Pob zeb yog siv dav, siv tau ntev, ib puag ncig tus phooj ywg, thiab cov khoom siv qis, thiab tseem tau lees paub thoob ntiaj teb tias yog cov khoom siv hauv tsev. Txhawm rau tsim cov pob zeb zoo, cov khoom sib xyaw ntawm cov pob zeb yuav tsum raug xam kom raug thiab zoo kawg nkaus. Thaum ib qho kev tsim hybrid tau teeb tsa, thawj txoj haujlwm yuav tsum yog sib tov cov khoom siv raw.
Concrete batching yog hais txog tus qauv ntawm kev kwv yees thiab sib xyaw cov khoom tsim nyog (qhov hnyav lossis ntim) raws li kev sib xyaw tsim, thiab cog rau hauv qhov sib xyaw kom tsim tau ib qho loj ntawm pob zeb.
Los ntawm kev suav zoo tag nrho cov ntaub ntawv siv hauv cov vaj tse pob zeb, qhov sib xws ntawm cov proportions tuaj yeem khaws cia hauv txhua qhov tom ntej.
Vim li cas pob zeb pob zeb tseem ceeb?
Feem ntau, cov khoom siv pob zeb siv peb hom nram qab no:
01. Random ntim Cheebtsam: Cov khoom uas tsis muaj kev tswj xyuas qhov loj thiab cov duab ntawm cov ntim khoom siv yuav ua rau muaj qhov yuam kev loj thiab sib txawv, xws li siv "ghamellas", uas suav cov ghamellas. Txoj kev no yog unscientific kiag li thiab imprecise, thiab yuav tsum tsis txhob raug pom zoo txawm rau ib tug me me project.
02. Batch batching ntawm pob zeb: Batch batching ntawm pob zeb ua tiav los ntawm kev siv lub thawv ntsuas, hauv zos hu ua "ua liaj ua teb lossis ntsuas lub thawv". Cov khoom sib xyaw ua ke xws li cov khoom sib xyaw (Kapachi + xuab zeb) thiab cov cement yog suav nrog kev ua liaj ua teb lossis ntsuas lub thawv, thiab cov kev tiv thaiv tsim nyog yuav tsum tau coj los xyuas kom meej tias cov liaj teb lossis cov thawv ntsuas tau dhau lawm. Txhawm rau xam cov dej ntim, lub ntsuas dej yuav tsum tau siv thaum batching lossis siv lub tank ntim dej ruaj khov.
03. Concrete weighting and batching: Qhov hnyav thiab batching ntawm pob zeb ua tiav los ntawm kev siv qhov hnyav thiab batching los yog qhov hnyav ntawm lub tshuab batching. Hauv cov phiaj xwm loj, cov nroj tsuag tsis siv neeg batching tau tsim los ua kom zoo dua qub thiab zoo sib xws.
Dej yog ib yam khoom tseem ceeb heev, yog li ntawd, qhov siab tshaj plaws ntawm cov dej yuav tsum tau siv thaum sib tov. Yog tias muaj dej me me, kev ua haujlwm ntawm pob zeb yuav raug cuam tshuam, thiab cov dej ntau dhau yuav txo qis lub zog ntawm pob zeb. Dej yuav tsum suav tag nrho hauv litres.
Kev xaiv cov txheej txheem muaj nyob ntawm qhov ntsuas kev ua haujlwm, kev tsim khoom, thiab cov qauv kev ua tau zoo ntawm cov khoom.
Batch ua feem ntau yog ua los ntawm ntim. Qhov tseeb ntawm cov khoom xyaw tseem ceeb heev. Nws yog qhov zoo tshaj los ntsuas cov khoom xyaw es tsis txhob ntsuas qhov ntim ntawm cov khoom xyaw. Nyob rau hauv cov xwm txheej uas hnyav thiab batching tsis tau, batch batching yog qhov zoo tshaj plaws. Nws yog ib txwm pom zoo kom tau txais cov nqi ntxiv, xws li nyob rau lub sijhawm ntev, qhov no tuaj yeem txuag tau cov nqi tseem ceeb.
Nco tseg: Kev siv cov cement yuav tsum tswj qhov tseeb ntawm ± 2%, thiab qhov ntau npaum ntawm cov khoom sib xyaw, cov khoom sib xyaw, thiab cov dej yuav tsum muaj qhov tseeb ntawm ± 3%.
