Udaka vs Concrete

Udaka kunye nekhonkrithi zizinto ezimbini eziqhelekileyo ezisetyenziswa kushishino lokwakha.Zombini zenziwe ngesamente, isanti, namanzi, kodwa umlinganiselo wesithako ngasinye uyahluka, nto leyo enika imathiriyeli nganye iimpawu zayo ezizodwa kunye nokusetyenziswa kwayo.Kweli nqaku, siza kuxubusha umahluko phakathi kodaka kunye nekhonkrithi, iimpawu zazo kunye nokusetyenziswa kwazo.

Udakangumxube wesamente, isanti namanzi.Isetyenziswa ngokuqhelekileyo njengento yokudibanisa phakathi kwezitena, amatye, okanye ezinye iiyunithi zobumba.I-Mortar yinto ebuthathaka ngokulinganayo kunye namandla oxinzelelo ukusuka kwi-2.5 ukuya kwi-10 N / mm2.Ayenzelwanga ukuba ithwale imithwalo enzima, kodwa kunokuba ibambe iiyunithi ze-masonry kunye nokubonelela ngomphezulu ogudileyo wokugqiba.

Ubungakanani besamente, isanti, kunye namanzi eludaka luxhomekeke kwisicelo kunye neempawu ezifunwayo.Ngokomzekelo, umxube oqhelekileyo wokubeka izitena yi-1 inxalenye yesamente ukuya kwi-6 inxalenye yesanti, ngelixa umxube wokunikezela ngeendonga yi-1 inxalenye yesamente ukuya kwi-3 inxalenye yesanti.Ukongeza i-lime kumxube kunokuphucula ukusebenza, ukuqina, kunye nokuxhathisa kwamanzi omdaka.

Ikhonkrithi yona, ngumxube wesamente, isanti, amanzi kunye nezinto ezidityanisiweyo, njengegrabile okanye amatye atyunyuziweyo.Yinto eyomeleleyo kunye neyomeleleyo enamandla okunyamezela ukusuka kwi-15 ukuya kwi-80 N / mm2, kuxhomekeke kwimilinganiselo yokuxuba kunye nomgangatho wezithako.Ikhonkrithi isetyenziselwa uluhlu olubanzi lwezicelo, ezifana neziseko, imigangatho, iindonga, imiqadi, iintsika, kunye neebhulorho.

Ubungakanani besamente, isanti, amanzi, kunye neeaggregates zekhonkrithi zixhomekeke kwisicelo kunye namandla afunekayo kunye nokuqina.Umxube oqhelekileyo wokwakhiwa ngokubanzi yi-1 inxalenye yesamente ukuya kwi-2 inxalenye yesanti ukuya kwi-3 i-aggregates ukuya kwiindawo ezi-0.5 zamanzi, ngelixa umxube we-concrete eqiniweyo yi-1 inxalenye yesamente ukuya kwi-1.5 inxalenye yesanti ukuya kwi-3 inxalenye yamanzi.Ukongeza i-admixtures, njengeplastiki, i-accelerators, okanye i-air-entraining agents, inokuphucula ukusebenza, amandla kunye nokuqina kwekhonkrithi.

Omnye umahluko omkhulu phakathi kodaka kunye nekhonkrithi ngamandla azo.Ikhonkrithi yomelele kakhulu kunodaka, okwenza ukuba ilungele ukuthwala imithwalo enzima kunye nokumelana nemikhosi yoxinzelelo.Udaka, kwelinye icala, lubuthathaka kwaye lubhetyebhetye ngakumbi, oluvumela ukuba lufunxe ezinye zoxinzelelo olufunyanwa ziiyunithi ze-masonry ngenxa yokutshintsha kobushushu, ukwandiswa komswakama, okanye intshukumo yesakhiwo.

Omnye umahluko kukusebenza kwabo.I-Mortar ilula ukusebenza ngaphezu kwekhonkrithi, njengoko ine-viscosity ephantsi kwaye ingasetyenziswa nge-trowel okanye isixhobo sokukhomba.Udaka nalo luseta ngokucothayo kunekhonkrithi, nto leyo enika umenzi wamatye ixesha elingakumbi lokulungelelanisa indawo yeeyunithi zobumesi phambi kokuba udaka lube lukhuni.Ikhonkrithi, ngakolunye uhlangothi, kunzima kakhulu ukusebenzisana nayo, njengoko ine-viscosity ephezulu kwaye idinga izixhobo ezikhethekileyo, ezifana neepompo zekhonkrithi okanye i-vibrators, ukuba zibekwe kwaye zihlanganiswe ngokufanelekileyo.Ikhonkrithi iphinda ibeke ngokukhawuleza kunodaka, olunciphisa ixesha elikhoyo lohlengahlengiso.

