Accelerator/Cement Accelerator/Concrete Accelerator
Lub accelerator muab faib ua hmoov los yog kua. Nws yog ib txoj haujlwm tseem ceeb ntawm Ministry of Construction hauv xyoo 1997, thiab nws cov kev ua tau zoo dua li cov khoom zoo sib xws hauv tsev. Lub ntsiab tivthaiv yog meta-aluminate, uas yog ib qho tseem ceeb cov khoom rau pob zeb thiab mortar spraying project. Cov khoom no yog dav siv nyob rau hauv high-altitude los yog nqaim ua hauj lwm nto los ua nyias-walled lug (xws li underground engineering slope reinforcement thiab foundation pit wall tiv thaiv, lub tsev qauv kho engineering thiab tiv thaiv engineering).
2. Khoom nta
1. Tom qab cov pob zeb tau txau lawm, qhov chaw pib yog tsawg dua lossis sib npaug li 2 feeb, thiab qhov chaw zaum kawg yog tsawg dua lossis sib npaug li 10 feeb.
2. Lub zog tau nce los ntawm 40-60 feem pua hauv 1 hnub, thiab lub zog poob los ntawm 10-20 feem pua hauv 28 hnub.
3. Cov pob zeb muaj viscosity siab thiab qis rebound tus nqi.
4. Tsis muaj xeb cuam tshuam rau steel tuav.
3. Kev siv tshuaj thiab kev siv:
1. Qhov ntau npaum li cas ntawm cov khoom no yog 3-5 feem pua (xws li qhov hnyav ntawm cov cement), uas tuaj yeem hloov kho raws li qhov sib txawv ntawm cov cement muaj pes tsawg leeg.
2. Ua ntej kev siv tshuaj tsuag, cov cement, xuab zeb, pob zeb thiab cov neeg sawv cev ceev yuav tsum tau qhuav-sib tov sib npaug raws li qhov kev faib ua feem tau npaj rau hauv qhov kev sim, thiab cov dej-cement ratio tuaj yeem hloov kho ua ntej txau thiab khiav tawm.
3. Cov khoom no muaj txiaj ntsig zoo ntawm Portland cement. Yog tias siv lwm cov cement, yuav tsum tau ua qhov kev ntsuam xyuas kom haum.
4. Cov neeg ua haujlwm yuav tsum tau ua kev tiv thaiv.
6. Ntim thiab cia:
1. Cov khoom no tau ntim rau hauv lub hnab yas woven lined nrog zaj duab xis, thiab qhov hnyav ntawm txhua lub hnab yog 25 ± 0.5 kg.
2. Cov kua 250kg / chim yuav tsum muab cia rau hauv qhov chaw qhuav thiab qhov cua nrog lub sijhawm siv tau ntawm rau lub hlis. Nws yog txwv tsis pub siv nws yog tias nws ntub thiab agglomerated.
