Koj puas paub txog pob zeb accelerator?

Concrete accelerator: additive tov rau hauv pob zeb kom sai pib qhov chaw thiab hardening. Cov hom tseem ceeb muaj xws li inorganic ntsev thiab organic tshuaj. Powdered khoom, thiab nws qhov ntau npaum li cas tsuas yog 2% mus rau 3% ntawm cov cement siv rau hauv pob zeb, tsis tau nws tuaj yeem ua rau pob zeb pib pib hauv 5 feeb, thiab cov txheej txheem nrawm kom teeb tsa hauv 12 feeb. Qhov no ua tiav lub hom phiaj ntawm kev teeb tsa sai hauv pob zeb rau kev kho thaum muaj xwm txheej ceev lossis hauv qhov dej thiab qhov av. Teem accelerator yog ib qho tseem ceeb ntxiv rau hauv txoj kev siv tshuaj tua hluav taws. Nws txoj haujlwm yog txhawm rau txhawm rau txhawm rau hydration thiab hardening ntawm cov cement, ua kom muaj zog txaus hauv lub sijhawm luv luv kom tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem tsim tshwj xeeb.

Teem sij hawm: Pib teeb 1-5 min, zaum kawg teeb 5-12 min, haum npaum li cas yog 3-5% ntawm cov khoom siv binder siv.
Cov ntsiab lus ntawm alkali hlau<1%, non-toxic, odorless, non-irritating.
Fineness: 80μm sieve, sieve residue tsawg dua 10%.
Shotcrete thaum ntxov muaj zog yog siab, nrog rau 28-hnub compressive zog tuav tus nqi nce mus txog 80-100%.
Cov khoom siv tshuaj tsuag muaj kev sib raug zoo, tsis muaj corrosive rau steel reinforcement, txhim kho impermeability qib, teem sai sai, tso cai rau ib tug tuab txheej nyob rau hauv ib tug tshuaj tsuag, nrog arches mus txog 130mm thiab phab ntsa ntau tshaj 200mm.
