(Imiba ephambili xa ukhetha i-Concrete Admixtures)

Ukukhetha umxube ochanekileyo wekhonkrithi kubonakala ngathi upheka ikhekhe. Ufuna eyona ngxubevange yezithako ezisebenzayo. I-concrete admixtures zezo zithako ezisebenzayo ezizodwa. Bayilungisa kakuhle imikhwa yekhonkrithi. Oku kwenza iiprojekthi zokwakha zibe lula, ngokukhawuleza, kwaye womelele. Ukukhetha engalunganga? Oko kufana nokuquka ityuwa endaweni yeswekile. Ukuqonda izinto eziguquguqukayo ezibalulekileyo kukhusela kwiimpazamo ezibizayo. Makhe singene kwinto eyenza ezi zithako zibaluleke kangaka.

Yintoni imixube Concrete? .

I-concrete admixtures ziyizithako ezikhethekileyo. Babandakanywa kumxube wekhonkrithi. Oku kwenzeka ngaphambi okanye ngexesha lonke lokuxuba. Umsebenzi wabo ulula. Batshintsha iimpawu zekhonkrithi entsha okanye enzima. Zigqale njengezongezeleli ezisebenzayo.

1. Ziza zikulwelo okanye zingumgubo. Abasebenzi bongeza ngokuthe ngqo kwilori yekhonkrithi okanye kwiplanti yokuxuba. Ubungakanani obandakanyiweyo buncinci. Ngokuqhelekileyo yipesenti ezimbalwa zobunzima besamente. Kodwa le pesenti yenza umahluko omkhulu.
2. Imixube ilungisa imiba eqhelekileyo. Mhlawumbi iimfuno zekhonkrithi zokusasaza ngcono ngakumbi malunga ne-tight rebar. Mhlawumbi ifuna ukusekwa ngokukhawuleza ngemini epholileyo. Imixube yenza olu hlengahlengiso lube nokwenzeka. Zizixhobo ezibalulekileyo zokwakha kule mihla.
3. Kukho iintlobo ezininzi. Uhlobo ngalunye lujolise kwiipropati ezibambekayo zokuhlala. Abanciphisi bamanzi benza umxube uhambe ngcono ngaphandle kwamanzi angaphezulu. Ii-accelerators zikhawulezisa ixesha lokuseta. Ababuyiseli bayayinciphisa phantsi. Abangenisi bomoya baquka amaqamza amancinci okumelana nokunyibilika komkhenkce. Iiplastiki zeplastiki ziphucula ukusebenza kakuhle. Uluhlu luyaqhubeka.
4. Ukusebenzisa imixube kufuna ukhathalelo. Kufuneka ulandele imiyalelo yomthengisi. Ukudibanisa ixesha kunye nombandela womyalelo. Ukubandakanya indlela eninzi kakhulu kunokuba kubi kunokuba ungongezi nanye. Ukudibanisa okuchanekileyo kuqinisekisa ukuba i-admixture isebenza ngokuchanekileyo.
5. Asiyondlela yokutshintsha ngokupheleleyo. Iimveliso ezisemgangathweni kunye nonyango oluchanekileyo zisabalulekile. Imixube yongeza ubuchule obugqwesileyo. Abajongani nezimbi. Cinga ngabo njengabancedi, hayi abakhohlisi.

Kutheni Usebenzisa Imixube ebambekayo? .

Kutheni uzikhathaza ngale michiza yongezelelweyo? Iinzuzo zicacile. Benza ikhonkrithi ibe lula kakhulu ukusebenza nayo. Baphucula umgangatho ophezulu wemveliso yokugqibela. Bagcina imali kunye nexesha.

