Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
ikhonkrithi eyongezayo yokunciphisa amanzi superplasticizer yikhemikhali esetyenziselwa ukwenza imixube yekhonkrithi ihambe lula. Ifumaneka njengomgubo okanye ulwelo kwaye inokongezwa kumxube njengoko ifuneka ekusebenzeni okufunwayo. Isebenza ngokunciphisa umlinganiselo wamanzi / wesamente kunye nokuvumela amandla aphezulu ekhonkrithi kunye nokunyanzeliswa okuphantsi. Isenokukhawulezisa okanye ibambezele ukusetwa kwekhonkrithi ngokwemichiza yayo. Ingasetyenziswa kwizicelo eziphezulu zekhonkrithi ezifana nokumpompa, ikhonkrithi ezizidibanisayo (SCC), ukufikeleleka okuphantsi kunye nokufunxa kwamanzi aphantsi.
Imixube yekhonkrithi exutywe kunye nabanciphisi bamanzi ine-slump ephantsi kunabo bangenayo. Oku kwenza kube lula ukusebenza ikhonkrithi ngesandla kwaye konga kwiindleko zabasebenzi. Umxube wokunciphisa umgangatho wamanzi unokunyusa ukudilika komxube wekhonkrithi ngaphandle kokutshintsha umxholo wesamente..
Umxube wokunciphisa amanzi ungasetyenziswa ngokudityaniswa nezinye izixube ezifana neseti yeretarders., ii-arhente zokungenisa umoya, umsi we-silica kunye nokubhabha uthuthu. Ezi zidibaniso zinokunceda ukuhlangabezana neemfuno zokusebenza kweeprojekthi ezinjengeekholomu ezide, i-slabs ephezulu yomgangatho ophezulu okanye i-abrasion resistant hydraulic structures.
Ukongeza ekunciphiseni amanzi, izongezo zekhonkrithi ezifana ne-superplasticizers zingasetyenziselwa ezinye iinjongo ezinjengokubambezela iseti yokuqala yekhonkrithi okanye ukwandisa amandla ayo okuguquguquka.. Ezinye ziyafumaneka njenge-chloride-free set accelerators ezinokuthi zisetyenziswe kwi-precast okanye ikhonkrithi egxininisiweyo ngaphandle kokuchaphazela kakubi amandla okugqibela ekhonkrithi.. Ezinye izongezo zolawulo lwe-hydration ezivumela iikontraki ukuba zifumane eyona konkrithi ngokulawula ukuhanjiswa kwamanzi kunye nobungakanani bamasuntswana esamente..
