I-cement mortar for screed floor: isilinganiso

Idivayisi ye-screed phansi ingabhekwa njengenye yezinto ezibaluleke kakhulu ekukhwaleni izakhiwo.

Kubalulekile ukugcina inani

Kuphakathi kokulungiswa kwesisombululo ukuthi inani elikhulu lamaphutha livunyelwe. Futhi ngokuvamile kaningi akuxhunyiwe nokulungiswa okungalungile kwesisombululo, kodwa ngokuhluleka ukuhambisana nezilinganiso ezidingekayo zesihlabathi nesamente, yilokho okuholela emphumela, okuyinto inkosi engayilindele ukuyibona. Kubalulekile ukukhumbula ukuthi ikhwalithi yokugqoka yokugcina ixhomeke ekubaleni kwezithako.

Ukwakhiwa kwesikhumba sokukhishwa

Uma uthatha isinqumo sokulungisa udoti olwenziwe phansi, inani kufanele lifundwe kusengaphambili. Ingxube iqukethe ishlabathi, i-fibre, i-plasticizer, nesamente. Isithako sokuqala kufanele sieve ngaphambi kokusetshenziswa, okuvumela ukukhipha ama-debris, izakhi ezingaphandle, amatshe amancane. Phakathi kwezinye izinto, ukuhlanganiswa okomile okumele kusetshenziswe kufanele kusetshenziswe. Okuvame kakhulu kulo msebenzi kusetshenziswe ibanga lamamenti M400. I-plasticizer isetshenziswa, njengomthetho, ngabachwepheshe. Kodwa-ke, amakhosi asekhaya kufanele abuye aqaphele le nxenye, ekwazi ukuthuthukisa izici zekhwalithi ze-monolith. Uma ulungiselela isitshalo samakhemikhali wokuqhafaza phansi, ubukhulu bokubunjwa kumele kubonwe, njengoba lokhu kuyinto ebalulekile. I-Fiber ivame ukungezwa. Kuyinto fiber polypropylene. Uma uhlela ukwenza ukulungiswa esikhathini esithile kamuva, kunconywa ukuba ushiye ukuthengwa kwangaphambili kwesimali. Lokhu kungenxa yokuthi uma igcinwe, ilahlekelwa yizimfanelo zayo. Yingakho ochwepheshe beluleka ukuthi basebenzise kuphela isitimela, esilondolozwe kahle futhi sakhiwa kamuva.

Ukulinganisa kwesixazululo

Uma ufuna ukwenza isisombululo esiphezulu se-screed, amazinga kufanele afundwe kusengaphambili. Kuvela kubo, kanye nakumkhiqizo we-samente kuzoxhomeka kumkhiqizo wokugcina wekhonkrithi. Ngakho-ke, ukuze uthole ingxube yebanga le-M300, ingxenye eyodwa yesimali se-M600, kanye nezingxenye ezintathu zesihlabathi, kumele ifakwe.

Ngodaka lwe-M200, kubalulekile ukusebenzisa ingxenye eyodwa ye-M600 samente nezingxenye ezine zesihlabathi. I-M300 izotholakala uma ufaka ingxenye eyodwa yamasheya angu-M500 no-2 izingxenye zesanti . Kumele uqaphele ukuthi ukuthola wonke amamaki alandelayo okhonkolo okuyingxenye yesimente yamamaki ahlukene asetshenziswayo. Ku-M150, kufanele usebenzise isamente M400, kanye nezingxenye ezintathu zesanti. Ngaphambi kokwenza isisombululo esiphezulu se-screed, inani le-master kufanele libhekwe. Kumele kukhunjulwe ukuthi phansi angeke igcwaliswe nesisombululo esinempawu engezansi M50. Okuvame ukusetshenziselwa imisebenzi enjalo yi-M200.

Izici zokuxuba

Uma unquma ukulungisa isisombululo esiphezulu, ungathola ukulinganisa ngokufunda lesi sihloko. Nokho, kubalulekile ukwazi ukuthi izithako zixubeke kanjani. Kumele kuqashelwe ukuthi izingxenye ezinomile nezomile kufanele zihlanganiswe eziqukathi ezahlukene. Ekuqaleni, kubalulekile ukuxhuma zonke izingxenye ezomile, kufaka phakathi i-fiber, isamente nesihlabathi. Sebenzisa ibanga le-cement yamamitha M 400, ukulixuba nesihlabathi, besebenzisa isilinganiso se-1 kuya ku-3. Ngakho-ke, ama-kilogram ayi-50 kihlabathi ayodingeka 16.7 kg we-samente. Izakhi ezinomile kufanele zixutshwe imizuzu engu-5. Okulandelayo, qhubeka kwelinye ithangi, lapho i-plasticizer namanzi bengezwa khona. Ngesikhwama se-50 kg samakhemikhali kufanele sengezwe ngamagremu angu-190 we-plasticizer. Amanzi kufanele ahlanganiswe ngesamba se-1/3 samasilimenti.

Ingxenye yesithathu kwesikhwama samasenti kuyodinga ukungeza ama-5.6 amalitha amanzi. Uma uhlanganisa udoti olwenziwe phansi (isilinganiso sebanga ngalinye kuboniswe ngenhla), kufanele kuqashelwe ukuthi i-plasticizer izoba ne-0.6 amalitha. Uma unquma ukulungisa isitifiketi uqobo, ubukhulu balo bulethwe kulesi sihloko. Emva kokuqedwa kwazo zonke izenzo ezichazwe ngenhla, kungenzeka ukuthi uqale ukuxuba izingxenye zamanzi, ngoba lokhu, ingxube eyomile kumele yanezelwa kancane kancane esitsheni se-liquide, ngenkathi igqugquzela kahle. Uma uchithela uketshezi ube yingxube eyomile, amaqabunga ayokwakha, futhi ukuwaqeda kamuva kuzoba nzima kakhulu.

