Njengoba ukwakhiwa komhlaba wonke kuhamba ngasekuphumeni kwekhabhoni ephansi namazinga aphezulu okusebenza, izithako zikakhonkolo sezibalulekile ezinhlelweni zokwakha ezisimeme. Abakhiqizi nabasontisi manje bathembele ezithakweni ukuze balungise izinhlanganisela, banciphise okuqukethwe usimende, futhi bathuthukise ukuqina ngenkathi kugcinwa ukusebenza esizeni. Ezinkampanini ezifuna ozakwethu abathembekile, iDezhou Zhongke New Materials Co., Ltd. inikeza iqoqo lezithako eziklanyelwe ukuhlangabezana nezindinganiso zesimanje zokuzinza ngaphandle kokudela ukusebenza. Lesi sihloko sihlola izinselele zokukhiqiza ukhonkolo, izixazululo ezintsha zezithako ezifana nezithako ezinciphisa amanzi nezithako ezinciphisa ukuncipha, izindinganiso ezifanele zokuzinza ezihlanganisa izitatimende zemikhiqizo yemvelo (EPDs), kanye nezinga elibumba ubuhlakani buka khonkolo.

Ukhonkolo usalokhu uyimpahla yokwakha esetshenziswa kakhulu emhlabeni wonke, kodwa ukukhiqizwa kwawo kubangela ukukhishwa okukhulu kwe-CO2 ngenxa yokukhiqizwa kukasamente. Izithako ezingezekayo zinikeza indlela esebenzayo yokunciphisa ikhabhoni eliboshiwe ngokuvumela ukusetshenziswa kukasamente okuncane nokuqina okuthuthukisiwe esikhathini eside. Izithako eziphansi kakhulu zamanzi kanye nezithako eziphakathi zamanzi ezinciphisa amanzi zivumela amandla alingana noma angcono ngosamente omncane, okunciphisa ngqo ubukhulu bekhabhoni. Izithako ezithwala umoya zithuthukisa ukumelana nokuqhwa nokuqhakaza emakhazeni, zandisa impilo yesakhiwo futhi zinciphise ukukhishwa kwezinto ezibangela ukulungiswa nokushintshwa. Kubaqeqeshi bamaphrojekthi abagxile ezinhlosweni zokusimama, ukukhetha kahle amakhemikhali ezithako ezingezekayo kubaluleke njengokukhetha izinto zokwakha kanye nezinhlobo zikasamente.

Ukwenziwa kukakhonkolo kuhlangabezana nokuguquguquka ezintweni ezisetshenziswayo—amakhemikhali esimentini, ukuhlelwa kwamatshe, kanye nekhwalithi yamanzi—ezithinta izakhiwo ezintsha nezilukhuni. Izinto ezingahambisani ziholela ekuguquguqukeni kokusebenza, isikhathi sokuqina, nentuthuko yokuqina, okwandisa ubungozi esizeni futhi kungadala ukwenziwa kabusha. Ama-retarder nama-accelerator kakhonkolo avame ukusetshenziswa ukuphatha amawindi okubeka nokwelapha, ikakhulukazi emazingeni okushisa aphezulu noma izikhathi ezinde zokuhamba. I-shrinkage reducing admixture ibalulekile lapho kulawulwa ukuncipha kokomisa kumix ezingeni eliphansi lamanzi kuya kumentini ukuvimbela ukuqhekeka nokugcina ukuqina. Ngokukhokhela ukuguquguquka kwezinto, ama-admixture asiza ukuqinisekisa ukusebenza okuhambisanayo kuwo wonke ama-batch, kunciphisa ukuchitha nokuthuthukisa ukubikezelwa kwabakhi nabakhiqizi be-precast.

