Cov xuab zeb yog cov khoom siv tseem ceeb uas tau siv hauv ntau qhov chaw ntawm tib neeg lub neej. Txawm li cas los xij, tsis yog txhua tus paub tias muaj ntau hom xuab zeb. Ib qho ntawm feem ntau yog hom ntxuav. Hnub no hauv peb kab lus peb yuav tshuaj xyuas kom ntxaws txog nws tus yam ntxwv tshwj xeeb thiab daim ntawv thov.

Nws yog dab tsi?

Ntxuav cov xuab zeb (zoo li lwm hom khoom zoo sib xws) nws muaj nws tus yam ntxwv tshwj xeeb. Yog li, cov cuab yeej tseem ceeb ntawm cov khoom siv no (ua tsaug uas nws tuaj yeem sib txawv los ntawm txhua lwm pawg ntawm cov xuab zeb) yog qhov huv, tsis muaj qhov tsis huv.

Yog tias peb xav txog qhov muaj pes tsawg leeg ntawm cov khoom siv los ntawm cov tshuaj lom neeg pom, tom qab ntawd nws yuav tsum tau hais tias qhov nyiaj ntawm qhov tsis huv yuav tsum tsis pub tshaj 0.3% ntawm tag nrho cov ntim.

Ntxuav cov xuab zeb los ntawm ntau qhov ntau thiab tsawg: zoo thiab ntxhib . Ib qho ntxiv, muaj ntau yam xim sib txawv - hauv qhov xwm txheej, koj tuaj yeem pom cov xim grey thiab daj. Cov khoom siv yog siv ntau qhov chaw: los ntawm kev tsim kho mus rau kev tsim toj roob hauv pes. Tib lub sijhawm, nws tsis xav tau kev saib xyuas tshwj xeeb - tsuas yog qhov uas koj yuav tsum nco ntsoov yog qhov tseeb tias thaum khaws cia koj yuav tsum tiv thaiv cov khoom los ntawm ya raws nkag mus. Tus qauv ntawm cov khoom siv ntxuav yog tus yam ntxwv ntawm qib siab ntawm homogeneity.

Ntxuav cov xuab zeb yog hu ua qhov no vim tias nws tau ua cov txheej txheem tshwj xeeb ntxuav . Nws yuav tsum nco ntsoov tias muaj ntau txoj hauv kev los ntxuav cov xuab zeb. Yog li, cov khoom siv hu ua hydromechanical tau nrov. Nyob rau tib lub sijhawm, nws yuav tsum nco ntsoov tias txij li kev tsim cov xuab zeb ntxuav yuav tsum tau them nqi zog, nws tus nqi ntau dua tus nqi ntawm qee yam lwm yam khoom siv ntau.

Yam ntxwv

Tag nrho cov yam ntxwv tsim nyog thiab cov khoom ntawm cov xuab zeb ntxhua, uas yuav tsum tau muaj nyob hauv cov khoom siv no, tau qhia hauv cov ntaub ntawv raug cai raws li GOST. Raws li, thaum yuav txheej txheem kev yuav khoom, koj yuav tsum ua kom ntseeg tau tias cov khoom siv tau raws li txhua qhov yuav tsum tau ua, txwv tsis pub, nws yog qhov zoo dua los tsis kam yuav cov ntxhia (lossis thov txo tus nqi), vim nws yuav tsis tuaj yeem ua tiav nws lub luag haujlwm lub hom phiaj.

Cov yam ntxwv tseem ceeb tshaj plaws ntawm cov khoom suav nrog hauv qab no:

• ceev - tus yam ntxwv no yuav tsum yog qib 1, 60 g / cm³;
• pab pawg - lawv qhov loj tuaj yeem yog 0.15 txog 0.5 cm;
• kev nqus tshwj xeeb 1 m³ - daim duab no yog kwv yees li 1.5 g / cm³.

Tseem ceeb! Yog tias cov khoom ua tau raws li cov yam ntxwv tshaj tawm, nws tuaj yeem txiav txim siab tau zoo thiab muag hauv khw ntawm tus nqi tsim nyog.

