Indaba engemuva kokhonkolo wesikhathi sasemkhathini nokuthi inganciphisa kanjani isisindo sikakhonkolo wangaphambili ngenkathi ikhiqiza imikhiqizo yamandla aphezulu.
Lona umqondo olula, kodwa impendulo ayilula: ukunciphisa isisindo sokhonkolo ngaphandle kokuthinta amandla ayo. Masiqhubeke sixabanise isici ngenkathi sixazulula izinkinga zemvelo; akugcini nje ukunciphisa i-carbon ohlelweni lokukhiqiza, kodwa futhi unciphise udoti owulahla eceleni komgwaqo.
"Lokhu kube yingozi enkulu," kusho u-Bart Rockett, umnikazi wokhonkolo ophucuziwe wase-Philadelphia kanye nezigqoko zengilazi ze-Rockett. Waqale wazama ukuthuthukisa uhlelo lwakhe lokumboza lukakhonkolo olupholishiwe, iphansi elisebenzisa u-100% izingcezwana zengilazi ezigaywe kabusha zangemuva komthengi ukuze akhe umphumela we-terrazzo. Ngokwemibiko, ishibhile ngo-30% futhi inikeza iwaranti yeminyaka engu-20 yesikhathi eside. Uhlelo ludizayinelwe ukuthi lupholishwe kakhulu futhi lubize amadola angu-8 ngonyawo olungaphansi kwe-terrazzo evamile, okungenzeka konge usonkontileka opholisha imali eningi kuyilapho ekhiqiza izitezi zekhwalithi ephezulu.
Ngaphambi kokupholisha, u-Rockett waqala isipiliyoni sakhe sokukhonkolo ngeminyaka engama-25 yokhonkolo wokwakha. Ingilazi “eluhlaza” egaywe kabusha yamdonsela embonini kakhonkolo ophucuziwe, kwase kuba ukumbozwa kwengilazi. Ngemva kwamashumi eminyaka esipiliyoni, imisebenzi yakhe kakhonkolo epholishiwe isizuze imiklomelo eminingi (ngo-2016, wawina i-“Reader's Choice Award” ye-Concrete World kanye neminye imiklomelo engama-22 eminyakeni edlule-kuze kube manje), inhloso yakhe wukuthatha umhlalaphansi. Ziningi izinhlelo ezihlelwe kahle.
Ngesikhathi epaka ukuze afake uphethiloli, u-Archie Filshill wabona iloli lika-Rockett, wayesebenzisa ingilazi egaywe kabusha. Ngokwazi kwakhe uPhil Hill, uyena yedwa owenza noma yini ngezinto zokwakha. UFilshill uyi-CEO kanye nomsunguli we-AeroAggregates, umkhiqizi we-ultra-light closed-cell foam glass aggregates (FGA). Izithando zomlilo zenkampani zisebenzisa ingilazi egaywe kabusha yangemuva kwe-post-consumer engu-100%, njengephansi le-Rockett's Glass Overlay, kodwa izilinganiso zokwakha ezikhiqizwayo zilula, azishi, azigqugquzeli, azikhipha amanzi mahhala, azimubi, azikwazi ukumelana namakhemikhali, ukubola nama-asidi. Lokhu kwenza i-FGA ibe enye indlela enhle kakhulu yamabhilidi, amaphethelo angasindi, amapulatifomu okusabalalisa imithwalo kanye nama-subgrades angaphansi, kanye nokunciphisa imithwalo esemaceleni ngemuva kwezindonga ezibambayo nezakhiwo.
Ngo-Okthoba 2020, “Weza kimi wafuna ukwazi ukuthi ngenzani,” kusho uRockett. Wathi, 'Uma ungafaka lawa matshe (iqoqo lakhe) kukhonkolo, uzoba nokuthile okukhethekile.'
I-AeroAggregates inomlando cishe weminyaka engama-30 e-Europe kanye neminyaka eyi-8 e-United States. Ngokusho kuka-Rockett, ukuhlanganisa isisindo esingasindi se-foam aggregate esekwe engilazini nosimende bekulokhu kuyinkinga ngaphandle kwesixazululo.