Izithako zesimanje zidlula imiphumo elula yokwenza ukhonkolo lube lula. Abanciphisi bamanzi abathuthukisiwe kanye nama-superplasticizers enza izixube zamandla aphezulu ngokuqukethwe okuncane kwe-cementitious, kanti izithako ezinciphisa ukuncipha (SRA) kanye nama-ejenti okwelapha ngaphakathi anciphisa ingcindezi ye-tensile ngesikhathi sokomisa. Ama-ejenti okungenisa umoya abalulekile ukuqina kwesikhathi eside ezindaweni zokuqhwa nokuqhakaza futhi athuthukisa izici zokuqeda ezindaweni eziveziwe. Ama-retarder akhethekile enza ukusebenza okwandisiwe kokuthululwa isikhathi eside noma ukwakhiwa kwekhonkolo ngesikhathi sezulu esishisayo, futhi ama-accelerator okubeka enza ukujikeleza okusheshayo kwe-formwork, anciphisa izinhlelo zokwakha futhi anciphise ukusetshenziswa kwamandla esizeni. I-Dezhou Zhongke New Materials Co., Ltd. yenza izithako ukulinganisa lezi zici zokusebenza, yenza imikhiqizo ibe yimikhiqizo eyenziwe ngaphambili, ilungele ukuthululwa, kanye nezixube ezikhethekile ze-cement ukuze kuhlangatshezwane nezidingo zobuchwepheshe kanye nemigomo yokusimama.

Izitatimende Zemikhiqizo Yemvelo (EPDs) amadokhumenti aqinisekiswe yizinhlangano ezizimele, anquma umthelela wezemvelo wezinto zokwakha kulo lonke uhambo lwazo. Ezotoni kanye nezithako zazo, ama-EPD abonisa ikhabhoni egxilile, ukusetshenziswa kwamandla, nezinye izigaba zomthelela, avumela abacacisi ukuthi benze izinqumo ezinolwazi. Lapho kusetshenziswa izithako ezinciphisa amanzi noma ezikhulisa amandla ezivumela ukuncishiswa kukasamente, ukuhlaziywa kwe-lifecycle okusekelwe ku-EPD kungabonisa ukonga okubalulekile kwe-CO2. Abakhiqizi bezithako banyathelisa ama-EPD namashidi edatha yobuchwepheshe ngokwanda ukuze basekele ukuthengwa okusimeme kanye nezitifiketi zokwakha eziluhlaza. Ngokukhetha izithako ezinama-EPD acacile nokusebenza okuqinisekisiwe, amaqembu ephrojekthi angasekele izimangalo zekhabhoni ephansi egxilile nokuqina okuthuthukisiwe kwe-lifecycle.

Izitayela eziningana ziguqula ubuchwepheshe be-concrete. Okokuqala, ukuklama okudijithali kanye nezinhlelo zokulinganisa ezizenzakalelayo kuvumela ukufakwa okunembayo kwezithako ukuze kuthuthukiswe ukusebenza futhi kuncishiswe ukuchitha. Okwesibili, izinto zokwakha ezisekelwe ezintweni eziphilayo kanye ne-low-VOC zivela ukunciphisa umthelela emvelweni nokuthuthukisa ukuphepha kwabasebenzi. Okwesithathu, izithako ezivumela ukusetshenziswa kwezinto ezingeziwe eziningi (SCMs) ezifana ne-fly ash, i-slag, noma ubumba olushiswe ngomlilo kusiza ukunciphisa isidingo se-clinker kanye ne-embodied carbon. Okwesine, ukuhlolwa kokuhambisana phakathi kwezithako namasamente angaphandle kuyaba yinto ejwayelekile ukugwema ukusebenzisana okungalindelekile. I-Dezhou Zhongke New Materials Co., Ltd. itshala imali ku-R&D kanye nezivivinyo zasensimini ukuqinisekisa ukuhambisana komkhiqizo nezingxube ezicebile nge-SCM nokusekela amaklayenti asebenzisa izibopho ezilandelayo ezisezingeni eliphansi lekhabhoni.