Saib

Muaj ob peb hom kev ntxuav cov xuab zeb. Txhua hom tsiaj sib txawv hauv nws cov yam ntxwv tseem ceeb (piv txwv li, muaj pes tsawg leeg, qhov loj me, txoj hauv kev rho tawm, thiab ntxiv rau). Feem ntau, cov hom tseem ceeb suav nrog cov hauv qab no:

• alluvial;
• dej;
• tsev;
• quartz;
• hauj lwm;
• loj;
• ntxhib-grained;
• me me;
• noob thiab lwm yam.

Nws yuav tsum tau nyob hauv siab tias txhua ntawm cov ntau yam no tau siv rau lub hom phiaj sib txawv. Nws yog ib qho tseem ceeb kom paub koj tus kheej nrog cov yam ntxwv tshwj xeeb ntawm ib hom twg txhawm rau nkag siab yog tias cov xuab zeb no haum rau koj cov kev xav tau tshwj xeeb.

Cov txheej txheem ntau lawm

Muaj ntau txoj hauv kev tshem cov xuab zeb los ntxuav. Rau feem ntau, lawv txawv nyob ntawm qhov chaw (piv txwv li, dej los yog chaw txua txiag zeb) . Txawm li cas los xij, txhawm rau kom tau txais cov khoom siv huv, nws yog qhov tsim nyog siv cov khoom siv tshwj xeeb, tsim tshwj xeeb rau ntxuav. Feem ntau, cov xuab zeb ntxuav tau los ntawm chaw txua txiag zeb. Kev faib dav, kev nyiam thiab xav tau rau cov khoom siv ntuj no tau piav qhia los ntawm nws cov yam ntxwv thoob ntiaj teb thiab tshuaj. Tom qab cov xuab zeb yog mined, nws mus dhau ob peb theem ntawm kev tu thiab ntxuav.

Xws li cov txheej txheem nyuaj ua rau qhov tseeb tias tus nqi ntawm ib cubic meter ntawm cov khoom yog kwv yees li 800 rubles.

Nws siv rau dab tsi?

Kev siv cov xuab zeb ntxuav yog qhov sib txawv heev. Cov ntaub ntawv no yog qhov tsis tseem ceeb rau kev ua tiav ntawm ntau yam haujlwm. Yog li, thaj chaw tseem ceeb ntawm kev siv cov khoom suav nrog hauv qab no:

• screed;
• tsim cov khoom sib xyaw ua ke;
• dej ntws;
• tsim toj roob hauv pes;
• tsim cov vuas rau cov neeg taug kev taug kev;
• txoj kev tsim kho;
• plastering ua hauj lwm;
• tsim cov qauv sib txawv (piv txwv li, cov hauv paus) thiab ntau ntxiv.

Cov qauv ntawm kev xaiv

Kev xaiv cov xuab zeb yog qhov tseem ceeb rau qhov kawg ntawm koj txoj haujlwm. Tias yog vim li cas hauv txheej txheem ntawm kev xaiv thiab yuav khoom, koj yuav tsum ceev faj thiab ua lub luag haujlwm kom ntau li ntau tau. Cov kws tshaj lij pom zoo kom tsom mus rau cov ntsuas tseem ceeb hauv qab no:

• ua raws li GOST tus yam ntxwv - rau kev txheeb xyuas, tsis txhob yig nug tus muag khoom rau daim ntawv pov thawj ntawm kev ua tau zoo thiab ua raws, nrog rau lwm yam ntaub ntawv uas nws tuaj yeem muab rau koj;
• purity ntawm cov xuab zeb - raws li tau hais los saum no, cov khoom yuav tsum tsis txhob muaj qhov tsis huv;
• tus nqi - nco ntsoov tias cov xuab zeb ntxuav zoo yog kim;
• tus neeg muag khoom - nws tau pom zoo kom yuav cov khoom tsuas yog los ntawm kev ntseeg siab bona fide muag thiab hauv cov khw tshwj xeeb tsim nyog;
• cov neeg siv khoom tshuaj xyuas - nws raug nquahu kom kawm cov ntaub ntawv no ua ntej yuav khoom ntau.

Yog li, ntxuav cov xuab zeb yog hom khoom tseem ceeb tshaj plaws uas ua lub luag haujlwm tseem ceeb hauv ntau ceg ntawm tib neeg kev ua haujlwm.
