Iimveliso zeConcrete Accelerator

iimveliso ze-accelerator zekhonkrithi liqela lemixube yeekhemikhali ezongezwa kumxube wekhonkrithi ukukhawulezisa inkqubo ye-hydration kunye nokukhuthaza uphuhliso lwamandla.. Zikwasetyenziselwa ukunciphisa ixesha lokumisela kunye nokuphucula ukusebenza kwekhonkrithi, kungakhathaliseki uyilo lomxube.

I-accelerators yenye yezona ntlobo zidumileyo zemixube yeekhemikhali zekhonkrithi, zifana nabanciphisi bamanzi kunye nabacutha amanzi. Ezi ziqhelekileyo zongezwa kumxube wekhonkrithi ngokukhawuleza ngaphambi okanye ngexesha lokuxuba, kunye nokusebenza ngokunyusa izinga lokugalela amanzi kumxube wesamente-amanzi.

I-calcium chloride lolona hlobo luxhaphakileyo lwe-accelerating admixture, kodwa zininzi ezinye iindidi ezikhoyo. Ezi ziquka i-sodium thiocyanate, triethanolamine, kunye nezinye nonchloride isantya admixtures.

Ezinye izixube zekhonkrithi zinokuba nezinye iimpawu ezinokuchaphazela ukusetwa kunye nokuqina kwekhonkrithi, ezifana ne-superplasticizers okanye i-air entraining admixtures. Ezinye zezi zinokufumaneka kumgubo, i-slurry okanye i-liquid form.

Inzuzo ebaluleke kakhulu yokusebenzisa i-accelerators kukuba ikhawuleza ixesha lokumisela. Oku kunokonga ixesha elininzi kunye nemali kwiikontraka ezifuna ukugqiba umsebenzi ngokukhawuleza.

Banokunceda abafana abahombisayo ehlotyeni, xa imozulu ishushu ngokwaneleyo ukubavumela ukuba basuse iifom ngaphambili kwaye bangene kwindawo yekhonkrithi ukuze bagqibezele. Ixesha elimiselweyo elikhawulezayo linokwenza kube lula ukufumana umsebenzi wokulungisa wangaphakathi owenziwe ngosuku, utsho uGabriel Ojeda, umongameli weFritz-Pak Corp.

Eyona nto yaziwa kakhulu ikhonkrithi yokukhawulezisa umxube yicalcium chloride, kodwa ezinye izixhobo zinokusebenza kakuhle. Ezi ziquka iikloridi ezinyibilikayo, carbonates, iisilicates, fluosilicates kunye nezinye iikhompawundi eziphilayo.
