Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
superplasticizer ukhonkolo iyinhlanganisela ebalulekile esetshenziswa ekukhiqizeni ukhonkolo osebenza kahle kakhulu. Kuyasiza ukuthuthukisa ukusebenza namandla kakhonkolo osebenza kakhulu ngokuhlangana ne-silica fume, fly umlotha, i-slag, noma ezinye izengezo.
Ama-Superplasticizers (SP) ama-macromolecules ancibilikayo, izikhathi ezingamakhulukhulu kunama-molecule amanzi. Bakhanga ku-C3A ngezinhlayiya zikasimende futhi bakhulule amanzi avalelwe.
Engxubeni kakhonkolo, lawa ma-superplasticizers anezelwa ngesilinganiso esiphansi ngenani eliphakeme kakhulu 2 iphesenti lamanzi esewonke. Ingxube ke ixutshwe okungenani 3 imizuzu nge-drill mechanical noma 5 imizuzu nge-mixer yodaka.
Ukwengezwa kwama-superplasticizers kunciphisa inani lamanzi emixubeni kakhonkolo ngaphandle kokunciphisa amandla noma ukusebenza kwengxube.. Lokhu kungonga imali eningi ezintweni zokwakha kanye nesikhathi.
Kuyasiza futhi ukuvimbela ukuhlukaniswa kumamiksi asekelwe ekuhlanganiseni.
Inkinga evamile ngokusebenzisa ama-superplasticizers ukuthi avame ukulahlekelwa ukusebenza kwawo ngokushesha. Lokhu kungase kubangele ubunzima lapho ubeka ukhonkolo njengoba amaloli asele exubile kufanele akwazi ukuthatha uhambo olude phakathi kwezindawo zomsebenzi..
Lezi zinkinga zingaxazululwa ngokusebenzisa okuphambene ne-high range water reducer: i-viscosity yokuguqula izixube (I-VMA). Ama-VMA ayingxube eyimpuphu enciphisa ukuwohloka kukakhonkolo futhi esiza ukuvimbela ukuhlukaniswa kukhonkolo esekwe ku-aggregate..
Amandla amakhonkrithi asebenza kahle kakhulu aqukethe i-SMF ne-SNF-superplasticizers aphakeme kunalawo okhonkolo wereferensi owenziwe endaweni efanayo yokudilika ngaphandle kokuxutshwa., noma amanzi:isilinganiso sikasimende siyalingana. Nokho, ukuthuthukiswa kwamandla kudalwe ikakhulukazi ukuncipha kokuqukethwe kwamanzi okubangelwa ukusetshenziswa kwalezi zixube..
