1. Izinga lokunciphisa amanzi liyaguquguquka ukusuka phezulu ukuya phantsi, okwenza kube nzima ukulawula ngexesha leprojekthi.
Izixhobo zokuthengisa ze-polycarboxylic acid-based-based-agent-agent-based-agent-agent-agent-based-agent-agent-agent-based-agent-a-water-based-agent-agent-agent-based-agent-a-water-based-agent-agent--water-based-agent-agently-super-super-super-recung-water-recutures effects, such as to water-recung rate of 35% or even 40%. ” Ngamanye amaxesha izinga lokunciphisa amanzi ngokwenene liphezulu kakhulu xa evavanywa elabhoratri, kodwa xa kuziwa kwindawo yeprojekthi, ihlala imangalisa. Ngamanye amaxesha izinga lokunciphisa amanzi lingaphantsi kwama-20%. Enyanisweni, izinga lokunciphisa amanzi liyinkcazo engqongqo kakhulu. Ibhekisela kuphela ekusebenziseni i-sement ye-benchmark, umlinganiselo othile wokuxuba, inkqubo ethile yokuxuba, kunye nokulawulwa kwe-concrete slump ukuya (80 + 10) mm ngokuhambelana ne-"Concrete Admixtures" ye-GB8076 eqhelekileyo. idatha elinganiswe ngelo xesha. Nangona kunjalo, abantu bahlala besebenzisa eli gama kwiimeko ezininzi ezahlukeneyo ukubonisa umphumo wokunciphisa amanzi kwiimveliso, ezihlala zikhokelela ekungaqondani.
2. Ubuninzi be-arhente yokunciphisa amanzi, ngcono umphumo wokunciphisa amanzi.
Ukuze kulungiswe ikhonkrithi ephezulu kunye nokunciphisa umlinganiselo wesamente yamanzi, ubunjineli kunye nabasebenzi bezobugcisa bahlala befuna ngokuqhubekayo ukunyusa inani le-polycarboxylate yokunciphisa amanzi ukuze bafumane iziphumo ezilungileyo. Nangona kunjalo, umphumo wokunciphisa amanzi we-polycarboxylic acid-based agent yokunciphisa amanzi ixhomekeke kakhulu kwidosi yayo. Ngokuqhelekileyo, njengoko i-dosage ye-ejenti yokunciphisa amanzi inyuka, izinga lokunciphisa amanzi liyenyuka. Nangona kunjalo, emva kokufikelela kwidosi ethile, umphumo wokunciphisa amanzi nokuba "uyancipha" njengoko idosi isanda. Oku akuthethi ukuba umphumo wokunciphisa amanzi uyancipha xa umthamo unyuswa, kodwa ngenxa yokuba ukopha okukhulu kwenzeka kwikhonkrithi ngeli xesha, umxube wekhonkrithi uqina, kwaye umbane kunzima ukubonakalisa indlela yokudilika.
Ukuqinisekisa ukuba iziphumo zovavanyo lweemveliso zepolycarboxylic acid superplasticizer zonke ziyayifezekisa imigangatho, umthamo wemveliso ochaziweyo xa ungeniswa ukuba uhlolwe awunakuba phezulu kakhulu. Ngoko ke, ingxelo yokuhlolwa komgangatho wemveliso ibonisa kuphela idatha esisiseko, kwaye umphumo wesicelo wemveliso kufuneka usekelwe kwiziphumo zovavanyo zangempela zeprojekthi.
3. Ikhonkrithi elungiselelwe nge-polycarboxylate i-agent yokunciphisa amanzi yopha kakhulu.
Izalathi ezibonisa ukusebenza kwemixube ekhonkrithi ngokuqhelekileyo ziquka ulwelo, ukudibanisa kunye nokugcinwa kwamanzi. Ikhonkrithi elungiselelwe nge-polycarboxylic acid-esekelwe kwi-admixtures yokunciphisa amanzi ayisoloko ihlangabezana ngokupheleleyo neemfuno zokusetyenziswa, kwaye iingxaki zolunye uhlobo okanye ezinye zihlala zisenzeka. Ke ngoko, kuvavanyo lokwenyani, sihlala sisebenzisa amagama anje ngokuba sesichengeni samatye kakhulu kunye nokugcwala, ukopha kakhulu kunye nokwahlulahlula, ukufumba kunye nokusezantsi ukuchaza ngokucacileyo ukusebenza kwemixube yekhonkrithi. Iimpawu zemixube yekhonkrithi elungiselelwe kusetyenziswa uninzi lweearhente zokunciphisa amanzi ezisekwe kwipolycarboxylic acid zinovakalelo kakhulu ekusetyenzisweni kwamanzi.
Ngamanye amaxesha ukusetyenziswa kwamanzi kwandisa kuphela (1-3) kg / m3, kwaye umxube wekhonkrithi uya kuphuma igazi kakhulu. Ukusebenzisa olu hlobo lomxube akunakuqinisekisa ukufana kokugalela, kwaye kuya kuba lula ukukhokelela emigodini, kwisanti, kunye nemingxuma kumphezulu wesakhiwo. Iziphene ezinjalo ezingamkelekanga zikhokelela ekunciphiseni amandla kunye nokuqina kwesakhiwo. Ngenxa yokulawulwa kwe-lax ekubhaqweni kunye nokulawulwa komswakama odibeneyo kwizikhululo zokuxuba zekhonkrithi, kulula ukongeza amanzi amaninzi ngexesha lokuvelisa, okukhokelela ekuphumeni kwegazi kunye nokwahlulwa komxube wekhonkrithi.
