Lub zog ntawm pob zeb tuaj yeem nce los ntawm ntau txoj hauv kev:
- Siv cov cement ntawm qib siab dua.
- Siv cov ntxhia sib xyaw zoo li GGBS.
- Siv cov dej qis rau cement piv (W / C).
- Kev siv cov angular aggregates zoo.
- Compaction tsim nyog.
Hais txog qhov no, dab tsi cuam tshuam rau pob zeb muaj zog?
Tej yam cuam tshuam rau lub zog ntawm Pob zeb . Pob zeb muaj zog raug cuam tshuam los ntawm ntau yam , xws li zoo ntawm raw khoom, dej / cement ratio, coarse/fineaggregate ratio, hnub nyoog ntawm pob zeb , compaction ntawm pob zeb , kub, txheeb ze humidity thiab curing ntawm pob zeb.
Kuj Paub, nws yuav siv sijhawm ntev npaum li cas rau cov pob zeb ua kom tiav 100% ntawm nws lub zog? Feem ntau pob zeb siv sijhawm 28 hnub kom ncav cuag nws 90% lub zog thiab nws yuav txoj kev xav coj infinite lub sij hawm rau ua kom tiav 100 % lub zog.
Tom qab ntawd, lo lus nug yog, puas ntxiv cov cement ntxiv ua pob zeb muaj zog?
Ib qho sib tov nrog me ntsis dej thiab ntau pob zeb mix yuav dryer thiab tsawg workable tab sis muaj zog dua . Rau ua tus pob zeb muaj zog , ntxiv cov cement los yog tsawg xuab zeb. Qhov ze koj nqa qhov piv rau ib tug txawm ib-rau-ib xuab zeb rau cement , cov muaj zog dua qhov ntsuas tau dhau los.
Dab tsi ua kom pob zeb muaj zog?
Hais lus dav, qhov ntau ntxeem tau pob zeb , qhov weaker nws yuav. Tej zaum qhov tseem ceeb tshaj plaws ntawm porosity hauv pob zeb yog qhov ratio ntawm dej rau cement nyob rau hauv themix, hu ua 'dej rau cement' piv. Raws li qhov porosity nce , cov lub zog khov ntawm pob zeb yuav txo.

Vim li cas Tebchaws Meskas thiaj li ua lub zog muaj zog tshaj plaws nyob rau xyoo pua cuaj?
Vim li cas lub tebchaws United States thiaj li ua lub zog muaj zog nyob rau xyoo 19th? Ntau lab tus neeg Amelikas tau tsiv tawm ntawm cov liaj teb mus rau hauv nroog thiab nroog. Cov neeg ua haujlwm hauv lub Hoobkas tau nce mus txog 20 feem pua ntawm cov neeg ua haujlwm los ntawm xyoo 1860. Kev hloov pauv ntawm lub zog dej mus rau chav ua lub zog txhawb nqa kev tsim khoom
Koj yuav txiav txim siab li cas yog tias cov kua qaub muaj zog lossis tsis muaj zog?
Yog hais tias ib qho acid tsis tau teev tseg ntawm no, nws yog ib qho tsis muaj zog acid. Nws tuaj yeem yog 1% ionized lossis 99% ionized, tab sis nws tseem raug cais raws li cov kua qaub tsis muaj zog. Txhua cov kua qaub uas dissociates 100% rau hauv ions yog hu ua ib tug muaj zog acid. Yog hais tias nws tsis dissociate 100%, nws yog ib tug qaug zog acid
Vim li cas koj thiaj xav kom muaj kev pom zoo ua haujlwm rau koj Scrum ceremonies?
Kev Pom Zoo Ua Haujlwm rau Pab Pawg Scrum. Cov ntawv cog lus ua haujlwm yog cov txheej txheem / kev qhuab qhia / txheej txheem uas pab pawg pom zoo ua raws yam tsis ua tsis tau ua kom lawv tus kheej muaj txiaj ntsig zoo thiab dhau los ua tus tswj hwm tus kheej ntawm scrum. Cov ntawv cog lus no pab pab pawg tsim kom muaj kev nkag siab txog qhov nws txhais tau li cas los ua haujlwm ua pab pawg
Yuav ua li cas tshwm sim thaum koj titrate ib tug muaj zog acid nrog ib tug muaj zog puag?
Lub hom phiaj ntawm lub zog acid-muaj zog hauv paus titration yog los txiav txim siab qhov concentration ntawm acidic tov los ntawm titrating nws nrog ib tug yooj yim tov ntawm paub concentration, los yog vice versa, kom txog thaum neutralization tshwm sim. Yog li ntawd, cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus muaj zog yuav ua rau dej thiab ntsev
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
