Ukusetyenziswa kwemixube ukuphucula izibonelelo ezinxulumeneyo:
Ikhonkrithi exutywe nezongezo ezinxulumeneyo, ezifana ne-arhente yokunciphisa amanzi asebenzayo kunye ne-arhente yamandla okuqala, inokwenza ikhonkrithi yeentsuku ezi-7 zamandla ngaphezu kwamaxesha e-1, ukunciphisa izinga lokuphuma kwegazi, ukuphucula izinga lokunciphisa amanzi, kunye neentsuku ezingama-28 emva komlinganiselo wamandla oxinzelelo. inokufikelela ngaphezu kwe-150%, ngoko ke ekulungiseleleni amandla aphezulu okanye i-concrete ye-ultra ephezulu kulula ukuyifumana.Ngamandla ekhonkrithi exutywe ne-admixture iphucula ngaxeshanye, iphucula ukusebenza kwayo kunye nokukhuselwa kwamanzi, kwaye ulungelelanise umxholo womoya, uphucule uxhathiso lwe-corrosion, i-alkali aggregate reaction, iphucula ukuxhathisa umhlwa, ukuphucula amandla adibeneyo, oku kungekuphela nje. ukwandisa ukusetyenziswa koluhlu lwekhonkrithi, kwaye ugcine izinto zokwakha, ugcine isamente okanye utshintshe i-samente ekhethekileyo.Kwaye kwikhonkrithi exutywe kunye ne-arhente yokunciphisa amanzi yodidi olucothayo, inokuhlengahlengisa ixesha lokumisela, ukuphucula ukumpompa, ukulibaziseka kwexesha lokubeka ikhonkrithi kunye nexesha lokuqina, lingahlangabezana nobunjineli obuhlukeneyo, ngokukodwa ukwakhiwa kobunjineli bekhonkrithi kunye neemfuno zomgangatho.Xa ukhetha i-admixture kwikhonkrithi, kuyimfuneko ukuqwalasela iimpawu zeentlobo zesamente kunye nezinye izinto ngexesha elifanayo, kwaye ukhethe iintlobo ezahlukeneyo ze-agent yokunciphisa amanzi ngokweenjongo ezahlukeneyo.Xa ukhetha i-arhente yokunciphisa amanzi, kuyimfuneko ukuqwalasela uqoqosho kwaye ubeke ingqalelo ekuzinzeni komgangatho we-arhente yokunciphisa amanzi.Ukuba ukuhlangabezana nengxaki ukuba isamente kunye admixture musa ukuziqhelanisa, kufuneka aphelise umba ochaphazelekayo ngovavanyo, khetha uhlobo arhente yokunciphisa amanzi ezifanelekileyo, uhlalutyo isamente ixhalabele ingxaki umgangatho, ukumisela ubungakanani admixture efanelekileyo, ikhonkrithi mix ratio impembelelo.Kusetyenziso oluxubeneyo lwemixube emininzi, kuyafuneka ukuba kuqwalaselwe ukuhambelana phakathi kweendidi kunye nempembelelo yokusebenza kwekhonkrithi, kufuneka ivavanywe ngaphambi kokusetyenziswa, njengenkqubo yepolycarboxylic acid esebenza kakhulu kwisinciphisi samanzi kunye nenkqubo ye-naphthalene yokunciphisa amanzi akufuneki ibe. ukusetyenziswa okudibeneyo.Ngophuhliso kunye nokusetyenziswa kwe-concrete admixture, iye yoyisa ubuthathaka bamandla aphantsi, i-brittleness ephezulu kunye nokunye, kwaye yaqinisekisa ukuqhubeka kolwakhiwo, yanciphisa kakhulu umda wexesha, yakhuthaza ukuphuhliswa kobuchwephesha bokuhamba kwekhonkrithi kunye nobuchwepheshe obutsha bokupompa kunye ne-teknoloji entsha. ukugalela, kunye nokukhawulezisa uphuhliso lwekhonkrithi yorhwebo.Uphuhliso lwekhonkrithi yorhwebo luzise izibonelelo ezilungileyo zoqoqosho kunye neenzuzo zokhuseleko lokusingqongileyo kushishino lwezokwakha lwaseTshayina, kwaye lwakhuthaza ngakumbi uphuhliso loshishino lokwakha kunye nokuphuculwa kobugcisa bokwakha.
Iindlela zobugcisa zokuqonda ukusetyenziswa kwamanzi okuphantsi kulwakhiwo lwekhonkrithi:
Iimpawu zekhonkrithi zokusetyenzwa kukuhamba kunye nokulawula amandla ayo, ikakhulu kuxhomekeke kwiyunithi yekhonkrithi yokusetyenziswa kwamanzi kunye nomlinganiselo wesamente yamanzi (umlinganiselo wesamente yamanzi).Xa uyila umlinganiselo womxube wekhonkrithi ephezulu yokusebenza, ukusetyenziswa kwamanzi kuseza kuhlangabezana nokusebenza kwayo njengemeko, ngokuphindaphindiweyo ubungakanani bokusetyenziswa kwamanzi, ukulawula umgangatho wamandla okhonkrithi yinto ngqo.
Ngamanye amaxesha xa ungasebenzisi isongezo, usebenzisa amanzi athile ngelixa uhlangabezana neemfuno zokusetyenzwa) (oko kukuthi, ukudilika, kodwa ubunzulu bayo buhlala bungakwazi ukuqhubela phambili, kwaye awukwazi ukuhlangabezana namandla oyilo, oku kungenxa yokuba umlinganiselo wesamente yamanzi. , kunye nomlinganiselo wesamente kunye nokuhlangabezana neemfuno zokuchazwa, ngoko ke akayi kuba nako ukuyila umlinganiselo wokuxuba ofanelekileyo;
Ikhonkrithi kwinqanaba eliphantsi lokuwa, amandla alula ukuphucula, kodwa ukusebenza kwawo akunjalo.Ngoko ke, ukuze kuqinisekiswe ukusebenza kunye nokuqinisekisa ukuba amandla awancitshiswanga okanye aphuculwe, kufuneka sisebenzise i-admixture efanelekileyo.Uninzi lwamanzi alulwelo lokunciphisa isiphumo sekhonkrithi kunye ne-arhente yokunciphisa amanzi asebenzayo, ukuphucula ukusebenza kwekhonkrithi, kunye nokunciphisa umthamo wesamente, kungekuphela nje ukuphumeza ibakala elifanayo lekhonkrithi, gcina i-15% ~ 25% yesamente, kwaye yenza ukwakhiwa kwekhonkrithi, ukusebenza kakuhle. ukuphucula ukungakwazi ukuhlawula amatyala, iindleko eziphantsi, ukuhlangabezana kakhulu nemfuneko yolwakhiwo lwangoku kunye neemfuno zobunjineli ezikhethekileyo.
