1. Mvura-kuderedza concrete admixture
Mvura-kuderedza Admictures zvigadzirwa izvo kana zvakawedzerwa kuConcrete inogona kuumba iyo yadonhedza slump pane yakaderera mvura-simende yakagadzirwa kupfuura izvo zvinowanzogadzirwa. Mvura-kuderedza Admixture inoshandiswa kuwana chaiyo concrete simba uchishandisa pasi simenti yezvinyorwa. Yakadzika yeComment Mukati music Nerudzi urwu rwechibvumirano, zvivakwa zvine mwero zvinovandudzwa uye zvinobatsira nzvimbo kongiri mumamiriro ezvinhu akaoma. Mvura inoderedza yave ichishandiswa zvakanyanya mubhiriji decks, low-slump concrete inodarika, uye chibharo kongiri. Dzazvino kufambira mberi muAdmixture tekinoroji yakakonzera kukura kwepakati-mhando mvura inoderedza.
2. Concrete Admixture: Superplastionalzers
Chinangwa chikuru chekushandisa mashura ndewekuburitsa kongiri inoyerera neyakaomeswa mune zvinomwe kusvika pamasendimita akasimbiswa uye mukuvharirwa kwakaringana nekubvunzurudzwa hakugone kuwanikwa nyore. Iyo imwe huru application ndeyekugadzirwa kweakakwira-simba kongiri kuW / C's proming kubva 0.3 kusvika 0.4. Iyo yakawanikwa kuti kune mazhinji emhando dzeSement, Superplasticastizer inovandudza basa rekushanda kongiri. Rimwe dambudziko rakabatana nekushandisa yakakwira renji yemvura kuderedza mukokongiri kutsvedza kurasikirwa. Yakakwirira yekudzidzira kongiri ine sewakanyanya kuve yakajeka inogona kuitwa neyekukwirisa-thaw kuramba- thaw kuramba, asi zvemhepo zvinofanirwa kuwedzerwa hama yepamoyo pasina superplasticticastion.
3. Concrete Admixture: Set-Retarding
Gadza kudzoreredza kongiri yekubvumirana kunoshandiswa kunonoka kudzora kwemakemikari zvinoitika kana kongiri yatanga iyo yekuisa maitiro. Iyi mhando yekongiri yekuzvidavirira inowanzo shandiswa kuderedza mhedzisiro yekupisa kwakanyanya kunogona kuunza kukurumidza kutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekutanga kwekongiri. Gadza kudzoreredza Adminture inoshandiswa mukuvakwa kongororo, kubvumira nguva yakawanda yekupedza nzvimbo yemapepa ekupedza, kudzora mari yekuwedzera yekugadzira batch yekongiri uye inobatsira kubvisa majoini ekutonhorera muonghi. Dzinza dzinogona zvakare kushandiswa kudzivisa kupaza nekuda kweFomu deflection iyo inogona kuitika kana yakatwasuka slab inoiswa muzvikamu. Vazhinji vanodzoserawo zvakare basa semvura inoderedza uye vanogona kukwidza mhepo mune kongiri
4. Concrete Admixture: Mhepo-Inopinda Mumiriri
Mhepo inopinda kongiri inogona kuwedzera iyo freeze-thaw kujaira kwekongiri. Rudzi urwu rwekushamisika runoburitsa kongiri inoshanda pane isiri-yakakonzerwa kongiri paunenge uchideredza kubuda ropa uye kusarudzika kwejongwe nyowani. Yakavandudzika kuramba kongiri kuti isanyanya chando chiito kana kusununguka / thaw come. Zvimwe zvakanakira kubva pane izvi zvekushamisika nde:
a. Kupokana kwakanyanya kune kutenderera kwekunyorova uye kuoma
b. Dhigirii rakakwirira rekushanda
c. Yakakwirira Dhigirii Yekusimba
Iyo yakashongedzwa mhepo mabhurukuita seyakagwinya proffer inopesana nekupaza yakakonzerwa nekushushikana nekuda kwemvura vhoriyamu mukupisa kwekushisa tembiricha. Mhepo inonakidza admixture inoenderana neinenge nguva dzese kongiri. Kazhinji kune imwe neimwe muzana yemhepo yakapihwa mhepo, simba rekumanikidza rinozoderedzwa nevashanu muzana.
5. Concrete Admixture: Kukurudzira
Shrinkage-kuderedza concrete admenture inowedzerwa kune kongiri panguva yekutanga kusanganisa. Rudzi urwu rwekushamisika runogona kuderedza kutanga uye kwenguva refu kuoma kuoma shrinkage. Shrinkage kuderedza Adminture inogona kushandiswa mumamiriro ezvinhu anodzikira kupaza kunogona kutungamira kumatambudziko ekuzvishingisa kana kuti huwandu hukuru hwemajohts haafarirwe nezvikonzero zvehupfumi kana zvehunyanzvi. DriKige kuderedza kuderedza Admixture kunogona, mune zvimwe zviitiko, kuderedza kukura kwesimbe pakutanga uye gare gare mazera.

Shrinkage kuderedza Adminture inogona kushandiswa mumamiriro ezvinhu anodzikira kupaza kunogona kutungamira kumatambudziko ekuzvishingisa kana kuti huwandu hukuru hwemajohts haafarirwe nezvikonzero zvehupfumi kana zvehunyanzvi. DriKige kuderedza kuderedza Admixture kunogona, mune zvimwe zviitiko, kuderedza kukura kwesimbe pakutanga uye gare gare mazera.
7. Concrete Admixture: Corrosion-Inhibiting
Corrosion-inhibiting adminture inowira mugwara rakanyanya kuyaruka chikamu uye anoshandiswa kunonoka kudzora kwesimbi mukodhi. Corrostion Inhibitors inogona kuderedza zvakanyanya mari yekuchengetedza yemakona yakasimbiswa kongiri yose yebasa hupenyu hwemakumi matatu - makumi mana emakore. Zvimwe zvakakosha zvekureva zvinosanganisira shrinkage-kuderedza admixture uye alkali-silical-silical-silica yekugadzirisa inthabitors. Corrosion-inhibiting admixture haina basa zvishoma pane yakazotevera mazera asi inogona kukurumidza kukura simba. Calcium Nitrite Yakavakirwa Corrosion Inhibitors inowedzera nguva dzekuronga dzevakakomberedza pamusoro pehuremu hwekurapa kunze kwekunge dzakatarwa nekudzoreredzwa kwekudzokorora kugadzirisa.
