabisa mesebetsi hare le ka ntle, empa le bakeng sa rala setene le lejoe mabota. Ho na le nomoro ya ka mefuta e mengata ea ditharollo: a thibela metsi - motsoako oa samente, eo ho eona eketsa Ceresit, ferric chloride le sodium aluminate; Ceresit - motsoako oa mmala tšoeu, e leng e fumana ka lebaka la kopantseng amyl acid e, kalaka, 'me ammonia; majoe - motsoako oa samente le kalaka kapa samente le letsopa; Samente - e akarelletsa pulverized lehlabathe bakeng sa ho bitiela mabota ka ho phethahetseng le boreleli; samente - motsoako oa samente, lehlabathe le metsi. Ho itšetlehile ka mofuta oa tharollo karo-karolelano ea likarolo tsena constituent ka 'na ba e fapaneng. Hona joale baetsi rekisa itokiselitse entsoeng motsoako oa mebala e fapaneng e hasana ka mekotla ea 10, 15, 25 le 1000 lik'hilograma. Mebala-bala majoe ditharollo na palo ya menyetla fetang ka konkreiti ba tloaelehileng:

1) lokolohile ho khetha mebala ka; 2) solidifies nakong maloa lihora; 3) ka theko e batlang e tlaase.
