Na ikuri ni simede mamada | Na vakailesilesi ni Foaming cecere ni cakacaka me baleta na simede ni sela
iyaya ni vakatotolotaki ni simede vakatotolotaka na kena vakawaicalataki na simede. E dau vakayagataki ena draki batabata, na veika oqo e vakalailaitaka na curing kei na ituvatuva ni gauna ni simede me vakarautaka e dua na totolo cake ., iwalewale ni tara vale vinaka cake.
HYDRASET® e dua na iyaya rawarawa-me-vakayagataki ., vakarau-me-vakayagataki wai admixture ka vakatotolotaka na gauna ni ituvatuva taumada ni kaukauwa kei na simede e dua ki na tolu na gauna totolo cake mai na kena sega ni vakayagataki e dua na admixture .. E vakavinakataka talega na cakacaka ka vakalevutaka na kaukauwa ..
Na veiwaki totolo e dau dosed me vaka na bibi ni simede ena dua na ilawalawa ., dina ga ni so na vakatotolotaki sega ni kloride e levu cake na kena ivakarau veisau. Na dau buli iyaya era vola e dua na iwiliwili ni dosing e vakatututaki ena nodra pepa ni itukutuku ni ka e buli ..
Na veivakatotolotaki yavutaki ena chloride e cakacaka me vaka e dua na veivakauqeti me baleta na veivakabulabulataki ni wai ena simede. These reactions occur in a temperature and time-dependent manner, which means the reaction is quicker as temperatures increase.
Inorganic salt-based accelerators contain nitrates, nitrites or thiocyanates instead of chlorides. They may be more effective at accelerating the hydration of cement, but they can cause corrosion issues in steel reinforcements.
Soluble organic compounds and quick-setting admixtures also speed the hydration of cement. These accelerators can also cause a loss of plasticity and workability in concrete, so they’re not typically used in precast or ready-mix applications.
Retarders counteract the accelerated hardening of concrete caused by hot weather. They work as water reducing agents and delay the initial setting of concrete.
Most of these admixtures are custom blends, o koya gona era cakava na ka e gadreva na precaster me ra cakava ena simede vakatabakidua .. Eso era sa dua na isoqoni ni vakatotolotaki kei na wai-vakalailaitaka na veiwaki . (ASTM C494 Mataqali E veiwaki ni kemikali). Eso tale e oka kina na veitikina e vukea na kena vakalailaitaki na shrinkage ., o cei e dua na kauwai vei ira na dauvakarautaki.
