2.1.I-Fine Aggregate
I-aggregate emihle, ngokuvamile isihlabathi, iyingxenye ebalulekile yodaka olomile oluxubile.Ihlinzeka ngevolumu futhi isebenze njengesigcwalisi, ithuthukisa ukusebenza kodaka futhi yehlise inani lempahla kasimende edingekayo.Usayizi wezinhlayiyana nokusatshalaliswa kweqoqo elihle lithonya kakhulu izici zodaka, njengamandla nokuqina.
2.2.Izibophezelo Zesimende
Izibophezelo zikasimende zinesibopho sokuhlinzeka ngokubumbana namandla odaka.Izibophezelo ezivamile zihlanganisa usimende wase-Portland, usimende abahlanganisiwe, nezinye izibophezelo ze-hydraulic.Uhlobo nenani le-binder elisetshenziswe ekwakhiweni linquma amandla odaka nezici zokusetha.
2.3.Izithasiselo
Izithasiselo zisetshenziselwa ukuguqula nokuthuthukisa izakhiwo zodaka olomile oluxubile.Lokhu kungafaka izisheshisi ze-cellulose ethers, retarders, plasticizers, air-entraining agents, nokunye.Izithasiselo zengezwa ngamanani amancane uma kuqhathaniswa kodwa zinomthelela omkhulu ekusebenzeni kodaka, isikhathi sokusetha, nokusebenza ngaphansi kwezimo ezihlukene.
2.4.Amanzi
Amanzi ayingxenye ebalulekile eyenza kube lula ukuxutshwa kwezithako ezomile, okuzivumela ukuthi zenze unamathisele osebenzayo.Isilinganiso samanzi nosimende sibalulekile, njengoba sithinta ukuvumelana kodaka, isikhathi sokusetha, nokusebenza kukonke.
3. Inqubo Yokwakha
Ukwakhiwa kodaka olomile oluxubile kuhilela ukukala ngokucophelela nokuxuba izingxenye ngezilinganiso ezifanele.Inqubo iqala ngokukhethwa kwezinto zokusetshenziswa, okuhlanganisa nokukhetha isamba esihle, izibophezelo zikasimende, izithasiselo, namanzi.Uma izinto sezikhethiwe, zihlanganiswa ngokuvumelana neresiphi oyifunayo.
Izingxenye ezomile (inhlanganisela emihle kanye nezibophezelo zikasimende) ziqala zixutshwe ukuze kuzuzwe ukuhlangana okulinganayo.Ngemva kwalokho, izithasiselo namanzi kufakwa kule ngxube.Inqubo yokuxuba ingase ihluke kuye ngokuthi ukwakheka okuqondile kanye nemishini esetshenzisiwe.Ukuxuba okufanele kubalulekile ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwazo zonke izingxenye, okuthinta ngokuqondile izinga nokusebenza kodaka.
4. Izici Ezithinta Ukwakhiwa
Ukwakhiwa kodaka olomile oluxubile kuthonywa izici ezimbalwa, okuhlanganisa izidingo zokusetshenziswa, izimo zemvelo, nokucatshangelwa kwezindleko.
4.1.Izidingo Zohlelo
Amaphrojekthi wokwakha ahlukene anezidingo ezihlukene zodaka olomile oluxubile.Izinto ezinjengamandla, ukuqina, isikhathi sokusetha, nombala kungase kwehluke ngokusekelwe kuhlelo lokusebenza.Amafomula ayalungiswa ukuze ahlangabezane nalezi zidingo ezithile.Isibonelo, udaka olusetshenziswa ekwakhiweni kwamatshe ludinga izakhiwo ezihlukile kunodaka olusetshenziswa ekufakweni kwamathayili.
4.2.Izimo Zemvelo
Izimo zemvelo, njengezinga lokushisa kanye nomswakama, zingaba nomthelela enqubweni yokwakheka.Lezi zici zithinta isikhathi sokumisa udaka nokusebenza.Ezimweni ezimbi kakhulu, ukwakheka okukhethekile kungase kudingeke ukuze kuqinisekiswe ukusebenza kahle kodaka.
4.3.Izindleko Ukucatshangelwa
Izindleko zezinto kanye nenqubo yokukhiqiza iyonke ingaba nomthelela ezinqumweni zokwakhiwa.Ukulungisa ukwakheka ukuze kuthuthukiswe ukusebenza kahle kwezindleko kuyilapho kugcinwa ukusebenza kuwukucatshangelwa okubalulekile kubakhiqizi.
5. Ukulawulwa Kwekhwalithi
Ukulawulwa kwekhwalithi kuyisici esibalulekile sokukhiqiza udaka olomile oluxubile.Ukuqinisekisa ikhwalithi yomkhiqizo engaguquki kubalulekile ukuze kuhlangatshezwane namazinga emboni kanye nokulindelwe ngamakhasimende.
