Kusarudzwa kwekongiri yakasanganiswa:
(1) Inoshanda uye yepamusoro-inoshanda-inoderedza mvura: Sezvo kunyunguduka kwekrete kunonyanya kugadziriswa nepamusoro-soro yemvura-inoderedza mumiriri, iyo dosage inotora 1% kusvika 2% yehuremu hwesamende;kwekongiri ine zvakakosha zvinodiwa zvesimba rekutanga, shandisa kukurumidza-kuisa simende kana Wedzera silica fume;paunenge uchishandisa silica fume yekongiri inoda kusakara, uye kana hombe-vhoriyamu yakakwirira-yakasimba kongiri inoda kudzikisira kupisa kwemvura, huwandu hwesimende hunofanira kudzikiswa uye utsi hwesilica kana dota renhunzi rinofanira kuwedzerwa.Nguva yekutanga yekugadzika kongiri yakasanganiswa neyepamusoro-inoshanda-yekudzikisa mvura mumiririri yakareba kupfuura iyo yekongiri yakajairika.Iyo yakawanda, iyo yakareba nguva yekutanga yekuseta.
(2) Air-entraining agent uye air-entraining water-deduction agent: Inodiwa kuti ive nepamusoro-soro yechando uye yakakwirira density, uye inofanira kusanganiswa nemhepo-entraining agent kana air-entraining-water-deduction agent.Wedzera humwe huwandu hwemhepo kune kongiri, uye kana mhepo yemukati ichiwedzera ne1%, simba rinoderera ne5%.Nokudaro, paunenge uchigadzirira kongiri yepamusoro-soro, mhepo yemhepo inofanira kunge inenge 3%, uye mhepo-intraining agents inofanira kushandiswa nekuchenjerera.Zvisinei, kushandiswa kwemhepo-entraining agents kune zvakawanda zvakanakira pane zvisingabatsiri pakushanda kwekrete yakadai se-anti-freeze uye anti-permeability.
(3) Kusarudzwa kweAntifreeze: Paunenge uchiisa kongiri yakasimba-yakasimba munguva yechando, tanga wasarudza antifreeze inokodzera tembiricha yepakati inotarisirwa panguva yekudira.Panguva yekuvaka, antifreeze yakasanganiswa nemvura-inoderedza, air-entraining, anti-freezing uye yekutanga-simba zvikamu zvinoshandiswa.Basa guru rekutanga-simba antifreeze nderokuderedza kusanganiswa kwemvura kushandiswa uye kuderedza zvakanyanya kuwandisa kwemvura yakasununguka mu simenti hydration, nokudaro kuderedza kuwanda kwechando.The composite air-entraining agent inogadzira nhamba yakawanda yakavharwa micro-bubbles mukrete itsva, iyo inoderedza simba rekuwedzera vhoriyamu yechando pakrete, inoderedza nzvimbo yechando, uye inobvumira kongiri kuti irambe iine hydrate pakupisa kusina kunaka.Iyo yekutanga-simba chikamu mumhepo-inopinza mumiriri inomhanyisa hydration yemusanganiswa uye inoisimbisa nekukurumidza, kusangana nesimba rakakosha nekukurumidza uye kudzivirira kukuvara kwekutanga kwechando.Nitrates, nitrites uye carbonates inhengo dzeantifreeze uye hadzina kufanira galvanizing uye yakasimbiswa kongiri admixtures.Kongiri yemvura yekunwa uye engineering yekudya haifanire kushandisa antifreeze zvikamu zvine chromium munyu yekutanga simba agent, nitrite uye nitrate.Antifreeze ine urea components haifaniri kushandiswa muzvivako zvekugara uye zvivakwa zvekutengesa.