Iseluleko esivela kuchwepheshe

Uma unquma ukulungisa isisombululo esilungele wena, inani elinikezwe kulesi sihloko lizokusiza ukuba ufeze inqubo ngaphandle kwamaphutha. Kumele kukhunjulwe ukuthi kunzima kakhulu ukusebenza ngokuvalwa kwezinkomba, phakathi kwezinye izinto, kuthatha isikhathi eside kakhulu ukuphathwa okunjalo. Ngakho-ke, kunconywa ukuthi usebenzise umxube wokuklama noma umshini wokugqoka, ohlonyelwe ibhuloho ekhethekile. Kumele ukhumbule ukuthi ukusetshenziswa kwamathuluzi wamandla kuzokwenza kube lula ukwenza lezi misebenzi ngesikhathi esifushane kakhulu, futhi nakakhulu nangokwemfanelo. Kulokhu, singacabanga ukuthi ukulungiswa kwengxube kuqediwe. Kufanele kukhunjulwe ukuthi ukusebenza ngesisombululo se-viscous kunzima kakhudlwana, kodwa ukuphahlaza phansi ngemuva kokuqina kuncane kakhulu. Ukunciphisa noma ukunciphisa inani lezinsalela ebusweni ngemuva kokuqina kungenziwa ngendlela ehilela ukuphalaza phansi ngamanzi ngesikhathi sesomiso.

Ukunqunywa kwenani lokudoba ukwenza isikhala

Uma uzilungiselela ngokuzenzekelayo udoti ngesisindo esincane esincane, ubukhulu obudinga ukutadisha kusengaphambili. Kodwa-ke, kubalulekile ukuthila inani lempahla yokwakheka phansi. Ekuqaleni, kuyadingeka ukunquma ivolumu yendawo yokwakha, ngoba lokhu, indawo yokugqoka kufanele yande ngokuqina kwesilwane esihlongozwayo. Isibonelo, uma indawo ephansi phansi ingamamitha ayi-40 square, kanti ubukhulu besendlalelo bungalingana no-5 cm, bese kuthi 40 kufanele yande ngo-0.05. Lokhu kuzokunika isibalo se-2. Kungakanani amamitha ayi-cubic yesisombululo okudingekayo ukuze uhlele phansi egumbini elichazwe.

Kodwa kubalulekile ukutadisha, ngaphambi kokulungiselela udoti ukuze uqhekeke phansi, inani lokubunjwa. Isinyathelo esilandelayo ukubala ukuthi isamente nesihlabathi kuzodingeka kangakanani. Ngenxa yokuthi isixazululo senziwa kusukela ku-1 ukuya ku-3, kuzodingeka ukuthi ube ne-1.5 cubic metres of sand kanye no-0.5 cubic metres yamamenti. I-cubic meter yamamenti inomumo olingana no-1,300 kilogram. Lokhu kubonisa ukuthi kuyadingeka ukuthi ama-kilogram ayi-650 ayi-sement emsebenzini, lesi sibalo sibalwa ngokuphindaphinda 0.5 ngo-1.3. Indlela engenhla yenza kube lula ukubala ukusetshenziswa kwesisombululo, esetshenziselwa ukwakha isikhala sendawo esithile. Inkosi izokwazi ukulungiselela kusengaphambili yonke imali edingekayo yokwakha impahla.

Izici zokugcwalisa isikrini

Uma ucabanga ukuthi ungenza kanjani udoti olwenziwe phansi, ubukhulu obudinga ukuba ufunde kahle. Phakathi kwezinye izinto, kubalulekile ukujwayela ubuchwepheshe bomsebenzi. Ekuqaleni, ubuso buphathwa nge-primer, khona-ke ama-beacons afakiwe, isinyathelo esilandelayo ukuvala nokuthululela. Ukubonga kuyadingeka ukuze unikeze isisekelo ngezici ezinhle zokubambelela. Le ndlela ivumela ukusimamisa isakhiwo sepulangwe eligqamile. Uma ubuso bungenasisekelo esiyingozi, ngakho-ke kungcono ukusebenzisa i-primer, kuyilapho kudingeke ukuba usebenzise i-compound engavamile.

Isiphetho

Uma ucabanga ukuthi ungalungisa kanjani isixazululo esisezingeni eliphansi, ukulinganiswa kuboniswe ngenhla. Bazokuvumela ukuba wenze umsebenzi ngokufanele. Kubalulekile hhayi kuphela ukugcina isilinganiso, kodwa futhi ukusetha ama-beacons. Bayoqinisekisa ukuthi ngisho ne-screed. Isixazululo silungiswa ngokushesha ngaphambi kokuthululela.

Ukuze kutholakale ukufakwa kwazo kubalulekile ukulungiselela ingxube ye-gypsum, ebeka ngaphansi kwesisekelo ngamathuluzi okugcoba amancane. Umshini we-screed of floor efudumele, ubukhulu bawo oboniswe ngenhla, kufanele ulungele ngokushesha ngaphambi kokuthululela. Lokhu kuzokuvumela ukuthi usebenze kancane kancane.
