Ukusetshenziswa kwezixube ukuthuthukisa izinzuzo ezihlobene:
Ukhonkolo oxutshwe nezithasiselo ezihlobene, njenge-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-ejenti yamandla angaphambi kwesikhathi, ungenza ukhonkolo wezinsuku ezingu-7 zamandla izikhathi ezingaphezu kwesi-1, unciphise izinga lokopha, uthuthukise izinga lokunciphisa amanzi, futhi ezinsukwini ezingu-28 ezivamile ngemva kwesilinganiso samandla acindezelayo. ingafinyelela ngaphezu kwe-150%, ngakho-ke ekulungiseleleni amandla aphezulu noma ukhonkolo we-ultra high amandla kulula ukufeza.Ngamandla kakhonkolo oxubene ne-admixture ngcono ngesikhathi esifanayo, uthuthukise ukusebenza kwawo kanye nokuphuma kwamanzi, futhi ulungise okuqukethwe komoya, uthuthukise ukumelana nokugqwala, ukusabela kwe-alkali aggregate, uthuthukise ukumelana nokugqwala kwensimbi, uthuthukise amandla ahlangene, hhayi lokhu kuphela. wandise uhla olusetshenziswayo lukakhonkolo, futhi wonge izinto zokwakha, ukonga usimende noma ubuyisele usimende okhethekile.Futhi ku-concrete exutshwe ne-ejenti yokunciphisa amanzi yokusetha kancane, ingalungisa isikhathi sokusetha, ithuthukise ukudonsa, ibambezele isikhathi sokusetha ukhonkolo kanye nesikhathi sokuqina, ingahlangabezana nobunjiniyela obuhlukene, ikakhulukazi ukwakhiwa kobunjiniyela obukhulu kanye nezidingo zekhwalithi.Lapho ukhetha i-admixture kukhonkolo, kuyadingeka ukucabangela izici zezinhlobonhlobo ze-samente nezinye izingxenye ngesikhathi esifanayo, futhi ukhethe izinhlobo ezahlukene ze-ejenti yokunciphisa amanzi ngokwezinjongo ezahlukene.Lapho ukhetha i-ejenti yokunciphisa amanzi, kuyadingeka ukucabangela umnotho futhi unake ukuzinza kwekhwalithi ye-ejenti yokunciphisa amanzi.Uma kuhlangatshezwana nenkinga usimende nengxubevange ingakujwayeli, kumele isuse into ethintekayo ngokuhlolwa, ikhethe uhlobo olufanele lwe-ejenti yokunciphisa amanzi, ukuhlaziywa kukasimende kumayelana nenkinga yekhwalithi, kunqume inani elifanele lengxubevange, ithonya lesilinganiso senhlanganisela kakhonkolo.Ekusetshenzisweni okuhlanganisiwe kwezixube eziningana, kuyadingeka ukunaka ukuhambisana phakathi kwezinhlobonhlobo nomthelela wokusebenza okukhonkolo, kufanele kuhlolwe ngaphambi kokusetshenziswa, njenge-polycarboxylic acid system esebenza kahle kakhulu yokunciphisa amanzi kanye nesistimu yokunciphisa amanzi ye-naphthalene akufanele ihlolwe. ukusetshenziswa okuhlanganisiwe.Ngokuthuthukiswa kanye nokusetshenziswa kwe-concrete admixture, inqobe ubuthakathaka bamandla aphansi, i-brittleness ephezulu nokunye, futhi yaqinisekisa ukuqhubeka kokwakhiwa, yanciphisa kakhulu umkhawulo wesikhathi, yakhuthaza ukuthuthukiswa kobuchwepheshe bokugeleza kokhonkolo kanye nobuchwepheshe obusha bokupompa kanye. ukuthulula, futhi kusheshiswe ukuthuthukiswa kokhonkolo kwezohwebo.Ukuthuthukiswa kukakhonkolo wezohwebo kulethe izinzuzo ezinhle zezomnotho kanye nezinzuzo zokuvikela imvelo embonini yezokwakha yaseShayina, futhi kwaqhubekisela phambili ukuthuthukiswa kwemboni yezokwakha kanye nokwenza ngcono ubuchwepheshe bokwakha.
Izindlela zobuchwepheshe zokubona ukusetshenziswa kwamanzi okuphansi ekwakhiweni kukakhonkolo:
Ukhonkolo izici ukusebenza ukugeleza nokulawula amandla ayo, ikakhulukazi kuncike ukhonkolo iyunithi ukusetshenziswa kwamanzi kanye amanzi usimende isilinganiso (amanzi usimende isilinganiso).Lapho uklama isilinganiso sengxube sokukhonkolo sokusebenza okuphezulu, ukusetshenziswa kwamanzi kusazohlangabezana nokusebenza kwawo njengoba isimo, ngokuvamile inani lokusetshenziswa kwamanzi, ukulawula izinga lamandla okukhonkolo kuyisici esiqondile.
Kwesinye isikhathi uma ungasebenzisi isithasiselo, usebenzisa amanzi athile ngenkathi uhlangabezana nezidingo zokusebenza) (okungukuthi, ukuwohloka, kepha ukuqina kwawo akuvamile ukuqhubekela phambili, futhi ngisho nokungakwazi ukuhlangabezana namandla okuklama, lokhu kungenxa yokuthi isilinganiso sikasimende samanzi , kanye nesilinganiso sikasimende kanye nokuhlangabezana nezidingo zokucaciswa, ngakho-ke ngeke akwazi ukuklama ingxenye efanelekile yengxube;
Ukhonkolo ngezinga eliphansi lokuwa, amandla alula ukuthuthuka, kodwa ukusebenza kwawo akunjalo.Ngakho-ke, ukuze siqinisekise kokubili ukusebenza kanye nokuqinisekisa ukuthi amandla awancishisiwe noma awathuthukisiwe, kufanele sisebenzise i-admixture efanele.Amanzi amaningi oketshezi okunciphisa umphumela kakhonkolo nge-ejenti yokunciphisa amanzi esebenza kahle kakhulu, athuthukisa ukusebenza kukakhonkolo, futhi anciphise umthamo kasimende, hhayi nje ukufeza ibanga elifanayo likakhonkolo, longa i-15% ~ 25% kasimende, futhi lenza ukwakhiwa kokhonkolo, ukusebenza kahle. thuthukisa i-liquidity, izindleko eziphansi, ukuhlangabezana kakhulu nemfuneko yokwakhiwa kwesimanje kanye nezidingo ezikhethekile zobunjiniyela.
