Ukukhethwa kwama-comscrete admixtures:
(1) Umenzeli we-ejenti osebenza kahle futhi ophakeme futhi ophakeme Ukuze ukhonkolo ngezidingo ezikhethekile zamandla kusenesikhathi, sebenzisa usimende osheshe ukusetha noma engeza i-silica fuume; Lapho usebenzisa i-Silica Fume ngokhonkolo edinga ukumelana kokugqoka, futhi lapho ukhonkolo omkhulu ukhonza ukhonkolo kudinga ukunciphisa ukushisa kwe-hydration, inani le-silica fuume noma umlotha we-fly kumele angezwe. Isikhathi sokuqala sokusetha ukhonkolo esixutshwe ne-ejenti yokunciphisa amanzi ephezulu isikhathi eside kunekhonkolo ejwayelekile. Lapho likhulu inani, isikhathi eside isikhathi sokuqala sokusetha.
. Faka inani elithile lokuqukethwe komoya ukuze ukhonkolo, futhi uma okuqukethwe komoya kukhuphuka ngo-1%, amandla azokwehla cishe ngo-5%. Ngakho-ke, lapho ulungiselela ukhonkolo wamabanga aphezulu, okuqukethwe komoya kufanele kube cishe ama-3%, futhi ama-agents angenisa umoya kufanele asetshenziswe ngokuqapha. Kodwa-ke, ukusetshenziswa kwama-ejenti okufaka umoya kunezinzuzo eziningi ukwedlula ezingezinhle ekwenzeni ukhonkolo onjenge-anti-free kanye ne-anti-permeability.
. Ngesikhathi sokwakha, i-antifieze ehlanganisiwe enamanzi, ukufakwa komoya, okulwa nokuqhwa kanye namanzi okusebenza kusenesikhathi kuyasetshenziswa. Umsebenzi oyinhloko we-Antifreeze Yamandla Emandla Emanzi ahlanganisiwe ukunciphisa ukusetshenziswa kwamanzi futhi unciphise kakhulu amanzi angenawo amahhala ku-cydration, ngaleyo ndlela anciphise inani leqhwa. I-ejenti yokungena emotweni yokungena komoya ikhiqiza inani elikhulu lama-micro-bubble avaliwe ngokhonkolo omusha, adambisa amandla okunwebeka amavolumu okuqaqa ngokhonkolo, futhi avumela ukukhokhwa kweqhwa, futhi kuvumela ukhonkolo ukuthi aqhubeke nokuwashaywa amazinga okushisa angezinhle. Ingxenye yamandla okuqala e-ejenti yokungena komoya isheshisa i-hydration yengxube futhi iqinise kusenesikhathi, ihlangabezana namandla abucayi ngokushesha okukhulu nokugwema ukulimala kokuqala kokuqhwa. Ama-nitrate, ama-nitrites nama-carbonates anezakhi ze-antifreeze futhi azilungele ukulungiswa kwe-galvaning kanye nokuqiniswa kokhonkolo. Ukhonkolo wokuphuza amanzi nobunjiniyela bokudla ngeke basebenzise izingxenye ze-antifreeze aqukethe i-chromium usawoti amandla e-ejenti, i-nitrite kanye ne-nitrate. I-Antifreeze equkethe izakhi ze-urea akufanele isetshenziswe ezakhiweni zokuhlala kanye nezakhiwo zentengiso.
