(Ukuxuba Usimende Negwebu Ngezicelo Ezingasindi)

Uke uzibuze ukuthi osonkontileka bawenza kanjani ukhonkolo oqinile kodwa olula ngendlela emangalisayo? Akuwona umlingo. Kuwucwaningo lwesayensi. Ikakhulukazi, kuhlanganisa ukuhlanganisa usimende ovamile ngegwebu. Lokhu kuthuthukisa impahla ekhethekile ebizwa ngokuthi ukhonkolo onegwebu noma usimende ongasindi. Lezi zinto ziguqula igeyimu yevidiyo ekwakheni nasekwakhiweni. Inikeza amandla ngaphandle kwesisindo esindayo esijwayelekile. Ake singene kokuthi konke lokhu kumayelana nani.

1. Yini i-Lightweight Cement? .

Usimende ongasindi akuwona nje ukhonkolo ojwayelekile owenziwe waba mncane. Kungumkhiqizo okhethekile. Siyithuthukisa ngokwethula umoya ube yingxube kasimende. Kanjani ngempela? Sifaka igwebu. Leligwebu lenziwa ngokuhlanganisa umoya, amanzi, kanye nommeleli we-lathering oyingqayizivele. Kucabange njengensipho, nokho yakhelwe ukwakha. Ngemuva kwalokho sixuba leli gwebu kakhulu nge-slurry yekhonkrithi. I-slurry ingusimende, amanzi, futhi ngezinye izikhathi ezinye izinto ezifana nesihlabathi noma umlotha wempukane.

Umphumela? Ingxube elayishwe amabhamuza omoya amancane amaningi. Lawa mabhamuza asakazwa ngokulinganayo kulo lonke unamathisele ukhonkolo. Babhajwa njengamasethi kakhonkolo. Lo moya ovalelekile wenza umkhiqizo wokugcina ube lula kakhulu kunokhonkolo ovamile. Inani legwebu esilifakayo lilawula ukuminyana. Igwebu elengeziwe libonisa ukhonkolo olula. Igwebu elincane kakhulu lenza kube nzima kakhulu kodwa kube namandla kakhulu. Singayilungisela umsebenzi odingekayo.

Lo simende ongasindi namanje usasebenza njengokhonkolo. Iyasetha futhi ihlele nesikhathi. Ithola amandla. Nokho ibheka kancane kakhulu. Izwakala ngempela njengetshe le-pumice. Inembobo ngenxa yawo wonke lawo maphakethe omoya. Le porosity iyinikeza izindawo zokuhlala ezikhethekile noma ezentengiselwano esedlule nje ukukhanya. Sizobandakanyeka kulezo zinzuzo ezilandelayo.

2. Kungani Kufanele Usebenzise Ukhonkolo Onegwebu? .

Kungani uzihlupha ukufaka igwebu? Kubonakala kungasebenzi. Akudingeki ukuthi ukhonkolo ube namandla? Empeleni, lawo mabhamuza omoya aletha izinzuzo ezinkulu. Inzuzo enkulu iyabonakala: isisindo sehlisiwe. Lokhu kwenza ukuphatha, ukuletha, nokubeka umkhiqizo kalula kakhulu. Abasebenzi bangathutha amabhulokhi amakhulu noma amaphaneli ngaphandle kwemishini esindayo. Lokhu konga imali nesikhathi kuwebhusayithi.

Isisindo esilula ngokufanayo siphakamisa umthwalo omncane kumafreyimu. Bona ngeso lengqondo uthuthukisa i-flooring eyengeziwe esakhiweni esikhona. Ukusebenzisa ukhonkolo ovamile kungase kugcwalise phansi phansi. Ukhonkolo ofakwe amagwebu uyinkonzo ehlakaniphile. Yengeza isisindo esengeziwe esilinganiselwe. Izisekelo zingaba ngosayizi omncane futhi zingabizi futhi. Isakhiwo sonke sinesisindo esincane.

Lawo maphakethe omoya alingisa ukugquma. Babamba umoya, ukunciphisa ukudluliswa okufudumele. Lokhu kusho ukuthi izindawo zodonga ezenziwe ngosimende ongasindi zigcina ukushisa phakathi nobusika nangaphandle ehlobo. Ithuthukisa ukusebenza kwamandla. Osonkontileka abakhayo bavamise ukusisebenzisa ezindaweni zodonga, flooring, nezinhlelo zokufulela ngenxa yalokhu. Ungadinga i-insulation encane eyengeziwe.

Izinto ezisetshenziswayo nazo ziyasebenza ngempela uma kuswakeme. Ihamba kalula ibe yizimo eziyinkimbinkimbi nasezindaweni okunzima ukufinyelela kuzo. Ivala izikhala ngokuphelele ngaphandle kokudinga ukudlidliza. Lokhu kuhle kakhulu ekubuyiseleni imisele noma ukugcwalisa amapayipi amadala. Futhi okunye, akushi. Isisekelo sikakhonkolo siyayivikela. Umoya ovalelwe awuncibiliki. Inikeza ukuvikeleka okuhle komlilo. Ngokunjalo iqinile futhi ngeke ibole noma idwebe izinambuzane njengamathini ogodo. Kuyinto esebenzayo.