Ngesikhathi esifanayo, u-Rockett usebenzise usimende omhlophe e-csa esitezi sakhe ukuze aqinisekise ukuthi iphansi lakhe lithola ikhwalithi yobuhle nokusebenza ayifunayo. Wayenelukuluku lokwazi ukuthi kuzokwenzekani, wahlanganisa lesi simende ne-lightweight aggregate. Uma sengifake usimende, [isamba] sizontanta siye phezulu,” kusho uRockett. Uma othile ezama ukuhlanganisa inqwaba kakhonkolo, akukhona lokho kanye okufunayo. Noma kunjalo, ilukuluku lakhe lamshukumisela ukuba aqhubeke.
I-Csa Cement yavela enkampanini ebizwa ngokuthi iCaltra, eseNetherlands. Omunye wabasabalalisi abasebenzisa i-Rockett yi-Delta Performance, egxile ekuxubeni, ukufaka imibala kanye nemiphumela ekhethekile kasimende. UShawn Hays, umnikazi nomongameli weDelta Performance, wachaza ukuthi nakuba ukhonkolo ovamile umpunga, izinga elimhlophe kusimende livumela osonkontileka ukuba bafake imibala cishe kunoma yimuphi umbala—ikhono eliyingqayizivele lapho umbala ubalulekile. .
“Ngibheke ngabomvu ukusebenza noJoe Ginsberg (umklami owaziwayo waseNew York naye owabambisana noRockett) ukuze aqhamuke nento ehluke kakhulu,” kusho uHayes.
Enye inzuzo yokusebenzisa i-csa ukusebenzisa i-carbon footprint encishisiwe. "Eqinisweni, usimende we-csa uwusimende osebenza ngokushesha, othatha indawo kasimende wasePortland," kusho uHayes. "Usimende we-csa ohlelweni lokukhiqiza uyafana ne-Portland, kodwa empeleni uyasha ngezinga lokushisa eliphansi, ngakho-ke ubhekwa-noma uthengiswa njengosimende ongavumelani nemvelo."
Kule minyaka yesikhala i-ConcreteGreen Global Concrete Technologies, ungabona ingilazi negwebu kuxutshwe kukhonkolo.
Esebenzisa inqubo enelungelo lobunikazi, yena kanye nenethiwekhi encane yochwepheshe bemboni bakhiqiza i-block prototype lapho imicu yakha umphumela we-gabion, imisa i-aggregate kukhonkolo esikhundleni sokuntanta phezulu. “Lena yiHoly Grail osekuphele iminyaka engu-30 wonke umuntu ewufuna,” usho kanje.
Eyaziwa ngokuthi ukhonkolo wesikhathi sasemkhathini, wenziwa imikhiqizo eyenziwe ngaphambilini. Kuqiniswe izinsimbi zensimbi eziqiniswe ngengilazi, ezilula kakhulu kunensimbi (ingasaphathwa eyokuthi ziqine ngokuphindwe kahlanu), amaphaneli kakhonkolo abikwa ukuthi alula ngo-50% kunokhonkolo wendabuko futhi ahlinzeka ngedatha yamandla ehlaba umxhwele.
“Lapho sonke sesiqedile ukuxuba i-cocktail yethu ekhethekile, sinesisindo esingamakhilogremu angu-90. Uma kuqhathaniswa nokhonkolo ojwayelekile ongu-150 i-cubic foot ngayinye,” kuchaza uRockett. “Akuncishiswa kuphela isisindo sikakhonkolo, kodwa manje nesisindo sesakhiwo sakho sonke sizoncipha kakhulu. Asizange sizame ukuthuthukisa lokhu. Ukuhlala egaraji lami ngoMgqibelo ebusuku, kwakuyinhlanhla nje. Nginosimende owengeziwe futhi angifuni ukuwumosha. Kwaqala kanjalo-ke. Ukube angizange ngithinte ukhonkolo ophucuziwe eminyakeni engu-12 edlule, ubungeke uguquke ube yisimiso saphansi, futhi ubungeke uguquke ube usimende ongasindi.”
Ngemva kwenyanga, iGreen Global Concrete Technology Company (GGCT) yasungulwa, ehlanganisa ozakwethu abambalwa abathile ababone amandla emikhiqizo emisha ye-Rockett.
