Nws yog siv raws li lub pob zeb crushed rau txoj kev hauv paus thiab kev tsheb ciav hlau ballast. Nws yog siv raws li ib tug aggregate nyob rau hauv pob zeb. Nws raug rho tawm haujlwm hauv qhov cub nrog crushed shale los ua cov cement. Qee yam ntawm limestone ua haujlwm zoo hauv cov no siv vim lawv muaj zog, ntom pob zeb nrog ob peb qhov pore.
Ib yam li ntawd, tib neeg nug, limestone siv rau dab tsi?
Nws yog cov khoom siv raw rau kev tsim cov kua qaub (calcium oxide), slaked txiv qaub (calcium hydroxide), cement thiab mortar. Pulverized limestone yog siv li ib qho av txias rau neutralize acidic xau (ua liaj ua teb txiv qaub). Yog crushed rau siv li aggregate - lub hauv paus ruaj khov rau ntau txoj kev thiab hauv asphalt pob zeb.
Ib sab saum toj, dab tsi yog cov khoom ntawm Oolitic limestone? Cov nplej ntawm cov xuab zeb los yog cov seem ntawm seashell yog dov nyob ib ncig ntawm lub hiav txwv pem teb thiab raws li lawv ua, lawv sau calcium carbonate (CaCO3). Cov khaubncaws sab nraud povtseg yog tsim thiab cov no muab lub pob zeb nws tus yam ntxwv "qe pob zeb" zoo li, raws li lub pob zeb saum npoo zoo li ntses roe (ntses qe). Li no lub sij hawm oolitic limestone.
Tib neeg kuj nug, Oolitic limestone tsim li cas?
Oolitic limestone yog tsim los ntawm me me spheres hu ua ooiliths uas tau daig ua ke los ntawm cov av nkos. Lawv tsim thaum calcium carbonate tso rau saum npoo ntawm cov xuab zeb dov (los ntawm nthwv dej) nyob ib puag ncig ntawm ntug hiav txwv ntiav.
Vim li cas limestone siv hauv cement?
Cov limestone ua raws li cov noob siv lead ua rau lub cement , zoo dua faib cov tshuaj tiv thaiv cov khoom thiab ua kom cov reactivity ntawm cov cement . Raws li ib txwm muaj unhydrated cement hauv pob zeb , qhov kev hloov pauv no yuav tsis muaj qhov ntsuas tau tiag tiag ntawm qhov siv ntawm ya tshauv.

Kev siv limestone yog dab tsi?
Limestone muaj ntau yam siv: raws li cov khoom siv hauv tsev, ib qho tseem ceeb ntawm cov pob zeb (Portland cement), raws li kev sib sau ua ke rau lub hauv paus ntawm txoj kev, raws li cov xim dawb los yog muab tso rau hauv cov khoom xws li tshuaj txhuam hniav lossis xim, ua cov khoom siv tshuaj lom neeg rau kev tsim cov txiv qaub. , raws li ib tug av txias, thiab raws li ib tug nrov kho kom zoo nkauj
Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
