Ua ke hauv pob zeb yog tus muab tub lim txheej txheem, tab sis nws lub luag haujlwm tseem ceeb tshaj qhov uas cov nqe lus yooj yim cuam tshuam. Kev sib xyaw, cov duab, thiab qhov loj ntawm sib sau ua ke tag nrho cov muaj feem cuam tshuam rau kev ua haujlwm, durability, lub zog, qhov hnyav, thiab shrinkage ntawm lub pob zeb.
Xav txog qhov no, dab tsi aggregates ua hauv pob zeb?
Aggregates ua li 60-80% ntawm cov pob zeb sib tov. Lawv muab lub zog sib zog thiab ntau rau pob zeb . Aggregates nyob rau hauv tej kev sib tov ntawm pob zeb raug xaiv rau lawv cov kev ua haujlwm ntev, lub zog, kev ua haujlwm tau zoo thiab muaj peev xwm kom tau txais qhov ua tiav.
Kuj Paub, yog vim li cas cov xuab zeb siv hauv kev ua vaj tsev? Txawm tias dej ua rau cement yooj yim rau ncuav thiab pab nws kom tawv, cement thiab dej los ntawm lawv tus kheej tsis tuav ua ke zoo heev. Qhov ntxiv ntawm xuab zeb ua cement kev khi ntau dua. Cement sib tov nrog dej thiab xuab zeb ua mortar, paste siv tuav cib ua ke. Thaum koj ntxiv gravel rau qhov sib tov, nws ua pob zeb.
Tom qab, lo lus nug yog, dab tsi yog lub hom phiaj ntawm aggregate?
Lub Hom Phiaj ntawm Aggregates . Qhov loj, khoom ntxhib sib sau ua ke particles tsim cov txheej txheem yooj yim ntawm cov pob zeb. Cov voids nruab nrab ntawm cov ntxhib loj dua sib sau ua ke cov khoom tau sau los ntawm cov me me. Cov cement thiab dej ua ib qho muab tshuaj txhuam uas khi rau sib sau ua ke cov khoom ua ke ua ke thaum nws tawv.
Dab tsi yog 4 yam tseem ceeb ntawm kev sib sau ua ke?
Cov Hom Sib Txawv Sib Txawv . Pawg ntawm sib sau ua ke muaj xws li gravel, xuab zeb, recycled qhob, slag, topsoil, ballast, Hom 1 MOT, thiab geosynthetic sib sau ua ke (cov khoom siv hluavtaws feem ntau siv hauv kev tsim vaj tsev engineering siv los ua kom thaj chaw ruaj khov).

Lub algorithm twg yog siv los nrhiav kev sib koom ua ke ntawm cov khoom uas tus neeg siv khoom tuaj yeem yuav ntawm lub khw muag khoom?
Association Rule Mining Txoj hauv kev zoo tshaj plaws los nrhiav cov qauv no yog Kev Tshawb Fawb Kev Lag Luam Kev Lag Luam, uas yog cov txheej txheem tseem ceeb siv los ntawm cov khw muag khoom loj xws li Amazon, Flipkart, thiab lwm yam los txheeb xyuas cov neeg yuav khoom los ntawm kev nrhiav kev sib koom ua ke ntawm cov khoom sib txawv uas cov neeg siv khoom tso rau hauv lawv "kev yuav khoom. pob tawb”
Koj puas tuaj yeem muab cov khoom sib xyaw ua ke nrog cov khoom siv tag nrho?
Yog li, yog, koj tuaj yeem sib xyaw cov roj hluavtaws thiab cov pa roj kom zoo. Nyob rau hauv qhov tseeb, hluavtaws-blend lub cev muaj zog roj tsuas yog cov pa thiab hluavtaws roj twb tov rau koj. Tab sis, txwv tsis pub muaj xwm txheej ceev, nws tsis yog lub tswv yim zoo
Dab tsi yog qhov sib txawv ntawm cov paj laum yooj yim thiab cov paj laum sib txuas Vim li cas koj thiaj li xaus nrog cov nyiaj ntau nrog cov paj laum?
Txawm hais tias ob hom kev txaus siab yuav loj hlob koj cov nyiaj hauv lub sijhawm, muaj qhov sib txawv loj ntawm ob. Tshwj xeeb, cov paj laum yooj yim tsuas yog them rau tus thawj tswj hwm, thaum cov paj laum sib txuas tau them rau tus thawj tswj hwm ntxiv rau tag nrho cov paj laum uas tau ua dhau los
