Kusarudzwa kweConcrete Admixture:
. yekongiri ine zvakakosha zvinodiwa simba rekutanga, shandisa chidimbu-chinokurumidza simende kana kuwedzera silica fume; Paunenge uchishandisa Silica fume yekongiri inoda kuparara, uye kana yakakura-yakawanda-yakakwirira kongiri inoda kudzikisira kupisa kwe hydration, huwandu hwesimbe hunofanirwa kuderedzwa uye silica fume kana kubhururuka ash inofanira kuwedzerwa. Iyo yekutanga yekuisa nguva yekongiri yakavhenganiswa neyekuita-maitiro emvura-kuderedza mumiririri kwenguva yakareba kupfuura iyo yeakajaira kongiri. Iyo yakakura iyo mari, iyo refu iyo yekutanga yekuedza nguva.
(2. Wedzera imwe huwandu hwemhepo zvemhepo kuenda kongiri, uye kana iyo mhepo yemukati inowedzera ne1%, simba rinoderera ne5%. Naizvozvo, kana uchigadzirira yakakwira-simba giredhi kongiri, izvo zvemhepo zvinofanirwa kunge zviri zve3%, uye mhepo-inopinda mumhepo zvinofanirwa kushandiswa nekuchenjerera. Nekudaro, kushandiswa kwemhepo-yekupindira mumhepo kune zvakanakira kupfuura zvakashata pakuita kongiri yakadai seanti-yakasununguka uye anti-permabilde.
. " Munguva yekuvakwa, diafree yakaomeswa ine mvura-inoderedza mvura, mhepo-yekupindira, inoshungurudza-kusunungura uye yekutanga-simba zvikamu zvinoshandiswa. Basa guru remuchisimbe-simba raida kuderedza mvura yekusanganisa mvura uye zvakanyanya kuderedza mvura yakawandisa yemahara mumuviri, nekudaro ichidzora huwandu hwekusununguka. Mhepo yemhepo-inopinda mumiririri inogadzira huwandu hwakakura hwemapepa akavharwa micro-bubbles muvheni yekuwedzera, inoderedza nzvimbo yekudzika, uye inobvumira kongiri kuti ienderere mberi nehyrates yekupisa. Iyo yekutanga-simba chikamu mumhepo-yekukwira mumiririri inowedzera hydration yemusanganiswa uye ichisimbisa pakutanga, kusangana neiyo simba rekutsoropodza nekukurumidza uye kudzivisa kukuvara kwekutanga. Nitrates, maNitrites uye carbonates fanifreeze zvikamu uye haana kukodzera kurongedza uye akasimbisa kongiri admerte. Concrete yekunwa mvura uye yeinjiniya yekudya haizoshandise antifreeze zvikamu zvine chromium munyu wekutanga mumiriri, Nitrite uye Nitrate. AntiFreeze ane urea zvikamu hazvifanirwe kushandiswa muzvivakwa zvekugara uye zvivakwa zvekutengeserana.
