Udaka oluyimpushana olomile luwudaka oluqedwe kancane olwenziwa ngezinto ezingavuthiwe efektri ngokuhlanganisa okunembile nokuxuba imifaniswano. Ingasetshenziswa kuphela ngokungeza amanzi nokunyakazisa endaweni yokwakha. Ngenxa yezinhlobonhlobo ze-powder mortar, isetshenziswa kabanzi. Esinye sezici zayo ezinkulu ukuthi ungqimba lwayo oluncane ludlala indima yokubopha, ukuhlobisa, ukuvikela kanye nokuhlanganisa. Isibonelo, udaka olunomsebenzi oyinhloko wokuhlanganisa ikakhulukazi udaka lwamatshe, udaka lwamathayela odonga naphansi, udaka olukhomba, udaka oluqinile, njll.; udaka olunomphumela oyinhloko wokuhlobisa ikakhulukazi luhlanganisa izinsika ezihlukahlukene zokukhonkoloza, i-putty yezindonga zangaphakathi nezangaphandle, nodaka lokuhlobisa olunemibala. njll.; udaka olungangeni manzi, udaka oluhlukahlukene olumelana nokugqwala, udaka oluzilinganisa phansi, udaka olungagugi, udaka olubamba ukushisa okushisayo, udaka olumunca umsindo, udaka lokulungisa, udaka oluvikela isikhutha, udaka oluvikelayo, njll. Ngakho-ke, ukwakheka kwayo kuyinkimbinkimbi, futhi ngokuvamile yakhiwe ngezinto zokuhlanganisa, ukugcwalisa, i-mineral admixture, i-pigment, i-admixture nezinye izinto.
1. Isibopho
Izinto zikasimende ezisetshenziswa kakhulu uma kwenziwa udaka olomile yilezi: usimende wasePortland, usimende wasePortland ojwayelekile, usimende we-alumina ephezulu, usimende we-calcium silicate, igypsum yemvelo, umcako, intuthu yesilika nezingxube zalezi zinto. I-Portland Cement (imvamisa yohlobo I) noma usimende omhlophe wase-Portland yizona ezihlanganisayo. Amanye usimende akhethekile ngokuvamile adingeka odakeni lwaphansi. Inani le-binder lihlanganisa u-20%~40% wekhwalithi yomkhiqizo wengxube eyomile.
2. Isigcwalisi
Izithako eziyinhloko zodaka lwempuphu eyomile yilezi: isihlabathi esiphuzi, isihlabathi se-quartz, i-limestone, i-dolomite, i-perlite enwetshiwe, njll. Lezi zigcwalisi zichotshozwa, zomiswe, bese zihlungwa zibe izinhlobo ezintathu: ezimahhadla, eziphakathi, nezicolekileyo. Usayizi wezinhlayiyana yilokhu: isigcwalisi esimahhadla 4mm-2mm, isigcwalisi esiphakathi esingu-2mm-0.1mm, nesigcwalisi esihle esingaphansi kuka-0.1mm. Emikhiqizweni enosayizi wezinhlayiyana ezincane kakhulu, impushana yetshe elicolisekile kanye ne-limestone ehlungiwe kufanele kusetshenziswe njengezihlanganisi. Udaka olujwayelekile lwempuphu eyomile lungasetshenziswa hhayi kuphela i-limestone echotshoziwe, kodwa nesihlabathi esomisiwe nesihlungiwe njenge-aggregate. Uma isihlabathi sinekhwalithi eyanele ukuthi sisetshenziswe kukhonkolo yesakhiwo sezinga eliphezulu, kufanele sihlangabezane nezidingo zokukhiqiza izingxube ezomile. Isihluthulelo sokukhiqiza udaka oluyimpushana olomile olunekhwalithi enokwethenjelwa lusekwazisweni kobukhulu bezinhlayiyana zezinto ezingavuthiwe kanye nokunemba kwesilinganiso sokuphakelayo, esitholakala emgqeni wokukhiqiza ozenzakalelayo we-powder mortar.
3. Izixube zamaminerali
Izixube zamaminerali zodaka lwempuphu eyomile ikakhulukazi: imikhiqizo ephuma ezimbonini, imfucumfucu yezimboni kanye nensimbi ethile yemvelo, njengalezi: i-slag, umlotha wempukane, umlotha wentaba-mlilo, impushana ye-silica ecolekile, njll. Ukwakheka kwamakhemikhali kwalezi zingxube ikakhulukazi i-silicon equkethe i-calcium oxide. I-Aluminium hydrochloride inomsebenzi ophezulu kanye nobulukhuni be-hydraulic.
4. Inhlanganisela
I-admixture iyisixhumanisi esiyinhloko se-powder mortar eyomile, uhlobo kanye nenani le-admixture kanye nokuguquguquka phakathi kwezixube kuhlobene nekhwalithi nokusebenza kwe-powder mortar eyomile. Ukuze kwandiswe ukusebenza kanye nokuhlangana kodaka lwempushana eyomile, kuthuthukiswe ukumelana nokuqhekeka kodaka, kunciphise ukungena kwamanzi, futhi kwenze udaka lungabi lula ukopha nokuhlukaniswa, ukuze kuthuthukiswe ukusebenza kokwakhiwa kodaka lwempushana eyomile futhi kunciphise izindleko zokukhiqiza. Okufana ne-polymer rubber powder, i-wood fiber, i-hydroxymethyl cellulose ether, i-hydroxypropyl methyl cellulose, i-polypropylene fiber eguquliwe, i-PVA fiber kanye nama-agent ahlukahlukene okunciphisa amanzi.