Ukusetshenziswa okuphumelelayo kwezithako ezingezekayo kudinga indlela ethize yepulojekthi. Qala ngezicelo ezisekelwe ekusebenzeni—amandla acatshangelweyo, ukuqina, ukusebenza kalula, nokuncipha okwamukelekayo—kunokuyala izilinganiso ezimisiweyo. Yenza izilinganiso zokuhlola ngaphansi kwezimo zangempela ezilindelekile ukuze uhlole ukusebenzisana nezinsalela zasendaweni, amanzi, namakhemistri kasimende. Faka izidingo ze-EPD nedatha yezobuchwepheshe emibhalweni yokuthenga ukuze uqinisekise ukubonakala kokusimama. Ezimweni ezinkulu zokukhiqiza izinto zokwakha ezifakwe ngaphambili, ukulinganisa okuzenzakalelayo nokulawula ikhwalithi ngesikhathi sangempela kunciphisa ukuhluka kusuka ku-batch kuye ku-batch. I-Dezhou Zhongke New Materials Co., Ltd. ihlinzeka ngosekelo lobuchwepheshe, izilinganiso zokuhlola endaweni, nokuqeqeshwa ukusiza abakhiqizi nabasayine ukuthi bafinyelele imiphumela ehambisanayo ngenkathi behlangabezana nezinjongo zokusimama.

Amaphrojekthi ezohwebo asebenzisa izinhlelo ezithuthukisiwe ze-admixture abonisa ukuncishiswa kokusetshenziswa kukasamente ngo-5–20% ngenkathi egcina noma ethuthukisa amandla nokuqina. Ama-admixture okungenisa umoya anwebe impilo yesevisi ezindaweni ezibandayo futhi anciphise imijikelezo yokugcinwa. I-shrinkage reducing admixture yehlise ukuqhekeka kwasekuqaleni ezintweni ezincane zesakhiwo namaphaneli angaphandle, yehlisa izindleko zokulungisa. I-Dezhou Zhongke New Materials Co., Ltd. izihlukanisa ngesevisi yezobuchwepheshe yendawo, uhla olubanzi lwemikhiqizo oluhlanganisa ama-water-reducers, ama-concrete retarders, kanye ne-shrinkage reducing admixture, kanye nokuzibophezela ekushicileleni idatha yokusebenza. Lezi zinzuzo zenza i-Dezhou Zhongke ibe umphakeli onokuncintisana namabhizinisi ahlose ukuhlanganisa ukonga izindleko nokusimama.

Izithako ezingezekayo ziyithuluzi elinamandla lokunciphisa ikhabhoni egxilile, ukuthuthukisa ukuqina, nokuthuthukisa ukwakhiwa emaphrojekthi esimanjemanje. Ngokuhlanganisa izinciphisi zamanzi, ama-ejenti okungenisa umoya, izithako ezinciphisa ukuncipha, kanye nezinciphisi noma izikhawulezisi ezenziwe ngendlela oyifisayo kumiklamo yokuxuba, abakhi bangafinyelela ukusebenza okuphezulu ngomthelela omncane kwezemvelo. Ukukala imiphumela nge-EPDs nokunamathela ezindleleni ezingcono kakhulu ekuhloleni nasekulawuleni ikhwalithi kuqinisekisa ukuthi izimangalo zokusimama ziyiqiniso. Izinkampani ezifana neDezhou Zhongke New Materials Co., Ltd. zinikeza ubuchwepheshe obudingekayo kanye nohlu lwemikhiqizo oludingekayo ukuze lezi zinguquko ziphumelele kubakhiqizi, ososizindaba, nabacacisi.

Ukuze uthole izixazululo ezenziwe ngendlela efanele, ukubonisana kwezobuchwepheshe, kanye nedatha yomkhiqizo okubandakanya ukwesekwa kwe-EPD, thintana neDezhou Zhongke New Materials Co., Ltd. Ithimba labo lingakusiza ngokuthuthukisa ingxube, ukuhlolwa okusebenzayo, kanye nemibhalo ukuze uhlangabezane nemigomo yokusimama yeprojekthi. Funda kabanzi mayelana nokunikezwa komkhiqizo kanye nezinsiza zokweseka ku-IMIKHIQIZO ikhasi noma uxhumane nge- Ukusekelwa ikhasi ukuze uqale ukubambisana okugxile ezixazululweni ze-concrete ezihlala isikhathi eside, ezingenawo amacarbon.
