I-concrete admixtures, ebizwa ngokuba yi-admixtures emfutshane, ibhekisela kwizinto ezongezelelweyo ngaphambi okanye ngexesha lokuxutywa kwekhonkrithi ukuphucula iimpawu zekhonkrithi entsha kunye / okanye i-concrete eqinile. Iimpawu ze-concrete admixtures zininzi iintlobo kunye
idosi encinci, edlala indima ebalulekileyo ekuguqulweni kwekhonkrithi. Ngophuhliso oluthe ngcembe lweshishini lokwakha, imfuno yekhonkrithi kwiiprojekthi zobunjineli iyaqhubeka nokukhula, kwaye kwangaxeshanye, kukho iimfuno eziphezulu zokusebenza kunye nomgangatho wekhonkrithi. Kulo mxholo, njengesixhobo sobunjineli esibalulekileyo esinokuphucula kakhulu ukusebenza kwekhonkrithi, imixube yekhonkrithi ibe licandelo lesihlanu eliyimfuneko kwikhonkrithi yale mihla ngaphandle kwesamente, isanti, ilitye kunye namanzi.
I-ejenti ephezulu yokunciphisa amanzi I-arhente yokunciphisa amanzi ihlukaniswe ngokukodwa kwiindidi ezintathu: i-ejenti eqhelekileyo yokunciphisa amanzi, i-ejenti ephezulu yokunciphisa amanzi kunye ne-ejenti ephezulu yokunciphisa amanzi. Ukuphuhliswa kwee-superplasticizers kuye kwadlula izigaba ezintathu: isizukulwana sokuqala se-superplasticizers eziqhelekileyo ezimelwecalcium yomthi, isizukulwana sesibini se-superplasticizers esimelwe nguinaphthaleneseries, kunye nesizukulwana sesithathu superplasticizers imelwe ngui-polycarboxylate superplasticizeruthotho. Isizukulwana senqanaba eliphezulu le-superplasticizer.Polycarboxylate superplasticizerineenzuzo zedosi ephantsi kunye nokunciphisa amanzi aphezulu, kwaye ingasetyenziselwa ukwenza amandla aphezulu, amandla aphezulu, ukuqina okuphezulu kunye ne-super-fluid concrete; Inkqubo ayinalulwelo lwenkunkuma, irhasi eyinkunkuma, ukukhutshwa kwentsalela yenkunkuma kunye nezinye izinto. Yi-ejenti yokunciphisa amanzi eluhlaza kunye nokusingqongileyo, kwaye ineenzuzo ezicacileyo ekukhuselweni kwendalo kunye nokusebenza kakuhle. Ngokwandiswa komthamo wemveliso kunye nokuphuculwa kokungena, iipolycarboxylate superplasticizers ziye zaba zezona ntlobo ziphambili ze-superplasticizers eziveliswayo ngoku kwaye zisetyenziswe kwilizwe lam.
Kumxholo "wokukhula okuzinzileyo" okulindeleke ukuba kuqhubeke ukufudumala, ukwanda kwemfuno yekhonkrithi eziswa kukwanda kokucwangciswa kweeprojekthi ezinkulu zobunjineli kunye nokuqhubela phambili kweshedyuli yokwakha kuya kwandisa imfuno ye-concrete admixtures. kwangelo xesha. Ukongeza, ngokweengxelo zomsebenzi karhulumente okhutshwe ngamaphondo ahlukeneyo, ulwakhiwo lweziseko zophuhliso olunje ngezothutho kunye neeprojekthi zogcino lwamanzi zenza inxalenye enkulu yeeprojekthi ezinkulu, kwaye ezi projekthi zikhankanywe ngasentla zineemfuno eziphezulu zokusebenza kwekhonkrithi, kunye namanzi asebenza kakhulu. abanciphisi bayafuneka ukuhlangabezana neemfuno zekhonkrithi. Xa kuthelekiswa nezinye iintlobo zemixube, iimfuno zokwakha zokumpompa kunye nokunciphisa ukungcangcazela kunye neemfuno ezingenazo ukungcangcazela kweeprojekthi ezikhethekileyo zekhonkrithi zineengenelo ezicacileyo. Ke ngoko, ubungakanani bemfuno yeearhente eziphezulu zokunciphisa amanzi ezinokuthi zifezekise iiprojekthi zobunjineli "ezenziwe" ziya kulindeleka ukuba zinyuke ngakumbi.
Ishishini lezinto ezisebenzayo zeJufu Chemical Company ngaphandle kweshishini eliphambili lee-superplasticizers libonisa ingqiqo yemveliso esisiseko eyahluke kakhulu kwabo bakhuphisana nayo. Kwixesha elizayo, iya kuba nakho ukuphindaphinda impumelelo yeshishini le-superplasticizer, kwaye isilingi yendawo yentengiso iphezulu kakhulu kuneye-superplasticizers.
