isebenza njani i-superplasticizer
Ukuveliswa kwekhonkrithi kusekelwe kwimpendulo yekhemikhali edibanisa amanzi kunye nesamente kunye neengqungquthela ezintle (isanti okanye ilitye elityumkileyo) kunye neeaggregates ezirhabaxa. Le nkqubo ivelisa intlama yesamente ene-hydrated ezinzileyo kwaye ixinene ngokwaneleyo ukuba ibambene kunye nentsimbi yokuqinisa..
Kubalulekile ukuba umlinganiselo ochanekileyo wamanzi wongezwe ukuze ufezekise amandla afunekayo kunye nokuqina kwemveliso yokugqibela. Amanzi amaninzi anokunciphisa ukuqina kwekhonkrithi.
Kukho iintlobo ezininzi ze-admixtures ezinokuthi zisetyenziswe ukutshintsha iipropati zekhonkrithi kunye nokuphucula amandla ayo okwenza kwiimeko ezininzi ezahlukeneyo.. Banokunciphisa ixesha lokumisela ikhonkrithi, ukwandisa amandla ayo kwangoko, nciphisa umthamo wamanzi okanye uthobe isantya sokugalela amanzi.
Zingasetyenziselwa ukunyusa ukuhamba kwekhonkrithi. Oku kuphunyezwa ngokusasaza amasuntswana e-samente kumxube wokwandisa ubumanzi.
Le yindlela esebenzayo kakhulu yokuphucula ukusebenza kwekhonkrithi. Esi sesona sizathu sibalulekileyo sokuba iiplastiki zongezwa kwimixube yekhonkrithi.
Isenzo sokusasazwa kweeplasticizers siphucula kakhulu ukusebenza kwekhonkrithi kumlinganiselo onikiweyo wesamente yamanzi kunye nomxholo wamanzi., kangangokuba inokubekwa ngomzamo omncinci ohlangeneyo kwaye ngokoqobo ngaphandle kokuphuma kwegazi okanye ukwahlukana.
I-Superplasticizers luhlobo olutsha lwe-concrete admixtures enokongezwa kwimixube yekhonkrithi. Banokunciphisa umthamo wamanzi womxube ukuya kuthi ga 30% kwaye inokuphucula ukusebenza kwayo ngokunyusa ukuwohloka. Zingasetyenziselwa kwikhonkrithi entsha kunye neqinile ukunciphisa umthamo wamanzi okanye ixesha lokumisela.