Isisindo: 2,400 amakhilogremu. Ukhonkolo weminyaka yesikhala egcekeni ngalinye (ukhonkolo ojwayelekile unesisindo esingamakhilogremu angu-4,050 egcekeni ngalinye)
Ukuhlolwa kwe-PSI kwenziwa ngoJanuwari 2021 (idatha yokuhlola ye-PSI entsha yamukelwe ngoMashi 8, 2021). Ngokuka-Rockett, ukhonkolo weminyaka yesikhala ngeke uqhekeke njengoba umuntu ebengalindela ekuhlolweni kwamandla acindezelayo. Kunalokho, ngenxa yobuningi bemicu esetshenziswa kukhonkolo, iye yanda kunokuba igundwe njengokhonkolo wendabuko.
Wakha izinguqulo ezimbili ezihlukene zokhonkolo wesikhathi sasemkhathini: inhlanganisela yengqalasizinda yokumpunga okujwayelekile okukhonkolo kanye nengxube yezakhiwo emhlophe yokufaka imibala nokuklama. Uhlelo lwephrojekthi "yobufakazi bomqondo" seluyakhiwa. Umsebenzi wokuqala wawuhlanganisa ukwakhiwa kwesakhiwo sokubonisa esinezitezi ezintathu, esasihlanganisa indawo engaphansi nophahla, amabhuloho abantu abahamba ngezinyawo, izindonga ezingazwakali msindo, amakhaya/izindawo zokukhosela zabangenamakhaya, amakholvethi, njll.
Isihloko se-GGCT siklanywe ngu-Joe Ginsberg. I-Ginsberg ikleliswe endaweni yama-39 phakathi Kwabaklami Bomhlaba Abaphezulu Abayi-100 nge-Inspiration Magazine kanye nabaklami abangcono kakhulu abangama-25 bangaphakathi eNew York nge-Covet House Magazine. UGinsberg uthinte uRockett ngenkathi ebuyisela indawo yokwamukela izivakashi ngenxa yesitezi sakhe esimbozwe ngengilazi.
Njengamanje, uhlelo ukwenza yonke imiklamo yephrojekthi yesikhathi esizayo igxile emehlweni kaGinsberg. Okungenani ekuqaleni, yena nethimba lakhe bahlela ukugada futhi bahole amaphrojekthi anemikhiqizo kakhonkolo ye-precast yeminyaka yobudala ukuze kuqinisekiswe ukuthi ukufakwa kulungile futhi kuhlangabezana nezindinganiso.
Umsebenzi wokusebenzisa ukhonkolo weminyaka yesikhala usuqalile kakade. Ngethemba lokuthi izogqashuka ngo-Agasti, i-Ginsberg iklama indawo engu-2,000 square foot. Isakhiwo sehhovisi: izitezi ezintathu, izinga elilodwa elingaphansi, phezulu kophahla. Isitezi ngasinye singamamitha-skwele angama-500. Konke kuzokwenziwa esakhiweni, futhi yonke imininingwane izokwakhiwa kusetshenziswa idizayini yephothifoliyo yezakhiwo ye-GGCT, i-Rockett Glass Overlay ne-Ginsberg.
Umdwebo wendawo yokukhosela abantu abangenakhaya/indlu eyakhiwe ngama-slabs kakhonkolo angasindi ngaphambili. Ubuchwepheshe bokhonkolo bomhlaba obuhlaza
U-Dave Montoya ka-ClifRock kanye no-Lurncrete basebenzisana ne-GGCT ukuze baklame futhi bakhe iphrojekthi yezindlu eyakhiwa ngokushesha yabantu abangenamakhaya. Eminyakeni yakhe engaphezu kwe-25 embonini yekhonkrithi, uye wasungula uhlelo olungachazwa kangcono ngokuthi "udonga olungabonakali". Ngendlela eyenziwe lula kakhulu, ingxube yokunciphisa amanzi ingangezwa ku-grouting ukuvumela usonkontileka ukuthi asukume ngaphandle kwe-formwork. Usonkontileka uyobe esekwazi ukwakha u-6-foot. Khona-ke udonga "luqoshwe" ukuhlobisa umklamo.