5.1.Ukuhlola nokuhlaziya
Abakhiqizi benza izivivinyo ezihlukahlukene futhi bahlaziye kukho kokubili izinto zokusetshenziswa kanye nomkhiqizo wokugcina wodaka.Lokhu kuhlola kuhlola izakhiwo ezifana namandla acindezelayo, amandla okunamathela, ukusebenza, nokuqina.Ukulungiswa kokwakheka kungase kudingeke ngokusekelwe emiphumeleni yokuhlolwa.
5.2.Ukuvumelana kwe-Batch-to-Batch
Ukugcina ukungaguquguquki ukusuka kwelinye iqoqo kuye kwelinye kubalulekile ekulawuleni ikhwalithi.Ukuchezuka ekwakhiweni kungaholela ekusebenzeni komkhiqizo okungahambisani.Izinyathelo eziqinile zokulawula ikhwalithi zisiza ukugwema ukungqubuzana okunjalo.
6. Ukwakhiwa Kodaka Okuvamile Okuxubile
Izicelo ezehlukene ezakhiweni zidinga ukwakheka kodaka oluthile.Nazi ezinye izindlela ezivamile zodaka oluxubekile oluxubile kanye nezakhiwo zalo ezibalulekile:
6.1.I-Masonry Mortar
I-masonry mortar isetshenziselwa ukwakhiwa kwezitini noma i-block.Ngokuvamile iqukethe isihlabathi, usimende, futhi ngezinye izikhathi umcako.Ukwakhiwa kuklanyelwe ukuhlinzeka ngokusebenza okuhle, ukunamathela okuqinile, nokumelana nesimo sezulu.
6.2.I-Plaster Mortar
Udaka lwe-Plaster lusetshenziselwa ukuplasta kwangaphakathi nangaphandle kwezindonga nophahla.Yenzelwe ukunikeza isiphetho esibushelelezi nesihlala isikhathi eside.Izithasiselo ezifana nama-retarders zingase zisetshenziselwe ukwelula isikhathi sokusetha sokufaka ukhonkolo.
6.3.I-Tile Adhesive
Udaka olunamathelayo lwethayela lwenzelwe ukunamathisela amathayela ezindaweni ezahlukahlukene.Kudinga ukunamathela okuqinile nokusebenza okuhle kakhulu.Izithasiselo ze-polymer zivame ukufakwa ukuze kuthuthukiswe ukuhlangana nokuvumelana nezimo.
6.4.Udaka Lokuzilinganisa
Udaka oluzilinganisa lusetshenziselwa ukwakha izindawo ezisezingeni kuma-substrates angalingani.Igeleza kalula futhi izileveli ngokwayo, iqinisekisa ukushelela nokuqeda.Izithasiselo ezifana nama-superplasticizers zisetshenziselwa ukufeza izakhiwo ezifiselekayo zokugeleza.
6.5.Lungisa Udaka
Udaka lokulungisa lwenzelwa ukuphetshwa kanye nokulungisa ukhonkolo owonakele noma izindawo eziphakeme zamatshe.Inikeza amandla aphezulu kanye nokuhlangana okuhle kakhulu ku-substrate ekhona.I-Corrosion inhibitors ingase yengezwe ukuze kuqiniswe ukuqina.
6.6.I-Insulation Mortar
I-insulation mortar isetshenziswa ezinhlelweni zokufakelwa kwe-thermal zangaphandle (ETICS) ukunamathisela amabhodi okufakwa ezindongeni.Inezici ezithile zokuqinisekisa ukusebenza okushisayo kwe-insulation.Ama-aggregate angasindi avame ukufakwa ukuze kuncishiswe ukudluliswa kokushisa.
7. Isiphetho
Ukwakhiwa kodaka oluxutshwe okomile kuyinqubo eyinkimbinkimbi ehlanganisa inhlanganisela enembile yenhlanganisela enhle, izibophezelo zikasimende, izithasiselo, namanzi ukuze kudalwe into yokwakha ehambisana nezinhlelo zokusebenza ezithile.Ukuqonda indima yengxenye ngayinye nokucabangela izici ezifana nezidingo zohlelo lokusebenza, izimo zemvelo, nezindleko kubalulekile ekukhiqizeni udaka olomile oluxubile lwekhwalithi ephezulu.Izinyathelo zokulawula ikhwalithi ziqinisekisa ukusebenza komkhiqizo okungaguquki futhi zihlangabezana namazinga omkhakha.Ukusetshenziswa kokwakheka kodaka olomile okuxubile kusabalele ezinhlelweni zokwakha ezahlukahlukene, kusukela ekuqoqweni kwamatshe kanye ne-plastering kuya kuma-adhesive amathayili kanye nezinhlelo zokufakelwa, okugqamisa ukubaluleka kwayo embonini yesimanje yokwakha.
8. Izikhombo
Sicela uqaphele ukuthi ithebula eliqukethe ukwakheka kwedaka elomile elixutshiwe lezinhlelo zokusebenza ezihlukahlukene alifakiwe kule mpendulo ngenxa yobubanzi balo.Uma ungathanda ithebula elinemininingwane, sicela unikeze imininingwane ethile mayelana nokwakheka onentshisekelo kukho, futhi ngingakusiza ekudaleni ithebula elisuselwe kulolo lwazi.