Udaka kunye nekhonkrithi nazo ziyahluka kwinkangeleko yazo.Udaka ludla ngokuba khaphukhaphu ngombala kunesamente, kuba lunesamente encinane nesanti eninzi.Udaka lunokufakwa imibala ngee-pigments okanye amabala ukuhambelana nombala weeyunithi zobumba okanye ukwenza iziphumo zokuhombisa.Ikhonkrithi, kwelinye icala, idla ngokuba ngwevu okanye imhlophe, kodwa inokuba nombala ngeepigments okanye amabala ukufezekisa inkangeleko ethile.

Ngokwexabiso, udaka luxabisa kakhulu kunekonkrithi, njengoko lufuna isamente encinci kunye neeaggregates.Nangona kunjalo, iindleko zomsebenzi zinokuhluka ngokuxhomekeke kubunzima kunye nobukhulu beprojekthi, kunye nokufumaneka kwamasons anezakhono okanye abasebenzi bekhonkrithi.

Ngoku makhe sijonge ngakumbi kwizicelo kunye nokusetyenziswa kodaka kunye nekhonkrithi.Udaka lusetyenziswa ngokuyintloko njengesixhobo sokudibanisa phakathi kweeyunithi zobumeli, njengezitena, iibhloko, amatye, okanye iithayile.Ikwasetyenziselwa ukulungisa okanye ukuchwetheza isakhi samatye esele sikhona, kwanangeenjongo zokuhombisa, ezinjengokwalatha, ukunikezela, okanye ukutyabeka.Udaka lunokusetyenziswa kuzo zombini iindawo zangaphakathi kunye nezangaphandle, kodwa alufanelekanga iinjongo zesakhiwo okanye imithwalo enzima.

Ikhonkrithi, kwelinye icala, isetyenziselwa uluhlu olubanzi lwezicelo, ukusuka kwiiprojekthi ezincinci ukuya kwiziseko ezingundoqo.Ukusetyenziswa okuqhelekileyo kwekhonkrithi kubandakanya:

Iziseko: Ikhonkrithi isetyenziselwa ukwenza isiseko esizinzileyo kunye nenqanaba lezakhiwo, iibhulorho, okanye ezinye izakhiwo.Ubunzima kunye nobunzulu besiseko buxhomekeke kwiimeko zomhlaba kunye nobunzima besakhiwo.
Umgangatho: Ikhonkrithi inokusetyenziselwa ukwenza imigangatho ehlala ixesha elide kunye nephantsi yokulungiswa kwezakhiwo zokuhlala, zorhwebo, okanye izakhiwo zoshishino.Inokupholiswa, ifakwe ibala, okanye isitampu ukuze ifezekiseke ngeendlela ezahlukeneyo.
Iindonga: Ikhonkrithi inokuphoswa kwiipaneli ze-precast okanye igalelwe kwisiza ukwenza iindonga ezithwele okanye ezingathwali mthwalo.Ingasetyenziselwa ukugcina iindonga, izithintelo zesandi, okanye iindonga zomlilo.
Imiqadi kunye neentsika: Ikhonkrithi inokuqiniswa ngeentsimbi zentsimbi okanye iintsinga ukuze zenze imiqadi eyomeleleyo neqinileyo kunye neentsika zokuxhasa izakhiwo.Ingasetyenziselwa izinto ezingaphambili, njengezitebhisi okanye iibhalkhoni.
Iibhulorho kunye neendlela: Ikhonkrithi yinto eqhelekileyo yokwakha iibhulorho, oohola bendlela, kunye nezinye iziseko zothutho.Iyakwazi ukumelana nemithwalo enzima, iimeko zemozulu ezinzima, kunye nokuguga kwexesha elide.
Izinto zokuhombisa: Ikhonkrithi ingasetyenziselwa ukudala izinto ezahlukeneyo zokuhombisa, njengemifanekiso eqingqiweyo, imithombo, iiplanti, okanye iibhentshi.Inokuthi ibe nombala okanye i-textured ukulinganisa ezinye izinto, ezifana nemithi okanye ilitye.

Ukuqukumbela, udaka kunye nekhonkrithi zizinto ezimbini ezibalulekileyo kwishishini lokwakha, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo.Udaka sisixhobo esibuthathaka kwaye sibhetyebhetye ngakumbi esisetyenziselwa ukudibanisa iiyunithi zobumba kunye nokubonelela ngesiphelo esigudileyo, ngelixa ikhonkrithi iyimathiriyeli eyomeleleyo nengqongqo ngakumbi esetyenziselwa inkxaso yesakhiwo kunye nemithwalo enzima.Ukuqonda umahluko nokusetyenziswa kodaka nekonkile kunokunceda abakhi bezakhiwo, iinjineli, iikontraka, nabaninimzi benze izigqibo ezisekelwe kulwazi ngomsebenzi wabo wokwakha.