1. Ukusebenza ngcono kakhulu ngumba ophambili. Iimfuno zekhonkrithi zibe lula kwindawo kunye nokugquma. Ukongeza amanzi amaninzi kuwenza umsinga ube ngcono. Kodwa amanzi ongezelelweyo ayonakalisa ikhonkrithi. I-admixtures yokunciphisa amanzi isebenzisa inketho. They let the concrete flow smoothly without weakening it. Employees can put concrete quicker and with much less initiative.
2. Managing setting time is important. Think of a hot summer day. The concrete may set also quick. Workers have a hard time to finish it smoothly. A retarder admixture reduces this down. It provides even more time for putting and finishing. Ngokuchaseneyo, in winter, an accelerator aids the concrete collection faster. This protects it from cold damage.
3. Improved durability is a crucial benefit. Concrete faces many adversaries. Cold and thawing cycles can fracture it. Chemicals like deicing salts strike it. Air-entraining admixtures produce small air bubbles. These bubbles provide water area to broaden when frozen. This stops fracturing. Various other admixtures can make concrete more immune to chemicals.
4. Ukufumana amandla aphezulu kunokwenzeka. Abanciphisi bamanzi bavumela amanzi amancinci kumxube. Amanzi amancinci kakhulu athetha ikhonkrithi eyomeleleyo. Ezinye ii-admixtures zandisa ngokukhawuleza inkqubo yokuqinisa. Oku kubangela amandla aphezulu kwangoko okanye okugqibela. Ikhonkrithi enamandla ngakumbi ithetha iindawo ezibhityileyo okanye izikhonkwane ezinde.
5. Iindleko zokongiwa kwemali ziyongeza. Ukubeka indawo ngokulula konga ixesha labasebenzi. Ukuqina okuphezulu kunokuthetha ukusebenzisa i-concrete encinci kakhulu. Amaxesha okuseta ngokukhawuleza avumela ukupheliswa kobubele ngokukhawuleza. Iiprojekthi ziphela ngokukhawuleza. Ukuyeka iingxaki zokuqina kuthintela umsebenzi wokulungisa onexabiso eliphantsi kamva. Inkcitho encinci ye-admixture ihlala izisa ukonga imali enkulu.

Ngokuchanekileyo indlela yokukhetha uMxube oLungileyo? .

Ukukhetha akukho malunga nokufumana naluphi na uhlobo lwebhotile. Ufuna iqhinga. Umxube ofanelekileyo uxhomekeke ngokupheleleyo emsebenzini.

1. Cacisa iimfuno zeprojekthi kuqala. Ziziphi iingxaki ezinkulu? Ngaba ukubeka ikhonkrithi kuhlobo oluntsonkothileyo? Ke ukusebenza okuphezulu kubalulekile. Ngaba yidekhi yebhulorho edibana nexesha lasebusika? Emva koko ukuxhathisa ukunyibilika komkhenkce kuyimfuneko. Mhlawumbi i-slab kufuneka ilungele ukuhamba kwewebhu ngokukhawuleza. Ke ukuseta ngokukhawuleza kubalulekile. Dwelisa eziphambili 2 okanye iimfuno ezintathu zokusebenza.
2. Ziqaphele iimeko zokusingqongileyo. Iqondo lobushushu lidlala umsebenzi omkhulu. Imozulu eshushu idla ngokufuna abantu abarhabaxa. Ubusika budla ngokufuna ii-accelerators. Ukufuma okuphezulu kuchaphazela ixesha lokuseka. Iingxaki ezinomoya zingomisa umphezulu ngokukhawuleza. Khetha imixube ephendula le miphumo.
3. Yazi isimbo somxube wekhonkrithi. Uhlobo lwesamente lubalulekile. Ezinye iikhonkrithi zisabela ngokwahlukileyo kunye nemixube ethile. Ubungakanani bamanzi, isanti, kunye negrabile ichaphazela indlela umxube osebenza ngayo. Ithagethi ye-slump ikhokela ukhetho lokunciphisa amanzi okanye iplastiki. Yabelana ngoyilo lomxube kunye nomthengisi we-admixture.
4. Qhagamshelana nomthengisi we-admixture kwangoko. Ziingcali. Xoxa ngeprojekthi. Bazise iinkcukacha zesimbo sokuxuba. Thetha ngemozulu. Isicelo sokuthunyelwa kwabo. Banokucebisa olona hlobo lulungileyo kunye nomthamo. Banokucebisa malunga neengxabano ezinokubakho.
5. Uviwo, uviwo, uviwo! Ungaze uxhomekeke ekungaqiniseki. Yenza iiseti zovavanyo usebenzisa ezona mathiriyeli. Vavanya ikhonkrithi entsha. Hlola ukusebenza kwayo kunye nexesha lokumisela. Vavanya ikhonkrithi eqinileyo yokuqina kunye nokuqina. Qinisekisa imisebenzi ye-admixture njengoko kulindelekile. Qinisekisa ukuba ayibangeli naziphi na iziphumo ezibi ezingafunekiyo.