Ubuye abe nolwazi lokusebenzisa imigoqo yensimbi eqiniswe nge-glass fibre kumaphaneli okuhlobisa kanye nomsebenzi wokuhlala ukhonkolo. U-Rockett wamthola maduzane, enethemba lokuqhubekisela phambili i-Space Age Concrete.
Njengoba i-Montoya ijoyina i-GGCT, ithimba lasheshe lathola indlela entsha nenjongo yamaphaneli abo akhiwe ngaphambili angasindi: ukuhlinzeka ngezindlu zokukhosela kanye nemizi engomahambanendlwana yabangenamakhaya. Ngokuvamile, izindawo zokukhosela zendabuko eziningi zicekelwa phansi izenzo zobugebengu njengokukhumula ithusi noma ukushiswa kwempahla. “Ngesikhathi ngiwenza ngokhonkolo,” kusho uMontoya, “inkinga ukuthi abakwazi ukuwuphula. Abakwazi ukuphambana nakho. Ngeke bakulimaze.” Lawa maphaneli awakwazi ukumelana nesikhutha, amelana nomlilo, futhi ahlinzeka ngenani lemvelo elingu-R (noma Ukufakwa Kwamanzi) ukuze kunikeze ukuvikeleka kwemvelo okwengeziwe.
Ngokwemibiko, izindawo zokukhosela ezisebenza ngama-solar panel zingakhiwa ngosuku olulodwa. Izinsiza ezifana nezintambo namapayipi zizohlanganiswa kumaphaneli kakhonkolo ukuvimbela umonakalo.
Okokugcina, izakhiwo ezingomahambanendlwana zenzelwe ukuthi zithwaleke futhi zifane, okungahle konge omasipala imali eningi uma kuqhathaniswa nezakhiwo ezingasimami. Nakuba i-modular, umklamo wamanje wendawo yokukhosela ingamamitha angu-8 x 10. (Noma cishe amamitha-skwele angama-84) yendawo yaphansi. I-GGCT ixhumana nohulumeni abathile bezifundazwe nabasekhaya ezindaweni ezikhethekile zezakhiwo. I-Las Vegas ne-Louisiana isivele ibonise isithakazelo.
U-Montoya usebenzisane nenye inkampani yakhe, i-Equip-Core, namasosha ukuze asebenzise uhlelo olufanayo olusekelwe kumaphaneli kwezinye izakhiwo zokuqeqesha ngobuhlakani. Ukhonkolo uqinile futhi uqinile, futhi izimbobo zokudutshulwa ezibukhoma zingacutshungulwa ngesandla ngokuxuba ukhonkolo ofanayo. Isiqephu esilungisiwe sizolapheka phakathi kwemizuzu eyi-15 kuya kwengama-20.
I-GGCT isebenzisa amandla okhonkolo weminyaka yesikhala ngesisindo sayo esilula namandla. Bagxila kakhulu ekufakeni ukhonkolo owenziwe ngaphambili ezakhiweni nezakhiweni ngaphandle kwezindawo zokukhosela. Imikhiqizo engase ibe khona ihlanganisa izindonga zethrafikhi ezingazwakali kalula, izitebhisi, namabhuloho abahamba ngezinyawo. Bakha iphaneli yokulingisa izindonga ezingama-4 ft x 8 ft, umklamo ubukeka njengodonga lwamatshe. Uhlelo luzohlinzeka ngemiklamo emihlanu ehlukene.
Ekuhlaziyeni kokugcina, umgomo wethimba le-GGCT uwukuthuthukisa amakhono kasonkontileka ngohlelo lokunikeza amalayisense. Ngokwezinga elithile, isabalalise emhlabeni futhi idale amathuba emisebenzi. “Sifuna abantu bajoyine futhi bathenge amalayisensi ethu,” kusho uRockett. “Umsebenzi wethu ukuthuthukisa lezi zinto ukuze sikwazi ukuzisebenzisa ngokushesha… Siya kubantu abangcono kakhulu emhlabeni, esikwenzayo manje. Abantu abafuna ukuqala ukwakha izimboni, bafuna ukwenza imiklamo yabo Abantu ababambe iqhaza eqenjini… Sifuna ukwakha ingqalasizinda eluhlaza, sinengqalasizinda eluhlaza. Sidinga abantu abazokwakha ingqalasizinda eluhlaza manje. Sizoyithuthukisa, sizobakhombisa ukuthi kwakhiwa kanjani ngezinto zethu, bazokwamukela.
