Ukuthuthukisa uhlobo olusha lwezinto zokwakha ezisindisa amandla, ezonga umhlaba, nezihlolayo ukuze zishintshe amabhulokho amatshe aqinile ayesetshenziswa kakhulu, kukhona uhla lwemigomo emisha olwaqalelekela yizwe. Idolobha eliseqenjini eliqondile kanye namadolobha amakhulu naphakathi kwezinyathelo ezisemathafeni azokuvimbela ukusebenzisa amabhulokho amatshe aqinile ukuze kuthuthukiswe ubuchwepheshe bezindlu futhi kuthuthukiswe izinga lokuhlala.

Izingcezu zekhonkrithi ezizimele ziye zaba yinto edumele emkhulu emkhakheni ngenxa yezimpawu zazo ezizimele zokulondoloza umhlaba, ukuvikela imvelo, ukusindisa amandla kanye nokugqunywa kabusha, futhi zisungulwa ngamanyuvesi ezombangazwe ezihambelana nazo, okuyenza ibe yimboni entsha enemisebenzi engapheliyo.

I-concrete ethunzini iyisicelo sokwakha izindonga futhi inekhono elihle lokufudumeza, ingahlangabezana nezidingo zokonga amandla ngaphandle kokwengeza ezinye izinto. Uma iqhathaniswa nezinto ezisetshenziswa kabanzi zokufudumeza, njenge-EPS thermal insulation mortar kanye ne-foam polystyrene panel evamile, i-aerated concrete inezinzuzo ezilandelayo, ikh quality, kulula ukuyisebenzisa, impilo ende, ukusebenza kahle kwezindleko, njll.
Izingcezu zekhonkrithi ezinamoya zibhekisela kumkhiqizo oqinekezelwe ngamanzi, onamatshe amancane, wesilicate, owenziwe ngokusebenzisa izinto eziyisilika (umhlabathi, umlotha wemalahle kanye nezimpahla eziminyene ezinesilika) kanye nezinto ezinkanyezi (ilayisi nekonkrithi) njengezinto ezibalulekile, futhi zihlanganiswe nomkhiqizo wokukhuluhluza (u-aluminium powder) ngemuva kokudibanisa, ukuxuba, ukugcwala, ukuqeqeshwa kwangaphambili, ukukhipha izinto, ukucindezela ngamanzi kanye nokulondolozwa. Ngoba inezinso eziningi, ezineminyaka efana kanye nezinto ezimncane ngemuva kokuhlahlulwa, ibizwa ngokuthi izingcezu zekhonkrithi ezinamoya.

Ikhonkrithi ezinamoya ye-Lime-Coal ash
-
I-Lime – isihlabathi – icementi i-aerated concrete
-
Isilimo – uhlwanyelo olukhulu lwesihlabathi – iconcreti emenyezelwe ngesihlabathi.
Izinto zokwakha zekhonkrithi eyi-aerated zingabhangwa zibe yizinhlobo ezine: isisekelo, isithuthukisi, isilungiselelo nesakhiwo. Phakathi kwazo, isisekelo, isithuthukisi kanye nesilungiselelo zidinga ukulinganisa okukhulu, ngakho-ke ngokuvamile zidinga ukushicilelwa, njengokuthi:
-
Isitshalo
180-200 amakhasi
D90-D85
(izinsimbi ezikhulu azivunyelwe) -
Ntshuku yesihlangu
325 amakhasi
D55-D70
(180 amakhasi, D75-D85) -
I-aluminium paste
200 amakhasi
D97
Bheka umthetho JC / T621, JC / T409, JC T407 / njll.
Iphutha elisheshayo le-lime: I-lime elishesayo ngemva kokushisa kufanele iluliwe ngesixhumi sokuqhekeza se-jaw, bese liya ebhukini lokuqongelela nge-elevator. Ngemva kwalokho, izinto zebhodlela ebhukini lokuqongelela ziyokhonjiswa emlilweni wokugaya we-Euro-type grinding mill nge-vibrating feeder. Ngemva kokugaya emlilweni wokugaya nangokwahlukaniswa yi-classifier, iphutha lizoqoqwa ekukhothweni kwezinto ezibhabile. Ekugcineni, iphutha eliqoqweyo lizoqhubeka liya ethangeni lokugcina izinto zokwakha ze-aerated concrete nge-elevator noma isixhumi sokudlulisela i-pneumatic. (Indlela yokulungiselela iphutha njenge-coal)
Iphuthuma imphlophele ye-layim, kunokuba ilayim ehambiswe, ivame ukusetshenziswa ukwenza isimenga esigcwele umoya. Ngenxa yalokho, lapho iphuthuma imphlophele ye-layim isetshenziswa, inani elikhulu lokushisa lizoveliswa, okuzoqhubekisela phambili ukwakhiwa kwe-gel ehambiswe. Ngaleso sikhathi, inqubo yokwenza impahla ingalawulwa futhi ukusebenza kwempahla kungalungiswa.
Izinto zokwakha isikali se-aerated concrete, njengecementi, i-gypsum, itshe lama-lime, umlotha wamagciwane noma isihlahla, zizohlinzwa noma zicwangciswe, zibhoshwe futhi zihlelwe emahhovisi okugcina ahlukene; kamuva ziyokwela esakhiweni sokuxuba ukuze zixutshwe futhi zixutywe nezinto ezungeze njengephunga lamanti nemanzi ngemva kokulinganisa. Ngemva kokuxuba, zizokwela esakhiweni esingumoya ukuze ziqhame futhi zizame. Ukucutshwa kuzokwenziwa ngokuya ngemfuno yokukhiqiza. Ngemva kokugqama kwamagama, kuzobekwa e-reactor yokushisa ngamanzi ukuze kube ne-autoclaved curing bese kukhishwa.