Usetyenziso lweentlobo ezahlukeneyo zomxube? .

Iiprojekthi ezahlukeneyo zifuna izisombululo ezahlukeneyo. Uhlobo ngalunye lwe-admixture lukhanya kwiimeko zeenkcukacha.

1. Izinciphisi zamanzi kunye neeplasticizers zikho kuyo yonke indawo. Bakhuthaza ukusebenza kwindawo enzima kakhulu. Oku kubalulekile ekumpompeni amazwe anqamlezileyo ekhonkrithi. Kuyimfuneko ukubeka ikhonkrithi kumacandelo aqiniswe kakhulu. Izakhiwo eziphakamileyo, iibhulorho, kunye nezakhiwo zonke inzuzo.
2. Ii-accelerator zezengqele. Bakhawulezisa ukusetha kunye nokufumana amandla kwangoko. Zisebenzise xa amaqondo obushushu ehla ngaphantsi 50 ° F (10 °C). Bancedisa ekulungiseni imeko engxamisekileyo efuna ukuguqulwa ngokukhawuleza. Izityalo zesankrithi ezifakwe ngaphambili zisebenzisela ukungunda ngokukhawuleza kunye nokuphinda kusetyenziswe ukungunda.
3. Ababuni bajongana nobushushu. Balibazisa ekungeneni kwimozulu eshushu. Oku kunika ixesha elingakumbi lokubeka amaqhekeza amakhulu okanye izinto ezintsonkothileyo zokwakha. Zikhusela kumalungu abandayo kwiindawo ezinkulu. Zisebenzise xa izithuthi ezibambekayo zixinga kwisithuthi ngemini eshushu.
4. Imixube yokungenisa umoya ikhusela ekunyibilikeni komkhenkce. Zinyanzelekile kwikhonkrithi ephantsi kwemeko yemozulu ebandayo kunye namanzi. Cinga iindlela zokuhamba, iindlela zokuhamba, iminqantsa, iidekhi zebhulorho, kunye namadama. Amaqamza omoya amancinci akhusela ukuqhekeka kuphuhliso lomkhenkce.
5. Imixube ekhethekileyo ilungisa iingxaki ezikhethekileyo. Uthintelo lomhlwa lukhusela i-rebar kwiibhulorho okanye kwiigaraji zokupaka ezivezwe kwityuwa. Izinciphisi ezicuthayo zinciphisa ukuqhekeka kwiziqwenga ezinkulu zomgangatho. Izixhobo zokumpompa zinceda ukuhambisa ikhonkrithi ngokufanelekileyo kwimibhobho emide. I-admixtures yokukhusela amanzi idibanisa ukunyanzeliswa okuphantsi kweendawo ezingaphantsi okanye iitanki zamanzi.

FAQs Malunga neConcrete Admixtures? .

Abantu bahlala benenkxalabo malunga nezi zithako. Nazi ezinye eziqhelekileyo.

1. Ngaba imixube yenza ikhonkrithi ibe buthathaka? Hayi. Isetyenziswe ngokufanelekileyo, uninzi lwenyani luyenza ibe namandla ngakumbi.