"Ukucwila kwengqalasizinda kazwelonke manje sekuyinkinga enkulu," kusho uRockett. “Ukuvuza okukhulu, izinto ezineminyaka engu-50 kuya ku-60 ubudala, ukucwila, ukuqhekeka, ukukhuluphala, nendlela ongakha ngayo izakhiwo ngale ndlela futhi wonge izigidigidi zamarandi ukusebenzisa izinto ezingasindi, uma unezi-20,000. imoto bese ugijima kuyo usuku lonke [ebhekisela kumandla okusebenzisa ukhonkolo weminyaka yesikhala ekwakhiweni kwebhuloho]. Kuze kube yilapho ngiqala ukusebenzisa i-AeroAggregates futhi ngilalela lokho abakwenzayo kuzo zonke izingqalasizinda kanye ne-lightweight yayo Ngaphambili, ngaqaphela ngempela konke lokhu. Imayelana nokuqhubekela phambili. Yisebenzise ukwakha.”
Uma ucabangela izingxenye zekhonkrithi yeminyaka yesikhala ndawonye, ikhabhoni nayo izokwehla. I-csa Cement ine-carbon footprint encane, idinga izinga lokushisa eliphansi lesithando somlilo, isebenzisa igwebu nezinhlanganisela zengilazi ezigaywe kabusha, kanye namabha ensimbi aqiniswe ngefayibha yengilazi-ngamunye wawo odlala indima engxenyeni “eluhlaza” ye-GGCT.
Isibonelo, ngenxa yesisindo esilula se-AeroAggregate, osonkontileka bangathutha amayadi angu-100 wento ngesikhathi, uma kuqhathaniswa namayadi angu-20 elolini elivamile lama-asi amathathu. Kusukela kulo mbono, iphrojekthi yakamuva esebenzisa isikhumulo sezindiza i-AeroAggregate njengesamba isindise usonkontileka cishe uhambo oluyizi-6,000.
Ngaphezu kokusiza ukubuyisela ingqalasizinda yethu, i-Rockett iphinde ibe nomthelela ekuzinzeni ngezinhlelo zokugaywa kabusha. Komasipala nezikhungo zokugaywa kabusha, ukususa ingilazi egaywe kabusha kuyinselelo ebizayo. Umbono wakhe ubizwa ngokuthi “owesibili ngobukhulu obuluhlaza okwesibhakabhaka” futhi uyingilazi eqoqwe ekuthengeni kukamasipala nasemalokishini. Lo mqondo uvela ekunikezeni injongo ecacile yokugaywa kabusha-ukuvumela abantu ukuthi baqonde kangcono umphumela wokugcina wokugaya kabusha endaweni yabo. Uhlelo luwukwenza ibhokisi elihlukile lokugcina elikhulu (isitsha sesibili esiluhlaza okwesibhakabhaka) sokuqoqwa kwengilazi ezingeni likamasipala, kunodoti ongawubeka eceleni komgwaqo.
I-GGCT iyasungulwa ku-AeroAggregate complex e-Eddystone, e-Pennsylvania. IGreen Global Concrete Technologies
“Manje, wonke udoti ungcolile,” esho. “Uma singahlukanisa ingilazi, izokonga abathengi izigidi zamarandi ezindlekweni zokwakhiwa kwengqalasizinda kazwelonke, ngoba imali elondoloziwe ingabuyiselwa kuziphathimandla zikamasipala. Sinomkhiqizo ongaphonsa ingilazi oyilahla emgqonyeni kadoti emgwaqeni , Isitezi sesikole, ibhuloho noma amatshe ngaphansi kwe-I-95… Okungenani uyazi ukuthi uma ulahla okuthile, kufeza injongo. Lesi isinyathelo sokuqala.