3. Wenziwa Kanjani Ukhonkolo Ongasindi? .

Ukwenza ukhonkolo onegwebu kuhlanganisa nezinyathelo ezithile. Ekuqaleni, silungisa udaka lukakhonkolo. Lokhu kuvame ukuhlanganisa ukhonkolo wasePortland, amanzi, futhi kwezinye izimo isihlabathi esihle noma umlotha wempukane. I-Fly ash iwumkhiqizo ovela esikhungweni samandla enuzi wamalahle. Ingenza ingxube ibe namandla futhi ibe luhlaza kakhulu. Sixuba lezi zingxenye ezomile ngokuphelele ngamanzi ukuze senze ubushelelezi, unamathisele uketshezi.

Ngokuhlukana, sikhiqiza igwebu. Umshini okhethekile obizwa ngokuthi i-foam generator wenza lokhu. Sihlanganisa amanzi nge-lathering agent. Lo menzeli uyi-surfactant, efana nensipho. Ijeneretha iphampa le ngxube ngomoya ocindezelweyo. Lokhu kwakha isitebele, ukushefa-ukhilimu-njengegwebu. Ikhwalithi ephezulu yommeleli we-foam ibalulekile. Igwebu elihle lithuthukisa umfaniswano, amabhamuza aqinile angeke adilike kalula.

Okulandelayo off, sihlanganisa i-foam ne-slurry yekhonkrithi. Lokhu kwenzeka kudivayisi yokuxuba. Sifaka i-foam ngokuqhubekayo. Silawula inani ngokuqondile. Igwebu elidlulele lenza ingxube ibe buthaka. Ukunganeli akukwenzi kukhanye ngokwanele. Siwahlanganisa kahle kodwa kakhulu. Sifuna amabhamuza egwebu asabalaliswe ngokufanayo kulo lonke udaka ngaphandle kokuwaphula.

Ekugcineni, sithela ingxube enegwebu ibe yisikhunta kanye nesikhutha noma ngqo lapho idingeka khona. Ngenxa yokuthi iwuketshezi, igeleza ngokushesha futhi i-degree ngokwayo. Asidingi amathuluzi omsindo osindayo njengokhonkolo ojwayelekile. Ngemuva kwalokho isungula futhi iqine njengokhonkolo ojwayelekile. Ngemuva kokuhlinzwa, ifika iqine kodwa ingasindi. Ukuminyana kuncike enanini legwebu elifakiwe ngesikhathi sokuhlanganisa. Singakwenza kube lula kakhulu noma kube nzima kakhulu.

4. Usetshenziswa kuphi Ukhonkolo Ongasindi? .

Ukusetshenziswa kokhonkolo onegwebu kukhula ngokushesha. Izakhiwo zayo zokuhlala ezihlukile zixazulula izinkinga ezimbalwa zokwakha nezokwakha. Indawo eyodwa ebalulekile amabhulokhi wokwakha namaphaneli. Izimboni ze-Precast zenza amabhulokhi anesisindo esincane. Lawa mabhulokhi alula kakhulu ukuthi abamashi bawanakekele. Basheshisa ukwakheka kodonga futhi banciphise izindleko zabasebenzi. Baphinde bathuthukise ukungezwani komzimba ezindlini nasezindaweni zokusebenza.

Okunye ukusetshenziswa okubalulekile ku-floor screeds. I-screed iyisendlalelo ngaphezu kwe-flooring slab kakhonkolo. Inikeza isiphetho esibushelelezi sokhaphethi, amathayili e-ceramic, noma ukhuni. Izinsalela zesanti zesihlabathi zendabuko zikhulu. Ama-screed okhonkolo anegwebu alula. Babeka ingcindezi encane kakhulu kuhlaka. Zoma ngokushesha okukhulu. Bangeza ukufakwa kwe-thermal nokulalelwayo futhi. Lokhu kudumile emafulethini.

Ihlukile ekugcwalisweni okungenalutho. Kudingeka ukulayisha isiqukathi esidala esingaphansi komhlaba? Noma gcina iphaseji yemayini engenamuntu? Noma pakisha inhlabathi ezungeze amapayipi emseleni? Ukumpompa ukhonkolo onesisindo esilula kulungile. Ihamba ngqo kuzo zonke izindawo. Kuqina ukunikeza usizo ngaphandle kwesisindo esiningi. Izinkampani zamandla kanye nonjiniyela bomphakathi bayisebenzisela le nhloso.

Izicelo zokumboza uphahla ziyanqoba. Siwusebenzisela ukukhiqiza imithambeka ethambile ezinhlelweni zokufulela eziyisicaba zokudonsa amanzi. Kuyakhanya, ngakho-ke ayilayishi kakhulu isakhiwo sokumboza uphahla. Ivikela kahle. Iyakwazi ukumelana nomlilo. Amalunga ebhuloho kanye ne-embankments inzuzo nayo. Isisindo esincishisiwe sisiza ukugwema ukuxoxisana okuphansi. Abaklami bendawo baze bayisebenzisele izici zegceke ezingasindi noma ukwakheka kwamatshe okwenziwa.
